Features & Benefits
Superior Flame Retardancy
UL 94V-0 certified at 1.5 mm thickness and 36 oxygen index, ensuring critical fire safety in electronics and automotive parts without compromising design flexibility.
Sustainable Performance
Partially bio-circular content (ISCC PLUS mass balance) reduces carbon footprint while maintaining high mechanical strength—perfect for eco-driven industrial procurement.
Easy-Process Efficiency
Low viscosity (19 cm³/10 min MVR) enables smooth injection molding with minimal shrinkage (0.5–0.7%), cutting cycle times and demolding effort in high-volume production.
Use & Applications
- Electrical Enclosures: Flame-retardant housings for switches, connectors, and control units.
- Automotive Components: Dashboard parts, sensor covers, and interior trim requiring impact resistance.
- Industrial Housings: Power tool casings, machinery guards, and safety equipment.
- Consumer Electronics: Charger bodies, smart device frames, and opaque technical parts.
