XIFLON FEP SHEET 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.
Outstanding resistance to harsh chemicals, solvents, and long-term UV exposure
Continuous service temperature: −200 °C to +200 °C with reliable performance
Excellent electrical insulation with high dielectric strength and low dissipation factor
High tensile strength, smooth finish, and easy-release non-stick surface
Our FEP sheets are manufactured using precision extrusion technology. During this process, prime grade FEP resin is melted and formed into sheets under carefully controlled temperature and pressure conditions. This guarantees:
Consistent dimensional stability across all product range
Ultra-smooth, defect-free finish free from inclusions or metal particles
No degradation of polymer structure, preserving chemical and thermal resistance
Each batch is tested to ASTM standards to ensure reproducibility and reliability

Download GuideFEP extruded sheets are semi-finished products made from fluorinated ethylene propylene (FEP), a melt-processable fluoropolymer with properties similar to PTFE but easier to fabricate. Unlike PTFE, which cannot be melt-processed, FEP can be extruded using conventional thermoplastic techniques.
Manufacturing process:
Key differences from PTFE sheets:
Standard properties:
In short: FEP extruded sheets combine fluoropolymer strength with clarity and processability, expanding applications beyond PTFE.
FEP sheets are available in a wide range of thicknesses, widths, and lengths for different industries.
Thickness range:
Widths & lengths:
Surface finishes:
Comparison with PTFE sheets:
Need specific gauges or custom rolls? Both standard and tailored options are available.
FEP extruded sheets are popular across industries for their chemical resistance, optical clarity, and insulation properties.
Key industries & applications:
Why FEP over PTFE or PFA?
Bottom line: For clarity, flexibility, and chemical resistance, FEP sheets outperform many other fluoropolymers.
Yes. Unlike PTFE, which resists bonding and forming, FEP is melt-processable, giving it a fabrication advantage.
Bonding options:
Thermoforming & welding:
If you need a fluoropolymer sheet that bonds, seals, or forms into complex shapes, FEP is the go-to choice.
FEP extruded sheets offer a unique balance of processability, transparency, and resistance that sets them apart.
Compared to PTFE:
Compared to PFA:
Compared to ETFE & PVDF:
Industry-specific benefits:
FEP is often the most practical choice where transparency, purity, and fabrication flexibility are required.
