IMPROVED WEATHERING PERFORMANCE IN FLAME RESISTANT PC/ABS BLENDS VIA ADDITION OF TAILORED SILICONE COPOLYMERS

摘要

Flame resistant (FR) PC/ABS blends are commonly used as material of choice for portable computer housings and entertainment consoles. Increased demand for aesthetics and design freedom has resulted in need for improved weathering performance on exposure to indirect ultraviolet (UV) radiation. New flame retardant polycarbonate blends using tailored silicone copolymers fill the gap with providing flame resistance at thin gages without compromising on this weathering requirement.
