Features & Benefits
Uncompromised Fire Safety
It achieves UL 94V-0 (1.5mm) and 5VA (3.0mm) ratings, meeting strict flammability standards for electrical/transport components without secondary coatings.
Precision Molding Efficiency
Medium viscosity (MVR 9.0 cm³/10 min) enables complex mold filling, while easy-release properties reduce cycle times and tool maintenance costs.
Enhanced Longevity & Stability
UV stabilization combats environmental degradation, ensuring color/mechanical retention in outdoor enclosures or lighting components.
