SPECIAL
PC-FR
A flame-retardant polycarbonate thermoplastic used for strong, tough and heat-resistant FDM components requiring controlled fire behaviour and durable mechanical performance.
Material Overview
PC-FR is a flame-retardant polycarbonate-based engineering thermoplastic developed for FDM components used near electrical systems, heat sources and applications with defined fire-behaviour requirements. The polycarbonate base provides toughness, impact resistance, mechanical strength and useful elevated-temperature performance, while flame-retardant additives reduce flame propagation and can support self-extinguishing behaviour in tested formulations. Final performance depends on the exact material grade, specimen thickness, part geometry, print orientation, processing conditions and applicable fire-test method.
APPLICATION
Typical Part Types
Electrical and electronic equipment housings
Battery-cell holders and protective battery components
Sensor housings and control-system enclosures
Cable-management parts, connectors and terminal covers
Protective covers for components located near heat or electrical systems
Automotive electrical housings and non-safety-critical interior components
Railway and transport interior components following applicable material validation
Machine guards, brackets and structural equipment supports
Material Selection Note
PC-FR is suitable when polycarbonate toughness, mechanical strength and heat resistance must be combined with controlled flame-retardant behaviour. The designation PC-FR alone does not confirm a universal UL rating or certify every printed component. Fire classification depends on the exact material grade, specimen thickness, print orientation, conditioning and test method. Gramm reviews the supplier documentation, required fire classification, wall thickness, mechanical load, operating temperature, electrical environment, geometry and production strategy before manufacturing.
