Product Description

FEP Film & FEP Tubular Film
Product Features & Applications Overview
FEP (Fluorinated Ethylene Propylene) Film is a high-performance fluoropolymer film known for its excellent electrical insulation, chemical resistance, and non-stick properties. As a standard product, FEP Film and FEP Tubular Film (heat shrink tubing) are widely used across industries including motor manufacturing, printing machinery, electrical insulation, and food processing equipment. 

1. FEP Film - Key Features

1. High Temperature Resistance - Stable continuous use up to 200°C, suitable for high-heat industrial environments.
2. Excellent Electrical Insulation - High dielectric strength and low dissipation factor, widely used for motor winding/slot insulation and electrical component lining.
3. Outstanding Chemical & Oil Resistance - Resists acids, alkalis, solvents, and oils; performs reliably in motors, machinery, and chemical processing environments.
4. Low Friction / Non-Stick Surface - Extremely smooth surface, ideal as lining film for printing machine rollers and as a release/anti-stick film in manufacturing.
5. High Mechanical Strength & Tear Resistance - Durable under repeated flexing, bending, and mechanical stress.
6. Excellent Dimensional Stability - Maintains shape and thickness under heat and pressure, ensuring consistent performance.
7. Good Weatherability & Moisture Resistance - Low water absorption and strong UV/weather resistance for long-term outdoor or humid-environment use.
8. High Transparency & Flexibility - Clear, flexible film that is easy to cut, wrap, and laminate to fit various equipment shapes.
9. FDA-Compliant / Food-Grade Options Available - Certain grades meet food contact safety standards for food processing equipment.
10. Excellent Weldability / Heat-Sealing Performance - Lower melting point than PTFE allows easy heat sealing, hot air welding, and ultrasonic welding - ideal for fabricating custom sleeves, liners, and storage bags without adhesives.

2. FEP Film - Typical Applications

1. Electrical insulation for motors, transformers, and capacitors
2. Lining/wrapping film for printing machine rollers and belts
3. Release film for rubber, composite, and PCB manufacturing (mold release, anti-stick layer)
4. Cable and wire wrapping insulation
5. Solar panel backsheet/laminate layer
6. Food processing equipment lining (conveyor belts, rollers - food-grade grades)
7. Laminating film for textiles, packaging, and industrial fabrics
8. Protective film for chemical equipment linings
9. Medical device packaging and lining (medical-grade FEP)
10. Lithium battery insulation film

3. FEP Tubular Film (Heat Shrink Tubing) - Typical Applications

1. Roller covering for printing, paper, and textile machinery (anti-stick, smooth surface for ink/material release)
2. Heat-shrink insulation sleeves for cables, wires, and electrical connectors
3. Anti-corrosion lining for pipes, rollers, and shafts in chemical processing
4. Protective sleeves for medical devices (catheters, tubing)
5. Insulation covering for heating elements and cartridge heaters
6. Lining for rubber/silicone rollers to prevent material adhesion
7. Lab and chemical equipment tubing (resistant to acids/solvents)
8. Mandrel/mold covering in composite and rubber molding processes
9. Wire harness protection in automotive and aerospace
10. Anti-stick covering for hot rollers in food packaging machinery
11. Welded/sealed gas storage bags for temporary storage of ozone and other reactive gases (high chemical resistance and weldability of FEP make it ideal for custom-fabricated bag construction)

 

Weldability: FEP has a lower melting point than PTFE (approx. 260-280°C), making it easy to heat-seal, hot-air weld, or ultrasonically weld. This allows FEP Tubular Film to be fabricated into custom shapes such as sleeves, liners, and storage bags - for example, welded gas bags used for temporary storage of ozone and other reactive gases - without the need for adhesives, preserving chemical resistance and performance at the seams.

 

Note: Flat FEP Film is typically used for flat lining/wrapping applications (e.g., inside motor housings or flat lining on rollers), while FEP Tubular Film is used when the material needs to shrink-fit around a cylindrical roller or shaft - a very common requirement for printing machine rollers.
