Flame Retardant PC Applications — UL94 V0 Polycarbonate for Electrical & Industrial Use

Flame Retardant PC (UL94 V0)

Fire-Safe Polycarbonate for Critical Applications

Flame Retardant PC is engineered to combine fire safety compliance with the inherent advantages of polycarbonate: high impact resistance, good heat resistance, and stable dimensional accuracy. By incorporating advanced flame retardant systems into the polymer matrix, this material achieves UL94 V0 performance — making it ideal for applications where fire risk mitigation is essential.

Flame Retardant System & Material Composition

Flame Retardant PC typically uses a halogen-free flame retardant formulation to meet modern safety and environmental standards.
