FEP Film

FEP Film

With outstanding resistance to chemicals, UV radiation, and weathering, FEP film delivers long service life in harsh environments. Its smooth surface, low friction coefficient, and excellent dielectric performance make it an ideal choice for insulation, protection, and release applications in advanced manufacturing and high-reliability industries.

Features:

Excellent chemical resistance to acids, alkalis, solvents, and oils.
Wide operating temperature range (approximately 180 to 205°C).
High transparency with smooth, non-stick surface.
Low coefficient of friction and excellent release properties.
Outstanding electrical insulation and dielectric strength.
Good UV, weather, and aging resistance for long-term outdoor use.
Heat-sealable and easier to process compared with PTFE.
Low moisture absorption and stable dimensional performance.

Applications:

Electrical insulation for wires, cables, and electronic components, Protective film for semiconductor and electronics manufacturing, Release liner for adhesive, composite, and molding processes, Chemical processing equipment linings and covers, Solar, aerospace, and automotive insulation applications, Medical and laboratory equipment protection, Optical and display-related protective layers, High-performance packaging requiring chemical and heat resistance.
