Features & Benefits
Superior Flow for Complex Molds
With a melt flow index of 31 ml/10 min (220°C/10KG), PA-737 fills intricate molds effortlessly, reducing cycle times and minimizing defects in thin-walled designs like automotive dashboards or laptop housings.
Balanced Impact Resistance
Delivering 24 KJ/m² Izod impact strength at 23°C and 10 KJ/m² at -30°C, this material withstands drops, vibrations, and temperature swings—perfect for outdoor equipment housings or rugged industrial components.
Thermal Stability Under Pressure
A Vicat softening temperature of 103°C (1KG load) ensures dimensional stability in high-heat environments, such as under-the-hood automotive parts or heat-resistant appliance panels.
Use & Applications
- Automotive: Trim panels, ventilation ducts, and dashboard components.
- Consumer Electronics: Ultra-thin laptop frames, smartphone casings, and TV bezels.
- Appliances: Vacuum cleaner housings, refrigerator liners, and washing machine panels.
