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 filmcan be a upgrade where FEP will not service the most demanding design hurdles.
Use:
Agglutinant
F4 wax cloth belt, transmission belt combining adhibiting
F4 copper board inner adhibiting
Welding film
Electroanalysis
High temperature adhesive tape material
Anti-corrosion lining
Surface protecting material
Non-metal compensator in thermo-eletric plant
Flameproof electric machinery
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 ~ 260℃
3.Non-flammable,Not sticky, waterproof, oil proof
Water wrapping angle: θ=115℃
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.
