Transparent teflon FEP film High temperature plastic F46 membrane

F46 membrane,FEP release film is made from fluorinated ethylene propylene (FEP) resin. FEP provides the chemical and thermal resistance to withstand aggressive environments, making it an excellent candidate for diaphragms, gaskets, protective linings, sample bags, and containers. Fabricated shapes and contours can be produced via heat sealing and thermoforming.The outstanding weatherability and optical properties of FEP film provide excellent performance in environmental growth chambers and solar collectors.

1. Extremely good adhesion with F4, good heat sealing
Under melting point, it didn't have chemical reaction with other material.
Beyond melting point, it has good adhesion with F4 and metal
2. High and low temperature resistance -85 ~ 200℃
3. Not sticky, waterproof, oil proof

Water wrapping angle: θ=114℃

4.Non-flammable, Anti-aging

5. Electricity reliability, high insulation

Under 60HZ60MHZ, dielectric constant is 2.1. Even if firing, and it will

still insulate.
Volume resistance > 10^18Ωm
Surface resistance > 2 X 10^13Ω
Voltaic Arc > 165 seconds, insulation
6. High transparency
UV light and visiable light have good penetrating, compared with other
plastic, it has the lowest refraction coefficient.
