PC FR

PC – Polycarbonate (optical grade)

PC FR

PC FR is a fire-retardant polycarbonate sheet. It is ideal for applications that require fire-retardant materials. Such applications include public transport (trains and buses) and certain electrical devices. Exolon® FR has the fire classification of UL94-V0 and it complies with the requirements R4, R22, R23 and R24 pursuant to fire safety standard EN 45545-2. Polycarbonate sheet is an amorphous thermoplastic with excellent impact strength, good heat resistance, and excellent mechanical strength within the temperature range of -50 to 120 °C. We deliver PC FR as plastic sheets.
