Features & Benefits
Superior Flame Safety
It meets stringent UL 94V-2 standards at thin walls (1.5mm/3.0mm) and high oxygen index (ISO 4589-2: 30%). Ideal for electrical components requiring reliable fire resistance.
Effortless High-Speed Molding
Low viscosity (19 cm³/10 min) ensures fast, complete mold filling. Combined with easy-release properties, it reduces cycle times and boosts production efficiency.
Durable Clarity & Weatherability
UV stabilization maintains optical properties (88-89% transmittance at 3mm) and prevents yellowing. Perfect for outdoor or transparent parts needing long-term aesthetics.
