When Low-Gloss Automotive Interior Trim Must Pass Humidity Aging Without Paint Adhesion Loss
In automotive interior lower trim, POULOY 7001D is fed through dehumidifying dryers set to a dew point not higher than -40°C and an air temperature of 80°C for 3–4 hours. The target moisture content before plastication is kept below 0.05 wt%; hopper residence above 6 hours is avoided because hydrolysis-induced surface streaking becomes visible in low-gloss mold textures. For this sector, the compound formulation typically uses POULOY 7001D as the continuous matrix at 93–97 wt%, with 2–4 wt% color masterbatch, 0.2–0.5 wt% anti-scratch additive, and 0.1–0.3 wt% primary antioxidant. Low-gloss perception is controlled by mold surface grain depth between 25 µm and 45 µm rather than by additive matting agents alone. Injection molding is carried out on reciprocating screw machines with clamping force from 5,000 kN to 9,000 kN, screw L/D of 20–22, melt temperature profile from 210°C in the rear zone to 240°C at the nozzle, and mold temperature 40–60°C. Melt is held at a back pressure not exceeding 10 bar; back pressure above 15 bar has been associated with pigment dispersion instability and localized yellowing at hot runner drops in production trials. Compliance for interior trims is verified against UN ECE R118 and FMVSS 302 using the horizontal burning test method of ISO 3795. Painted rear surfaces are subjected to 85°C and 85% RH for 168 hours before tape adhesion assessment; mold temperatures below 40°C increase frozen-in orientation near gates and lead to delamination during that test. Finished components include lower A/B/C pillar covers, seat side finishers, glove box outer shells, and center console lower side panels.
Electronic enclosure production operating under IEC 62368-1:2023 must treat thin-walled sections below 1.2 mm as gate freeze-off boundaries rather than cosmetic flow-front concerns. For router housings and network patch panel frames, POULOY 7001D is pre-dried at 80°C for 3–4 hours, and the dried granulate is conveyed with a dry-air loop maintained at or below -50°C dew point. When the target rating is UL 94 HB, the material is processed at 100 wt% without a flame-retardant masterbatch; the melt temperature is then limited to 210–235°C so that gate freeze-off time remains consistent across multi-cavity tools. When a UL 94 V-0 rating is imposed, a brominated flame-retardant masterbatch is added at 18–22 wt%; published data for POULOY 7001D in this specific configuration is limited, and the flow length reduction caused by the masterbatch must be measured on the production mold at the intended wall thickness rather than on a spiral-flow specimen. The process uses sequential valve-gated cold runner molds on clamping units sized 4,000–6,500 kN, with mold temperature 30–50°C, injection velocity 35–80 mm/s, and hold pressure 60–80% of peak cavity pressure. Weld line strength near boss features is evaluated by machining ISO 180 notched Charpy specimens from production parts. Compliance screening covers RoHS Directive 2011/65/EU Annex II substances by IEC 62321-3-1 digestion methods and REACH Regulation (EC) No 1907/2006 candidate list obligations. Terminal parts include smart-home gateway shells, router casings, modular switch frames, wiring duct covers, and server front bezels.
Chill-Roll Sheet Extrusion Lines Producing ABS Sheet for Thermoformed Luggage Shells
Sheet extrusion of POULOY 7001D is conducted on single-screw lines with screw L/D 30–36 and compression ratio 2.5–3.0. The melt temperature at the die entrance is held at 200–220°C, die lips at 220–230°C, and the three-roll stack at 70–90°C. Roll temperatures below 65°C produce visible gloss differential and gauge variance in sheets above 3 mm; measured gauge deviation can exceed ±0.15 mm before downstream thermoforming. For co-extruded sheet, a UV-stabilized cap layer is mixed with 0.3–0.7 wt% hindered amine light stabilizer relative to cap layer weight, while the core layer uses 2–5 wt% color masterbatch and POULOY 7001D as the 94.3–97.7 wt% balance. Incoming lot verification is performed by ISO 1133-1:2022 at 220°C with 10 kg load; a batch-to-batch shift of 0.5–1.0 g/10 min alters sheet sag in plug-assisted thermoforming and must be compensated by line-speed adjustment. Thermoforming is conducted at sheet surface temperatures of 150–180°C; below 140°C, pinhole thinning and plug marks appear in corner draw ratios above 1.5:1. The material specification is controlled under ISO 2580-1, and REACH candidate-list screening is applied to masterbatch components. Terminal products include luggage shells, instrument case blanks, cleanroom door panel blanks, and machinery cover skins.
Moisture uptake above 0.10 wt% at the dryer inlet remains the primary cause of silver streaking in household appliance structural panels produced from POULOY 7001D. In washing machine control panel frames and decorative trim, the compound is typically built from POULOY 7001D at 96–98 wt%, white masterbatch at 2–4 wt%, and a silicone-based processing aid at 0.2–0.5 wt%. Molding uses hot runner manifold temperatures of 220–230°C, mold temperatures 35–55°C, and gate diameters not below 1.0 mm for parts thicker than 2.5 mm; smaller gates in thick boss regions increase jetting and visible flow hesitation lines. The process is controlled against EN 60335-1 for electrical appliance enclosures, with mechanical verification by ISO 178 flexural testing and ISO 180 notched Charpy impact testing on plaques machined from the production tool. Continuous immersion in hot alkaline detergent solutions above 50°C is outside the recommended service envelope; ABS stress cracking is accelerated by sustained exposure to active chlorine compounds and high pH, so the resin is not a substitution for hydrolysis-resistant PP in continuous immersion conditions. Terminal parts include washing machine control panel frames, detergent drawer fronts, appliance end caps, and decorative trim rings for tumble dryers and small domestic appliances.
What Process Boundaries Emerge in Multi-Cavity Office Equipment Housings With Hot Runner Sequential Fill?
In office equipment mold shops, multi-cavity hot runner tools for POULOY 7001D operate with sequential valve gating to control weld line displacement in printer and copier panels. The compound is formulated with POULOY 7001D at 95–99 wt%, carbon black masterbatch at 0.5–1.5 wt%, and an internal lubricant at 0.2–0.4 wt%. Melt temperature is kept at 220–240°C, mold temperature at 45–65°C, fill time at 1.5–3.0 s, and peak cavity pressure at 60–80 MPa. Tools sized for 8–24 cavities require balanced manifold temperature across the hot runner, with maximum zone-to-zone deviation not exceeding 5°C; larger deviation creates non-uniform gate freeze and increases part-to-part mass variance. Material qualification is anchored to UL 746A short-term property requirements and UL 746B long-term heat aging protocols; relative thermal index is not assumed from generic ABS data because POULOY 7001D may not be pre-listed in all OEM RTI databases. Warpage is managed by post-mold fixture cooling at 20°C ambient for 60–120 seconds, followed by dimensional inspection after 24 hours of conditioning at 23°C and 50% RH. Terminal components include printer front covers, copier side panels, scanner frames, and internal paper guide inserts.

Guangdong Polyrocks POULOY 7001D is an acrylonitrile-butadiene-styrene terpolymer specified for sheet extrusion and subsequent thermoforming. Under ISO 2580-2:2019, the material is classed as an ABS moulding and extrusion compound with a high rubber-toughened styrenic matrix. The POULOY family designation identifies the manufacturer’s proprietary ABS range; the 7001D suffix is a formulation code indicating the viscosity, rubber particle size distribution, and additive package intended for sheet products requiring draw depth, surface gloss, and low-temperature crack resistance. The grade is not a general-purpose injection-moulding ABS: its melt rheology, gel content, and thermal stabilisation are adjusted for sheet die flow and thermoforming strain fields.
Property verification before tooling should use the manufacturer’s lot-specific certificate of analysis. The ranges reported herein are indicative of natural-colour extrusion-grade ABS of this class and are not minimum or guaranteed values. Specimen preparation follows ISO 2580-2:2019; conditioning uses ISO 291:2008 at 23 °C and 50 % RH for 24 h. Melt-volume flow rate is measured at 220 °C under 10 kg in accordance with ISO 1133-1:2022 after desiccant drying. Tensile yield stress is obtained on type 1A specimens according to ISO 527-2:2012 at 50 mm/min. Flexural modulus is obtained according to ISO 178:2019. Notched Izod impact strength is measured according to ISO 180:2019 on type 1 specimens. Vicat softening temperature is determined with ISO 306:2022 method B50, using a 50 N load and 50 K/h heating rate. Heat deflection temperature is determined at 1.8 MPa according to ISO 75-2:2013.
How does the 7001D molecular architecture influence sheet extrusion stability?
The molecular design of POULOY 7001D differs from high-flow ABS injection grades in the control of the polybutadiene phase. Production-scale sheet lines processing this grade typically operate at higher melt strength to prevent draw resonance and edge waviness during calender take-off. The styrene-acrylonitrile continuous phase provides stiffness and processability, while the polybutadiene graft phase is retained at a particle size distribution that balances impact resistance and gel formation. In vented single-screw extruders with L/D ratios of 30:1 to 36:1 and barrier screws, the melt temperature is maintained between 210 °C and 230 °C. Below 210 °C, insufficient plasticisation raises motor load and can produce unmolten rubber domains that appear as surface pimples. Above 240 °C, oxidative degradation of the polybutadiene increases carbonyl by-products, causing yellowing and microgel formation in the sheet. The use of a gear pump between the screw tip and the sheet die is recommended to reduce pressure pulsation at die widths above 1.2 m; pressure variation at the pump inlet is typically held within ±0.15 MPa to avoid gauge variation.
Drying before extrusion is mandatory in production environments where relative humidity exceeds 60 %. The resin should be dried in a desiccant-bed dryer at 80 °C for 2 h to 4 h, with a dew point no higher than -30 °C and residual moisture below 0.05 wt%. Moisture in ABS sheet extrusion most often appears as splay, surface micro-voids, and inconsistent thermoforming response. In a production-scale thermoforming cell, sheet surface temperature is usually brought to 150 °C to 180 °C, with core sheet temperatures lower by 10 °C to 20 °C. If the core is too cold, the sheet exhibits elastic recovery and poor mould detail; if the surface is overheated, the sheet may surface-blister from volatile low-molecular-weight styrenic fractions. Regrind addition should be limited to 20 wt% unless the thermoforming scrap is kept free of food-soil contamination and the finished part can tolerate a slight reduction in notched Izod impact.
Comparative Property Envelope versus Injection-Moulding and HIPS Grades
The following table compares the indicative property range for POULOY 7001D with a general-purpose ABS injection-moulding grade and a high-impact polystyrene sheet-extrusion grade. The comparison is intended for material substitution studies only; exact values must be confirmed by lot-specific testing because additive packages and colour masterbatches shift the properties.
| Property | Test standard | POULOY 7001D indicative range | General-purpose ABS injection grade | HIPS sheet-extrusion grade |
|---|---|---|---|---|
| Density | ISO 1183-1:2019 | 1.04–1.06 g/cm³ | 1.04–1.06 g/cm³ | 1.04–1.06 g/cm³ |
| Melt volume-flow rate, 220 °C/10 kg | ISO 1133-1:2022 | 6–8 cm³/10 min | 15–25 cm³/10 min | 5–10 cm³/10 min |
| Tensile yield stress, 50 mm/min | ISO 527-2:2012 | 42–46 MPa | 40–44 MPa | 22–28 MPa |

The lower melt volume-flow rate of POULOY 7001D relative to general-purpose injection ABS is intentional. In sheet extrusion, a higher viscosity at low shear rates supports the web between the die exit and the cooling stack, reducing sag. In injection moulding, the same viscosity would increase filling pressure and may require higher melt temperature; therefore the 7001D formulation is not the direct substitute for thin-wall injection moulding where high flow at high shear rates is the primary requirement.
When deep-draw thermoforming imposes hot-sheet strain gradients exceeding 300 %
In refrigerator liner and door-panel forming, local areal draw ratios can approach 3:1 to 5:1, with corner strain rates that are substantially higher than in flat sheet. The 7001D grade is formulated with an elevated rubber phase and controlled crosslinking of the polybutadiene to resist localised thinning. However, thermoforming grade ABS is not strain-rate independent. At sheet temperatures below 140 °C, the material exhibits a yield-stress increase, and deep-draw corners can develop whitening at thickness reductions beyond 55 %. At sheet temperatures above 185 °C, the sheet may tear under its own weight during prestretch. Heating tunnel settings for a 3.0 mm starting sheet are commonly programmed as a multi-zone profile: 160 °C in the preheat zone, 175 °C in the forming zone, and 150 °C in the clamp-frame edge zone. Tool temperature is maintained at 60 °C to 80 °C to minimise frozen-in stress. Vacuum-assisted forming with 0.6 bar to 0.9 bar cavity vacuum is typical; plug-assist velocity should be reduced when the sheet shows visible necking at the plug contact.
Applications for POULOY 7001D are concentrated in thin-gauge and thick-gauge sheet products that require chemical resistance to detergent solutions and refrigeration foam-blowing agents. The grade is used in refrigerator inner liners where the sheet must survive -30 °C to -40 °C service temperatures after cyclopentane or HFO foaming. In sanitary-ware applications, the material must resist stress cracking from household cleaners; the polybutadiene phase of ABS provides greater cracking resistance than HIPS, but not the solvent resistance of polypropylene. Automotive interior substrates thermoformed from POULOY 7001D are typically grain-embossed and may be back-injected or laminated with soft-touch skins. When the part requires UV stability, a cap layer or paint system is necessary because ABS contains unsaturated polybutadiene that degrades under direct sunlight; unpigmented or natural-colour sheet will yellow over time. Published data for long-term outdoor weathering of this specific grade is limited, and accelerated xenon-arc exposure under ISO 4892-2:2013 should be performed for any exterior-adjacent application.
Sheet Die Flow and Cooling Stack Settings Determine Final Thickness Uniformity
The sheet die gap is normally set 10 % to 20 % greater than the final sheet thickness to account for draw-down and die swell. For a 4.0 mm final sheet, an initial die gap of 4.4 mm to 4.8 mm is used on a coat-hanger die with restrictor-bar adjustment. Chill-roll temperatures between 70 °C and 90 °C are typical for gloss control; lower roll temperatures improve release but may increase residual stress. If the cooling stack is operated at a roll-speed differential above 1 %, the sheet may show curl or edge flutter after slitting. In sheet thicknesses above 8 mm, cooling rate through the thickness creates core residual stresses that lead to post-forming warpage. Therefore, thick-gauge production often requires an annealing stage at 70 °C to 80 °C for 2 h to 4 h before forming.
Compared with polypropylene sheet, POULOY 7001D retains higher modulus, lower shrinkage, and better gloss retention after thermoforming. Compared with HIPS, the nitrile-containing SAN matrix improves environmental stress crack resistance to oils and detergents. Compared with PC/ABS sheet, this grade is easier to process at lower melt temperatures and can be formed on standard acrylic-modified ABS tooling, but its heat resistance and notched impact strength are lower than those of PC/ABS. These differences make 7001D appropriate where styrenic processability and formability are required without the thermal capability of polycarbonate-modified systems.
Standardisation and compliance documentation required for part qualification
Qualification for appliance and automotive programmes normally requires a material declaration covering EU 10/2011 food-contact status when used as a refrigerator liner, RoHS 2011/65/EU with amending directives for electrical and electronic equipment, and REACH candidate-list verification. The manufacturer should supply a statement of composition, a lot-specific melt volume-flow rate, and an impact strength value from the actual production compound. Because ABS is not inherently flame-retardant, the product is typically rated HB under UL 94 at 1.5 mm; if a flame-retardant part is required, a flame-retardant ABS or PC/ABS grade should be selected instead. For medical or food-contact uses, specific migration limits must be evaluated with the final sheet and the intended food simulant; no generic ABS grade should be cleared for all food types without testing. The grade should not be combined with amine-based additives, strong oxidising acids, or excessive regrind that has been thermally degraded; those conditions accelerate chain scission of the polybutadiene and reduce notched Izod impact below 25 kJ/m² in lot testing.
In processing trials, batch-to-batch variance in melt viscosity can be controlled by pre-shipment testing according to ISO 1133-1:2022 and by maintaining regrind ratios below 20 wt%. On a production twin-screw compounding line with 75 mm screw diameter and 36:1 L/D, the product is compounded with antioxidants and processing stabilisers; excessive screw speed beyond 500 rpm can shear-heat the melt above 250 °C and produce gel particles. Extruder purging after processing coloured ABS should use a low-viscosity purge compound, because residual pigment concentrates containing phthalocyanine blue or carbon black can create specks in subsequent natural sheet. The product is not recommended for direct food contact at temperatures above 70 °C unless migration testing under EU 10/2011 demonstrates compliance for the specific simulant and time-temperature condition.
