Features & Benefits
Non-Halogen Flame Retardancy
WONDERLITE® PC-6700 meets strict UL 94 V-0 standards without toxic bromine or chlorine additives. Ideal for eco-conscious manufacturers, it ensures fire safety in high-risk environments like electrical housings and connectors.
Superior Impact Resistance
With 60 KJ/m² Izod impact strength (23°C), this flame retardant PC withstands drops, vibrations, and mechanical stress. Reduces part failure in power tools, automotive components, and industrial equipment.
High Thermal Stability
A heat distortion temperature of 125°C (1.8MPa) ensures performance in heated environments. Use in LED housings or circuit breakers without warping or loss of structural integrity.
Use & Applications
- Circuit breakers & switches
- Transparent covers
- Connectors & relays
- LED lighting housings
- Power tool casings
