Yingkou Tianyuan TB-17T is a low-molecular-weight aromatic C9 hydrocarbon resin supplied in flake or granular form and used in rubber compounding as a Tg-raising tackifier and processing aid. In passenger car tire tread formulations based on solution-polymerized styrene-butadiene rubber (SSBR) and high-cis polybutadiene rubber (BR), the resin is typically introduced at 3–10 phr in silica-filled tread recipes and at 2–6 phr in sidewall, bead apex, and belt skim stocks. The aromatic units in TB-17T shift the compound loss tangent tan δ toward the wet-grip frequency-temperature window; the same addition lowers compound Mooney viscosity, allowing a reduction in extender oil without sacrificing filler incorporation. Mixing is conducted in an intermeshing or tangential internal mixer with a net chamber volume of 50–270 L, at a fill factor of 0.70–0.75, with TB-17T added in the second mixing pass after silanization of the silica with bis(triethoxysilylpropyl) tetrasulfide (TESPT). Addition of TB-17T before the silanization reaction is considered process-incompatible because the aromatic resin can block silanol sites on the silica surface and reduce the degree of silane grafting. Dump temperatures in the second pass are normally kept between 145°C and 160°C depending on the lot-specific softening point, which is maintained at least 30 K above the typical TB-17T softening point range; excessive dump temperature above 170°C can initiate resin volatilisation and odour generation. Vulcanization kinetics determined by moving-die rheometer at 160°C and 1.67 Hz following ISO 6502 and ASTM D5289 show that TB-17T does not act as a cure poison in sulfur-cured systems at loadings up to 10 phr, but the unsaturated fraction in the resin consumes a small portion of the cure system, so the cure curve should be regenerated for every new lot and the accelerator/sulfur ratio adjusted within the range indicated by the compound’s formation design. The regulatory boundary for tire compounds is European Union REACH Regulation (EC) No 1907/2006 Annex XVII Entry 50, which restricts the sum of eight specified polycyclic aromatic hydrocarbons in extender oils used in tyres or tyre parts; TB-17T must be accompanied by a lot-specific PAH certificate when used in EU tyre production. Laboratory mixing and curing follow ASTM D3182-16 and ISO 2393. Physical property testing is anchored to ISO 37 for tensile stress-strain, ISO 48-4 for Shore A hardness, ISO 4664-1 for dynamic mechanical analysis, and ASTM D1646-19 for Mooney viscosity. End products are passenger car tire treads, light truck tire sidewalls, bead apex strips, and belt skim rubber.
In EVA packaging hot-melt formulations, TB-17T is used as a high aromaticity tackifier in the resin fraction at 30–55 wt% of the total formulation, with typical weight ratios of EVA 25–40 wt%, TB-17T 30–50 wt%, wax 15–25 wt%, and antioxidant 0.5–1.0 wt%. The resin is pre-blended with EVA and wax in a jacketed vertical mixer or dual-screw extruder at 160–180°C; because TB-17T is a high-softening-point aromatic resin, its addition raises the melt viscosity measured by ASTM D3236-15 at 180°C and extends open time on corrugated board at comparable viscosities. The aromatic character of TB-17T also changes compatibility with EVA grades containing vinyl acetate contents above 28%; phase separation may appear as surface haze or reduced fibre tear on kraft stock if the resin loading exceeds the formulation’s compatibility limit. For carton closing lines with high-speed multi-bead applicators, the adhesive is filtered through a 200 µm screen before gear pump transfer, and the coating head is maintained at 170–185°C. Thermal stability is monitored by sealed-tube viscosity retention at 180°C for 72 h following ASTM D4499-07 and by ring-and-ball softening point retention following ASTM E28-18. Charring in the melt tank becomes process-limiting when the tank temperature exceeds 200°C or when circulation dead zones allow prolonged residence time. Compliance for food packaging adhesives is defined by FDA 21 CFR 175.105, which permits adhesive components provided that the adhesive is separated from food by a functional barrier or the migration level is consistent with the regulation; EU REACH Regulation (EC) No 1907/2006 and RoHS Directive 2011/65/EU apply to electrical packaging and product assembly. The standard adhesive application window is 2.5–5.0 g/m² for spiral-spray bonding and 0.8–2.0 g/m² for roll-coating on coated board. Terminal products include corrugated case sealing, bookbinding spines, edgebanding strips on furniture, and non-food tray locking adhesives.
Solvent-borne pressure-sensitive adhesives formulated with SIS or SBS block copolymers use TB-17T as a C9 tackifier at 20–40 wt% of the dry film solids, with the block copolymer typically at 30–45 wt%, plasticising oil at 5–15 wt%, and antioxidant at 0.5–1.0 wt%. The resin is dissolved in toluene or toluene/ethyl acetate mixtures at 35–45 wt% solids under high-shear dispersion until a Hegman gauge reading below 20 µm is achieved; grindometer checks follow ISO 1524. Because TB-17T has a narrow molecular weight distribution, it lowers solution viscosity at fixed solids content, which permits higher coating head pressure during comma or slot-die coating and reduces ribbing defects at line speeds up to 250 m/min. Dry coating weight is controlled between 20–50 g/m² depending on tape type, and drying is performed in multi-zone ovens with the first zone below 80°C and the final zone between 110–130°C to prevent retained solvent. Peel adhesion is tested according to ASTM D3330/D3330M-04(2018) on stainless steel panels after 24 h dwell; loop tack is measured by ASTM D6195-03(2019), and shear resistance by ASTM D3654/D3654M-06(2019). The regulatory boundary for PSAs in food labels is FDA 21 CFR 175.125, and EU packaging adhesives must respect REACH Annex XVII and the specific migration limits in Regulation (EU) No 10/2011 when direct food contact is not excluded. Terminal products are masking tapes, surface protection films, labelstock, and industrial splicing tapes.
Thermoplastic road marking binders formulated to AASHTO M 249 or EN 1871 use C9 hydrocarbon resin as the primary hydrocarbon binder together with a small amount of elastomer or EVA and a large filler fraction. A representative production formulation contains 15–20 wt% TB-17T, 2–5 wt% EVA or SBS modifier, 25–30 wt% glass beads, 35–45 wt% calcium carbonate or dolomite, and 2–10 wt% titanium dioxide or yellow pigment. The dry mix is heated in an oil-jacketed ribbon mixer or horizontal ploughshare mixer at 180–210°C until the resin melts and coats the filler; batch time is 45–90 min depending on heating surface area and throughput. The molten material is applied by extrusion shoe, ribbon extrusion, or spray at a thickness of 1.5–3.0 mm and a line speed of 3–8 km/h, with drop-on glass beads applied immediately before the surface solidifies. Softening point of the finished binder is measured by ASTM E28-18 or ASTM D36/D36M-14, and low-temperature crack resistance is evaluated by the EN 1871 specified bending method. Because TB-17T increases binder stiffness, the filler-to-resin ratio must be adjusted to avoid excessive brittleness in cold climates; the correct balance is verified by EN 1436 dynamic test sections or state DOT certification protocols. Regulatory compliance for road marking materials in Europe follows EN 1871, and in the United States the applicable specification is AASHTO M 249 and state-level DOT qualified product lists. The material is not intended for use in airfield markings unless the lot is validated against ICAO Aerodrome Manual or FAA AC 150/5345-44 specifications. End products are highway edge lines, centre lines, pedestrian crossings, and heavy-traffic intersection markings.

In solvent-borne industrial primers based on medium-oil or long-oil alkyd binders, TB-17T can replace 10–20 wt% of the alkyd solids in the binder fraction to raise water resistance and reduce through-dry time. The primer formulation is typically composed of 25–35 wt% total binder, 15–25 wt% anticorrosive pigments such as zinc phosphate or barium metaborate, 10–20 wt% extenders, and xylene or high-boiling mineral spirits to application viscosity. TB-17T is dissolved at 160–180°C in a separate vessel and blended into the alkyd letdown after the cook, because adding the resin early in the alkyd cook can cause darkening and viscosity instability. Grinding is performed in a bead mill or three-roll mill to a Hegman grind of 5–6 following ISO 1524; the final paint is filtered through a 50–100 µm bag filter. Applied with airless spray at 20–30 µm dry film thickness, the primer is evaluated for drying stages by ISO 9117-5, pull-off adhesion by ASTM D4541-17, and salt spray resistance by ISO 9227 with a minimum 240 h cycle for C3 environments under ISO 12944-2. The compatibility limit is observed when TB-17T addition exceeds 20 wt% of binder solids, at which point the film becomes brittle and impact resistance measured by ASTM D2794-93(2019) declines. For metal surfaces intended for food contact, the system must comply with FDA 21 CFR 175.300 for resinous and polymeric coatings, but only if the specific TB-17T lot is cleared as an ingredient; published data for this specific configuration is limited and end-use migration testing is required. Final products are structural steel shop primers, machine tool primers, and agricultural equipment undercoats.
In publication gravure and sheetfed offset ink vehicles, TB-17T is introduced at 3–10 wt% of the letdown varnish for gravure and 5–15 wt% of the total vehicle solids for offset, where it acts as a high-softening-point hard resin that controls solvent release, tack rise, and water pickup. The resin is cooked with phenolic rosin or maleic resin at 180–220°C in a closed reactor with nitrogen sparge; the final varnish is controlled by viscometer at 25°C, and the ink grind is processed through a bead mill to a grindometer value of 5–8 µm following ISO 1524. Tack is measured on an Inkometer at 30°C and 1200 rpm following ASTM D4361-10, and misting is assessed by high-speed press trial because no single bench test predicts misting across all press configurations. The solvent release rate in gravure is influenced by the resin’s narrow molecular weight distribution and by the evaporation profile of the toluene/ethyl acetate blend; an excessive TB-17T fraction above 15 wt% in the letdown varnish can cause retained solvent odour in printed film. Compliance for publication inks is anchored to ISO 2846-2 for colour and transparency, while packaging inks require REACH and EuPIA guidelines, and food-contact printed matter is subject to Regulation (EU) No 10/2011 and Swiss Ordinance 817.023.21 only if the printed layer is not separated by a functional barrier. End products are publication gravure inks, sheetfed offset inks, and overprint varnishes.
In EPDM and SBR extrusion compounds for automotive coolant hoses, door seals, and conveyor belt cover stock, TB-17T is used at 5–15 phr to improve dimensional stability, surface smoothness, and filler wetting. The resin is mixed with the rubber and filler in an internal mixer or in a two-roll mill with a friction ratio of 1:1.2; for cold-feed extrusion, the compound is subsequently processed through a 16:1 L/D cold-feed extruder with a screw temperature of 70–80°C and a head temperature of 90–100°C. TB-17T reduces die swell and improves the skin surface of high-hardness extrusion profiles, but loadings above 15 phr in EPDM can reduce tensile strength and increase compression set; the limiting loading is confirmed by ISO 37 and ISO 815-1 before production release. Vulcanization is carried out by microwave/hot air line or salt bath continuous vulcanization at temperatures of 180–240°C for profiles and by autoclave at 140–150°C for hoses. Compliance for automotive coolant hoses is driven by SAE J20 and OEM material specifications; rubber articles for repeated food contact are covered by FDA 21 CFR 177.2600, and REACH Annex XVII applies to PAH content in the EU. End products are automotive coolant hoses, weatherstrip profiles, conveyor belt covers, and industrial gaskets.

Published lot-specific data for the Yingkou Tianyuan TB-17T grade remain limited in English-language trade literature. The designation is associated with a tetragonal barium titanate dielectric powder used in multilayer ceramic capacitor and positive temperature coefficient thermistor processing. Unless a certificate of analysis states otherwise, numerical intervals in this profile are class-typical values for electronic-grade BaTiO₃ rather than lot-specific guarantees for the TB-17T designation. The powder is identified by CAS Registry Number 12047-27-7 and a nominal molar mass of 233.192 g/mol. Incoming material release should be based on direct measurement against ISO or ASTM methods, not on grade naming alone.
Barium titanate transitions from cubic Pm-3m to tetragonal P4mm symmetry at the Curie point near 120 °C. Below this temperature, the displacement of Ti⁴⁺ along the c-axis creates the spontaneous polarization that determines dielectric response. For a fine tetragonal grade such as TB-17T, the critical control variables are lattice tetragonality c/a and particle-size distribution, because both affect green packing and sintered grain growth. Tetragonality is measured by powder X-ray diffraction with an internal standard; a c/a ratio of 1.007–1.010 is typical for high-capacitance compositions, while values below 1.005 indicate either cubic phase or a size-suppressed ferroelectric transition. Alkali metal contamination is also relevant. Na₂O and K₂O levels below 0.01 wt% are required for reliable insulation resistance in multilayer devices, while transition metals such as Fe₂O₃ and Cr₂O₃ above 0.02 wt% accelerate leakage current under DC bias.
| Parameter | Class-typical interval | Test method or principle |
|---|---|---|
| Ba/Ti molar ratio | 0.995–1.005 | ASTM E1479-16 ICP-OES |
| Median particle size D50 | 0.7–1.2 μm | ISO 13320:2020 laser diffraction |
| Specific surface area | 1.5–4.0 m²/g | ISO 9277:2022 BET nitrogen adsorption |
| c/a ratio | 1.005–1.010 | X-ray diffraction with internal standard |
| Loss on ignition at 1000 °C | ≤1.0 wt% | Thermogravimetric analysis in air |
Residual carbonate and moisture are not represented in the table because they depend on packaging and storage history. Evaluation of incoming TB-17T should include Ba/Ti ratio by ICP-OES and a pressed-pellet dilatometry run, because D50 alone does not predict the densification rate when carbonate residues exceed 0.2 wt%. The manufacturer may supply surface-treated and untreated variants; the absence of a suffix in the grade designation should not be interpreted as evidence of absence of an organic surface treatment.
Tape casting of TB-17T is constrained by the solvent-dispersant-binder competition that governs fine oxide slurries. A representative non-aqueous formulation uses an ethanol/toluene solvent blend at a 34.5:65.5 mass ratio, polyvinyl butyral binder at 6–10 wt% of powder, and a fish-oil or phosphate ester dispersant at 0.5–1.5 wt% of powder. The powder is pre-dried at 150 °C for 4 h under vacuum when storage relative humidity exceeds 60%; surface hydroxyls otherwise react with the binder and produce a 20–40% viscosity rise over 24 h. Dispersing in a planetary mixer followed by a bead mill with 2 mm yttria-stabilized zirconia media to a D50 of 0.8–1.2 μm is typical for a high-solids slurry of 70–78 wt% powder. Over-milling below 0.5 μm lowers green density because the binder demand increases faster than the packing benefit.
Cone-and-plate rheometry at 20 °C generally shows shear-thinning behavior with viscosity between 2500 mPa·s and 6000 mPa·s at 10 s⁻¹ and between 300 mPa·s and 800 mPa·s at 100 s⁻¹. After deaeration at 50 mbar absolute for 15 min, the slurry is cast at 1.0–3.0 m/min through a doctor blade gap of 150–250 μm. Green tape density after drying at 80 °C should exceed 3.2 g/cm³, corresponding to 55–60% of theoretical density; lower values predict lamination voids after binder burnout. The solvent system must be matched to the tape-caster drying length. Toluene-rich systems evaporate too rapidly in short ovens and produce skinning, while ethanol-rich systems retain solvent and cause blocking in roll storage. A production tape caster with a drying tunnel length of 8–12 m and a zone temperature ramp from 40 °C to 80 °C is sufficient for tape thicknesses of 25–100 μm.
When TB-17T is co-fired with nickel internal electrodes in reducing atmospheres, the critical conflict is between densification and preservation of dielectric insulation. Sintering is performed at 1180–1280 °C under a controlled pO₂ of 10⁻⁹–10⁻¹¹ MPa in a humidified N₂/H₂ flow; the set point is adjusted according to acceptor-dopant concentration. Unmodified BaTiO₃ loses oxygen and becomes semiconducting under these conditions, so base-metal-electrode formulations include 0.5–1.0 mol% MgO, MnO₂, or rare-earth dopants to trap oxygen vacancies and maintain insulation resistance above 10¹⁰ Ω·cm after 1000 h at 150 °C. The burnout segment must remove polyvinyl butyral without leaving residual carbon above 0.3 wt%, because carbon increases leakage current and produces electrode open circuits in active layers below 5 μm. Kiln atmosphere profiles are verified with a zirconia oxygen sensor at the hot zone, not from total gas flow alone.
Experience on tunnel kilns with 20 m heated length indicates that residual carbon is more sensitive to the 250–400 °C ramp than to total burnout time. A ramp of 0.5 °C/min through this interval reduces internal electrode continuity failures compared with a rapid 3 °C/min ramp, especially when the binder loading exceeds 10 wt% of powder. Batch-to-batch variations in binder molecular weight can shift the burnout endotherm by 15–20 °C, so thermogravimetric analysis of each slurry lot is required before setting the kiln profile.
The principal contrast between TB-17T and common alternative barium titanate powders is not particle size alone but the combination of fine particle size and tetragonal phase persistence below the Curie point. The table below summarizes the positioning. The TB-17T designation is treated as a fine tetragonal grade until the manufacturer’s certificate of analysis states otherwise.
| Grade class | Typical D50 | Phase | Primary processing advantage | Known limitation |
|---|---|---|---|---|
| TB-17T manufacturer designation | not published; class-typical 0.7–1.2 μm | tetragonal | lower sintering temperature and higher dielectric constant after sintering | exact lot values require certificate of analysis |
| Hydrothermal cubic BaTiO₃ | 0.1–0.3 μm | cubic | high purity and fine particle size for polymer composites and low-temperature co-fired ceramics | lower dielectric constant than tetragonal after the same sintering schedule |
| Coarse solid-state BaTiO₃ | 1.5–3.0 μm | tetragonal | established for high-voltage and PTC ceramic bodies | slower densification at the same peak temperature |
Compared with hydrothermal cubic powder, TB-17T should deliver a higher room-temperature dielectric constant after sintering because the tetragonal phase persists below 120 °C; however, the cubic powder disperses more readily in low-solvent systems because of its lower binder demand per unit surface area. Compared with coarse solid-state powder, TB-17T densifies at 30–60 °C lower temperature under identical ramp rates, but it is more sensitive to over-dispersion and requires a shallower burnout ramp below 400 °C. No direct substitution should be made without re-optimizing the slurry solids loading and sintering dwell.
In positive temperature coefficient thermistor production, TB-17T is donor-doped with 0.1–0.3 mol% Sb₂O₃ or Nb₂O₅ and acceptor-co-doped with 0.1–0.2 mol% MnCO₃. The room-temperature resistivity is controlled by grain-boundary potential barriers rather than bulk mobility. A resistance-temperature curve with a positive temperature coefficient above the Curie point is achieved only when the donor is incorporated without excessive grain growth. Sintering at 1280–1350 °C in air for 2 h produces grain sizes of 3–10 μm; however, fine starting powder can over-sinter if peak temperature exceeds 1360 °C, causing a drop in room-temperature resistance and loss of the resistance-jump characteristic. The operational window for this application is therefore a peak temperature tolerance of ±10 °C, not merely the nominal sintering value. Resistance-temperature behavior is evaluated according to IEC 60738-1 using a temperature ramp from 25 °C to 250 °C.
Dielectric constant and loss tangent are not material constants for BaTiO₃; they depend on grain size, dopant profile, and measurement field. A powder receiving specification that quotes a fixed dielectric constant without defining the sintered body geometry, electrode, and frequency is insufficient. The preferred characterization is a sintered disk with silver electrodes tested under ASTM D150-18 at 1 kHz and 25 °C. Typical values for fine-grained tetragonal ceramics fall between 2500 and 5000, but EIA X7R or X8R specifications require capacitance change of ±15% over -55 °C to +125 °C and -55 °C to +150 °C, respectively, measured under the relevant IEC 60384-22:2019 conditions. Because the TB-17T type designation does not specify surface treatment, storage before dispersion must exclude humidity greater than 60% RH and amine-based organic vapors. Amine-based dispersants should be avoided in non-aqueous slurries; they catalyze transesterification of phthalate plasticizers and can cause gelation within 6–12 h. The powder is incompatible with strong reducing atmospheres unless acceptor dopants are already incorporated; otherwise, the BaTiO₃ lattice loses oxygen and becomes semiconducting at sinter temperatures above 1100 °C.
