Flame Retardant PC (FR PC)
UL94 V0 Polycarbonate for Fire-Safe Electrical and Industrial Components

Flame Retardant PC is engineered for applications where fire safety compliance is mandatory. Through advanced flame-retardant formulations, this material achieves reliable self-extinguishing performance while preserving the inherent advantages of polycarbonate—high impact strength, thermal stability, and excellent electrical insulation.
Compared with unfilled PC, FR PC prioritizes safety standards and regulatory compliance, making it a preferred choice for electrical, electronic, and industrial enclosure applications.
