For pressure fittings classified under ASTM D1784-20 cell class 12454-B, dry blends based on Resyn 5763 at 100 phr are injection moulded because the K value 57 reduces melt viscosity and permits filling of multi-cavity tooling at lower injection pressures than K value 65 general-purpose resins. A typical compound uses 100 phr Resyn 5763, 1.8–2.2 phr methyltin mercaptide stabilizer, 0.4–0.6 phr calcium stearate, 0.8–1.2 phr paraffin wax external lubricant, 1.5–2.5 phr acrylic processing aid, and 3.0–5.0 phr acrylic impact modifier. Dry blending is performed in a hot/cool mixer: hot stage 110–120 °C, cool stage 40 °C, batch time 20–30 min, followed by 24 h ageing at 23 °C. Injection moulding of fittings per ISO 1452-3 is performed on a reciprocating screw machine with L/D 20:1 to 25:1, compression ratio 2.0–2.5:1, and a check ring; melt temperature measured by an immersion probe is 185–195 °C, with a residence time not exceeding 5 min above 200 °C. Mould temperature is held at 20–35 °C, injection pressure 90–140 MPa, holding pressure 60–80 MPa, back pressure 0.5–1.5 MPa, screw speed 80–120 rpm. Gate sizing of 0.5–0.8 mm by 2.0–4.0 mm and land length 0.5–1.0 mm is used for elbows and tees to prevent jetting. Demoulding shrinkage is 0.3–0.6 %; parts are pressure tested after 24 h conditioning at 23 ± 2 °C and 50 ± 5 % RH according to ISO 1452-3. The grade is not recommended for pipe extrusion above 110 mm OD because low melt strength causes sag; published data for this specific configuration is limited.
Migration compliance for potable water contact is established under EN ISO 15493 and local national approvals, with migration limits per EU 10/2011; residual vinyl chloride monomer is controlled below 1 ppm and organotin stabilizer selection must follow EU 10/2011 specific migration limits for tin. Avoid amine-containing lubricants or processing aids in this compound because they accelerate dehydrochlorination and form colored complexes with tin stabilizers; if amine-containing masterbatch is introduced from recycled material, dehydrochlorination tests per ISO 182-2 should be run at 180 °C before production.
Because the K value 57 promotes early gelation in the calender gap, calendered rigid film for pharmaceutical blister packaging uses Resyn 5763 as the base resin, producing high gloss with low fish-eye counts. Formulation for 100 phr resin includes 1.2–1.5 phr methyltin mercaptide stabilizer, 0.4–0.8 phr internal lubricant glycerol monostearate, 0.2–0.5 phr external lubricant high-density polyethylene wax, 0.5–1.5 phr acrylic processing aid, 4.0–6.0 phr MBS impact modifier, and 0.005–0.02 phr optical brightener. The compound is dry blended to 100–110 °C, cooled to 40 °C, then gelled in a planetary extruder at 150–170 °C and calendered on a four-roll L-type line with roll temperatures of 175–190 °C; the visible roll gap is operated at 1.05–1.10 friction ratio to maintain a rolling bank 10–15 mm in diameter. Gauge variation is controlled by cross-axis roll crossing and online beta gauge feedback; typical tolerance is ±5 % at 250 µm, with transverse gauge ripple below 2.0 µm. Thermoforming of blisters is run at sheet surface temperature of 120–140 °C, with plug-assist and cavity vacuum of -0.08 to -0.09 MPa to achieve uniform wall thickness in cavities up to 25 mm depth.
Pharmacopoeial compliance is demonstrated under USP <661> or Ph.Eur. 3.1.11 for plastic containers; water vapour transmission is determined by USP <671> and is a function of film thickness. For uncoated 250 µm film, plant specifications are set at 4.0–5.5 g/m²/day at 38 °C/90 % RH; if lower WVTR is required, a PVDC or CTFE coating is added downstream rather than altering the Resyn 5763 calender formulation. Calcium stearate is minimized below 0.5 phr to reduce plate-out on calender rolls during runs longer than 72 h.
On parallel counter-rotating twin-screw extruders with L/D 25:1 to 36:1 and screw diameter 65–93 mm, Resyn 5763-based cellular profiles for decking, window trim, and decorative mouldings are processed. The formulation for a low-density board contains 100 phr Resyn 5763, 6–10 phr acrylic high molecular weight processing aid, 3–8 phr precipitated calcium carbonate with mean particle size 1.0–1.5 µm, 0.5–1.0 phr azodicarbonamide, 0.3–0.6 phr zinc oxide kicker, 1.6–2.4 phr organotin mercaptide stabilizer, 0.8–1.2 phr calcium stearate, 0.4–0.6 phr paraffin wax, and 2–4 phr TiO₂ when exterior weatherability is required. Barrel zone temperatures are set from 140 °C in the feed zone to 168 °C at the screw tip, with die temperature 155–170 °C; stock pressure at the die is maintained at 15–22 MPa, and melt temperature measured before the die is 165–175 °C. The screen pack is 60/80 mesh, and the die gap is set to 0.5–0.8 mm for 8–15 mm thick profiles; drawdown is controlled to 0.85–0.95 to limit cell collapse at the surface. Target density is 0.55–0.70 g/cm³, corresponding to density reduction of 50–70 % from compact PVC-U at 1.40 g/cm³.
Exterior weatherability is evaluated per ASTM D3678-19 for PVC profiles; accelerated weathering uses ISO 4892-2 cycle A. Dark colors require heat buildup testing per ASTM D4803-18 because cellular PVC is more sensitive than compact PVC to surface distortion above 60 °C. Amine blowing agent residues are not present, but residual azodicarbonamide decomposition products are controlled by ventilation and post-extrusion outgassing for 24–48 h before packaging.
If drop impact requirements are low and clarity is prioritized, extrusion blow moulding of rigid PVC bottles from Resyn 5763 can be run without impact modifier. The base formulation is 100 phr resin, 1.5–2.0 phr octyltin mercaptide stabilizer, 0.5–0.8 phr oxidized polyethylene wax external lubricant, 0.6–1.0 phr glyceryl monostearate internal lubricant, and 0.5–1.2 phr acrylic processing aid. Melt temperature is 175–185 °C at the die, with a die gap of 0.8–1.2 mm and die land length 10–15 mm. Blow ratio is kept at 2.0:1 to 2.5:1, mould temperature 15–20 °C, and cycle time 12–18 s for 500 mL bottles. Shot size calculation uses part weight plus 15–20 % flash; extruder screw L/D 24:1 to 30:1 with a barrier screw and shear mixing section is preferred to prevent unmelted PVC granules. Wall thickness distribution is measured with an ultrasonic gauge and maintained at 0.35–0.55 mm; drop impact is evaluated per ASTM D2463-23. Food-contact status requires compliance with FDA 21 CFR 177.1980 and EU 10/2011 with overall migration below <10 mg/dm² and VCM below detection limit. The low K value permits lower melt pressure; however, in tooling with long parison length, melt strength must be supplemented with 5–10 phr acrylic high molecular weight process aid to avoid drawdown thickness deviation.
Rigid PVC bottles extruded without impact modifier should not be filled above 60 °C; hot fill trials are restricted because drop impact at 0 °C may fall below 0.5 J when the wall contains no dispersed rubber phase.
For downstream thermoforming, flat die extrusion of Resyn 5763 compounds is performed on a single-screw extruder with L/D 32:1, grooved feed zone, barrier screw and vacuum vent at -0.08 to -0.09 MPa. Sheet thickness 0.5–1.5 mm is produced from a formulation containing 100 phr resin, 1.2–1.8 phr methyltin mercaptide stabilizer, 0.5–1.0 phr internal lubricant, 0.3–0.6 phr external lubricant, 0.8–1.5 phr acrylic processing aid, and 2.0–4.0 phr MBS impact modifier. Barrel temperatures are 150–190 °C, flat die 180–195 °C, and three-roll stack temperatures 70–90 °C, with roll gap 0.3–0.8 mm below die gap for gloss control. After 24 h conditioning, the sheet is thermoformed at sheet surface 120–150 °C, mold temperature 50–60 °C, plug temperature 90–110 °C, and form air pressure 0.5–0.7 MPa. Wall thickness at tray corners should not fall below 60 % of nominal sheet thickness; this is monitored by sectioning and optical microscopy.
Products include clam shells, food trays, and electronics packaging trays; food-contact compliance follows EU 10/2011 and FDA 21 CFR 177.1980 with overall migration below <10 mg/dm². Static dissipative trays require addition of 2.0–5.0 phr conductive carbon black, which reduces fusion temperature by 3–5 °C and requires lower barrel set points to prevent surface tear. Avoid amine-based antistatic additives because they cause pink discoloration in the presence of tin stabilizers.
In masterbatch practice, Resyn 5763 functions as a low-viscosity carrier resin to dilute high-molecular-weight PVC or to prepare high-flow rigid compounds for thin-wall connectors, wire spools, and cosmetic components. In a dilution route, a concentrate based on 100 phr PVC and 20–30 phr acrylic processing aid or impact modifier is let down with 60–80 % Resyn 5763 dry blend in a twin-screw compounding line with L/D 36:1, barrel temperature 150–180 °C, screw speed 300–500 rpm, and melt temperature 185–195 °C. Torque rheometry at 180 °C and 40 rpm is used to compare fusion times; Resyn 5763-based dry blends typically fuse 30–60 s earlier than K value 65 counterparts at equivalent stabilizer loading. This enables higher line speed in twin-strand pelletizing without exceeding 195 °C melt temperature.
Pelletized compound is tested for MVR at 200 °C/5 kg per ISO 1133-1:2022; typical values fall in the range 2–4 cm³/10 min for unfilled rigid compounds, but published data for this specific configuration is limited and plant trials use torque rheometry and MVR checks rather than relying on published gelation temperatures. REACH registration for the polymer is not required under Article 2(9), but monomer and additive SVHC content must be disclosed; RoHS 2011/65/EU Annex II restricts cadmium, lead, mercury, and hexavalent chromium in electrical/electronic applications.

Resyn 5763 is an aqueous polyvinyl acetate homopolymer dispersion stabilised by polyvinyl alcohol. The product designation 5763 is a grade identifier within the supplier’s vinyl acetate polymer series; it is used as an adhesive base component and binder in paper converting, packaging, and non-structural wood assembly. Published grade-specific data sheets are not universally available, so release testing should rely on the current certificate of analysis from the current trademark holder. Legacy supplier literature nonetheless places the product in a high-solids, medium-viscosity class. Typical nonvolatile content is reported as 55–57 wt% under ISO 3251, Brookfield viscosity as 3,000–5,000 mPa·s at 25°C, pH as 4.0–5.5 under ISO 976, and minimum film-forming temperature as 18–20°C under ISO 2115. The combination of solids and viscosity gives a workable rheology for direct transfer and for dilution with water or plasticiser.
The dispersion belongs to the thermoplastic polyvinyl acetate class rather than to crosslinked thermoset or structural binder families. The emulsion is not intended for continuous load-bearing assemblies. Its principal function is to form a coherent film by coalescence after water removal; the formed film has high room-temperature stiffness, good adhesion to fibre, and moderate water sensitivity unless chemically modified.
| Property | Test method | Typical range |
|---|---|---|
| Nonvolatile content | ISO 3251 | 55–57 wt% |
| Brookfield viscosity, RVT, 20 rpm, 25°C | ISO 2555 / ASTM D1084 | 3,000–5,000 mPa·s |
| pH | ISO 976 | 4.0–5.5 |
| Density | ISO 2811 | 1.10–1.12 g/cm³ |
| Minimum film-forming temperature | ISO 2115 | 18–20°C |
| Glass transition temperature | ISO 11357-2 | approximately 38°C |
| Coarse particles on 45 µm screen | ISO 4576 | <200 mg/kg |
The described profile is typical rather than normative; pH, viscosity, and solids vary between production lots, and field adjustments are required when the dispersion is blended with borax, starch, or carbon black. The residue on a 45 µm screen is a useful incoming-material check because gel particles can generate streak defects on gravure cylinders and slot nozzles.
Resyn 5763 differs from vinyl acetate-ethylene copolymer dispersions primarily in backbone rigidity and water sensitivity. Ethylene co-monomer units depress the glass transition temperature; commercial vinyl acetate-ethylene grades often exhibit a glass transition below 0°C, whereas a polyvinyl acetate homopolymer of this type has a glass transition near 38°C under ISO 11357-2. The higher glass transition produces a harder dry film and stronger wet tack on kraft board in short-compression packaging lines, but it reduces low-temperature flexibility and elongation without external plasticiser. Compared with solvent-borne polyvinyl acetate, the aqueous product removes solvent-handling constraints and permits application on porous substrates, but open time and initial water resistance depend on drying conditions. Compared with urea-formaldehyde or phenol-resorcinol-formaldehyde resins, the dispersion is a film-forming thermoplastic; it cannot develop the dense three-dimensional network required for structural joints. Any substitution for thermoset resins must be limited to non-structural or intermittently wetted applications unless validated under the relevant product standard.
| Material class | Glass transition behaviour | Minimum film-forming temperature | Wet tack on kraft board | Water resistance without crosslinking |
|---|---|---|---|---|
| Resyn 5763 polyvinyl acetate homopolymer | approximately 38°C | 18–20°C | high | low |
| Vinyl acetate-ethylene copolymer | -15 to +5°C | <0°C | moderate | moderate |
| Surfactant-stabilised polyvinyl acetate homopolymer | approximately 38°C | 18–20°C | low to moderate | low |
| Reactive thermoset binder | >100°C after cure | not applicable | low before cure | high after cure |
Film formation and machine behaviour in Resyn 5763 are controlled by particle coalescence rather than molecular crosslinking. When the dispersion is applied to a fibrous substrate, water is removed by absorption and forced convection. As the solids content rises, polyvinyl acetate particles pack and then coalesce above the minimum film-forming temperature. Below 18°C, the dried film may remain particulate and hazy, causing loss of cohesive strength; therefore, substrate temperature and drying air temperature should be maintained above the minimum film-forming temperature until the film has cleared. On a typical roll-to-roll line using a 600 mm knife-over-roll coater at 40 m/min, a wet deposit of 40–60 µm produces a clear film after a three-zone tunnel at 60°C, 75°C, and 90°C. The reported figures are machine-class values and should be adjusted for line speed, substrate porosity, and humidity.
Because polyvinyl alcohol is the protective colloid, the emulsion exhibits high wet tack and short fibre-tear development time on absorbent board. In packaging side-seam bonding, the dispersion is applied through a 0.4 mm slot nozzle at 25–40 g/m² dry coat weight. The wet adhesive must hold the seam closed within the compression section; on a 300 m/min side-seam line with a folding plough and a 2.0 bar nip, fibre-tear failure is typically observed at the substrate failure plane under TAPPI T 402 after 24 h conditioning. This failure mode confirms that the bond line is not the weak point. However, published machine parameters vary with board porosity, coating weight, and adhesive rheology after dilution.
Resyn 5763 is often compounded with plasticisers, borax, starch, or defoamers before final use. Borax addition at 0.5–2.0 wt% based on wet dispersion raises Brookfield viscosity from 3,000–5,000 mPa·s to 15,000–40,000 mPa·s depending on pH and order of addition. The thickening response is not linear; it passes through a maximum and then falls. The mechanism involves polyvinyl alcohol-borate crosslinks, which increase low-shear viscosity but can produce a stringy flow profile that complicates jet nozzle transfer. A turbine impeller operating at 30–60 rpm is preferred for borax pre-dissolution, and the borax solution should be added slowly to avoid local gelation. pH should be buffered between 4.0 and 6.0; alkaline additions above 8.0 promote saponification of acetate groups and destabilise the dispersion.
For flexible bookbinding or tube winding, external plasticiser is sometimes introduced at 5–15 wt% on dry polymer. Dibutyl phthalate is obsolete in many regions; current practice favours non-phthalate plasticisers or benzoate esters. Plasticiser addition lowers the minimum film-forming temperature and improves cold-flex, but it also reduces high-temperature creep resistance. The formulator must verify that the plasticised blend still meets the blocking resistance requirement under ASTM D4946 if used on coated paper. If the dried film remains tacky at 50°C, the plasticiser dose should be reduced.
In non-structural wood assembly, Resyn 5763 is formulated with 2–5 wt% of an acidic metal salt catalyst on wet adhesive. The catalyst lowers pH at the bond line and improves resistance to intermittent water exposure. Legacy literature cites compliance with DIN EN 204 durability class D2 when applied on ash or beech at 150–200 g/m² and pressed for 30–60 min at 20°C. This classification does not extend to structural load-bearing joints under ISO 20152-1. The catalyst should be added as a diluted aqueous solution with continuous mixing at 30–60 rpm using a turbine impeller. Viscosity increases during acid addition and may peak after 15–30 min; therefore, pot life and machine downtime must be considered.
The critical processing window is narrow. Catalyst addition reduces pH from 4.5 to approximately 2.8–3.2. Below 2.8, the emulsion may coagulate within minutes, producing gel particles visible on the 45 µm screen under ISO 4576. Above 4.0, the catalysed film does not develop the required water resistance. Batch temperature should be held below 35°C because low-pH conditions accelerate hydrolysis of polyvinyl alcohol and reduce the protective colloid layer. Do not formulate with amine-based additives or ammonia-neutralised thickeners; these raise pH above 7.0 and suppress the acid catalytic plateau, causing premature thickening or destabilisation.
Storage should be maintained at 5–35°C in vented tanks or drums. Unlike some vinyl acetate-ethylene dispersions, polyvinyl acetate homopolymer emulsions have poor freeze-thaw recovery. If the material is frozen, irreversible coagulation can occur because ice crystals compress and tear the polyvinyl alcohol protective layer. The product should not be processed through high-shear centrifugal pumps or packed in unplasticised polyvinyl chloride pipe; stainless steel or high-density polyethylene lines are preferred. Do not combine with strongly basic additives, including ammonia, morpholine, or amine-based corrosion inhibitors; these raise pH above 8.0 and promote saponification and destabilisation. When viscosity is adjusted with water, addition rates should be limited to avoid local dilution shock.
In spiral paper-tube winding, the dispersion is applied by a transfer roller to the paper ply edge at 25–35 g/m²; the wet ply is wrapped around a mandrel and cut. The wet tack must resist flagging before the first nip roll; this is controlled by line speed, usually 40–80 m/min, and nip pressure of 1.5–3.0 bar. The dried bond is then tested by tearing the tube body at the spiral seam; accepted production is set at a substrate fibre-tear frequency greater than 90% under TAPPI T 402 after 24 h at 23°C and 50% RH.
