XIFLON PFA FILMS is a semi-finished product manufactured from high-performance perfluoroalkoxy (PFA) resin, sourced from carefully selected and trusted suppliers including XIFLON fluoropolymer resin. Designed for the most demanding industries, our PFA FILMS combine:
Inert to most acids and solvents, ensuring long-term stability.
Performs reliably from −254 °C to +260 °C, with peaks to 310 °C.
Delivers excellent insulation with strength above 6500 V.
High clarity and transparency, free of additives or plasticizers.
Our PFA films are produced by melt-extrusion casting of high-purity resin under strict control. This ensures stable thickness, smooth surfaces, and reliable thermal & electrical performance.
Consistent thickness and width stability across the product range, from 12 µm to 500 µm.
Ultra-smooth, defect-free finish, offering high clarity and excellent light transmission.
No degradation of polymer structure, preserving chemical and thermal resistance
Each batch is tested to ASTM standards to ensure reproducibility and reliability
