Features & Benefits

Superior Flame Safety

UL 94V-0 certified (1.2 mm) and high oxygen index (37%). Ideal for electronics requiring stringent fire resistance, reducing compliance risks in high-heat environments.

Enhanced Dimensional Stability

10% glass fiber reinforcement minimizes shrinkage (0.45–0.50%) and boosts strength. Ensures precision in complex, thin-wall parts like connectors and housings.

Optimized Processing Efficiency

Low viscosity and easy mold release enable faster cycles. Recommended melt temp: 280–320°C. Lowers production costs while maintaining part consistency.
