Features & Benefits
Superior Flame Retardancy
It meets UL 94 V-0 (3.0mm) and V-2 (1.5mm) standards, ensuring critical safety in high-risk environments like protective gear. Reduces ignition risks and complies with global fire-safety regulations.
Easy Processing & UV Stability
Low viscosity (18 cm³/10 min) enables smooth injection molding and easy release. UV stabilization (EN 170) prevents yellowing/degration, extending product lifespan in outdoor applications.
High Heat & Impact Resistance
Vicat softening temp: 182°C with excellent puncture impact (54 J at 23°C). Ideal for heat-exposed parts like visors, ensuring durability under extreme conditions.
