Features & Benefits
High Impact Resistance
POLYLAC PA-747H excels in toughness, with 33 KJ/m² Izod impact strength at 23°C and 22 KJ/m² at -30°C. This ensures parts like refrigerator handles or trim resist cracking in cold environments, reducing breakage during transport or daily use.
Thermal Stability
With a heat distortion temperature of 84°C (1.8 MPa), this ABS resin maintains shape under heat, preventing warping during plating processes. Perfect for oven-finished refrigerator panels that require consistent quality.
Easy Processing
A melt flow index of 3 ml/10 min (220°C) and low mold shrinkage (0.4–0.7%) streamline extrusion and molding. This reduces production downtime and material waste, ideal for high-volume refrigerator plating material manufacturing.
Use & Applications
- Refrigerator Plating Materials: Door panels, interior trim, and decorative components requiring glossy, scratch-resistant finishes.
- Commercial/Industrial Appliances: Vacuum-formed parts like freezer liners or dishwasher panels.
- Extrusion-Based Components: Seals, profiles, and decorative edges with consistent dimensional accuracy.
