Features & Benefits
Uncompromised Fire Safety
It meets strict UL 94 V-0 (2.2 mm) and 5VA (3.0 mm) flammability standards, ensuring compliance in high-risk electrical applications. No need for secondary flame-retardant treatments.
Effortless High-Temp Processing
Medium flow (MVR 12 cm³/10 min) simplifies injection molding at 280–320°C. UV stabilization and easy mold release reduce rejects. Faster cycles, lower costs.
Design Freedom & Durability
Transparent/translucent color options maintain aesthetics while resisting yellowing. High impact strength (8 kJ/m² at 23°C/-30°C) survives drops and vibrations. Beauty that lasts.
