transparent PFA FEP F46 membrane for PTFE products welding

PFA fluoropolymer film is made from perfluoroalkoxy (PFA) resin. This film offers the highest continuous use temperature 260°C (500°F) of any melt-processable fluoropolymer film. In addition, PFA provides superior creep resistance at high temperatures, excellent low-temperature toughness, and exceptional flame resistance. With these superior attributes as well as enhanced flex life,PFA film can be a upgrade where FEP will not service the most demanding design hurdles.

Thickness: 0.02~0.3mm
Width: 50~300mm or customized
Length: customized

Main features:

1. Extremely good adhesion with F4, good heatsealing
    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 ~ 260oC

3.Non-flammable, Not sticky, waterproof, oil proof
   Water wrapping angle: θ=115oC

4. 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

5. High transparency
    UV light and visiable light have good penetrating, compared with other
    plastic, it has the lowest refraction coefficient

6. Weather resistance
    Under ozone and sunshine for long time.
