Features & Benefits
Optimized for Extrusion Efficiency
With a melt flow index of 2.5 ml/10 min, POLYLAC® PA-747R ensures smooth, consistent extrusion for complex profiles. Reduces production downtime and waste, perfect for high-volume manufacturing of automotive trims or appliance components.
Unmatched Impact Resistance
Delivering 37 KJ/m² Izod impact strength (23°C) and 26 KJ/m² at -30°C, this Extrusion ABS withstands drops, impacts, and harsh environments. Ideal for rugged luggage cases or outdoor equipment that demands reliability.
Heat-Resistant Performance
A Vicat softening temperature of 106°C and heat distortion temperature of 83–99°C ensures structural integrity under heat. Critical for refrigerator plating or components exposed to temperature fluctuations.
Use & Applications
- Extrusion Materials: Automotive trims, window seals, and industrial profiles requiring consistent finish.
- Luggage/Suitcases: Lightweight yet impact-resistant shells for travel gear.
- Refrigerator Plating: Glossy, heat-resistant surfaces that maintain aesthetics in appliances.
