Product Introduction

PFA film is a novel crystalline perfluorocarbon polymer, a modified product of polytetrafluoroethylene. Its long-term usable temperature range is -80℃ to 260℃. It also possesses excellent chemical stability, outstanding non-stick surface properties, low-temperature mechanical strength, electrical insulation, airtightness, crease resistance, as well as very low water absorption and coefficient of friction. Its atmospheric exposure lifespan can exceed 20 years.

 

Product Properties

Heat Resistance: Can be used for extended periods at -240℃ to 260℃; melting point 305℃
Combustion Performance: Flammability rating UL94-V0, oxygen index 95%
Electrical Properties: Compared to other film materials, PFA film has remarkably reliable performance, high dielectric strength (up to 250KV/mm for 0.025mm film), and extremely low dielectric constant and dielectric loss.
Mechanical Toughness: Excellent anti-stick and low-friction properties; acceptable mechanical performance even at extremely low temperatures.
Long-Term Weather Resistance: Can withstand prolonged outdoor exposure without performance degradation; exhibits good ultraviolet light transmittance
