XIFLON FEP FILMS is a semi-finished product manufactured from high-performance fluorinated ethylene propylene (FEP) resin, sourced from carefully selected and trusted suppliers including XIFLON fluoropolymer resin.
Designed for the most demanding industries, our FEP FILMS combine:
Inert to most chemicals and solvents, stable in harsh conditions.
Service range −240 °C to +205 °C, peaks up to 260 °C.
High insulation strength (>6500 V) across wide frequencies.
Superior release and low surface friction for clean processing.
Our FEP films are produced by melt-extrusion casting of high-purity FEP resin under strict control.
This ensures smooth non-stick surfaces, stable thickness, and reliable chemical, thermal, and 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

While both are forms of Polytetrafluoroethylene, ePTFE (expanded PTFE) is a specialized version with a microporous structure. This gives ePTFE superior conformability, compressibility, and permeability, making it ideal for sealing and filtration applications.
FEP offers excellent chemical resistance, high clarity, and UV stability. It is melt-processable, making it suitable for applications like tubing, wire coatings, and heat shrink films.
