FEP(Fluorinated Ethylene Propylene) series
Brief Introduction:
Fluorinated Ethylene Propylene(FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene.
It basically retained the properties of PTFE. Such as: outstanding high & low temperature resistance, chemical stability, electrical insulation, excellent non-sticky and high mechnical strength properties. But it's more easily formable, more elastic and transparent, only the high temperature resistant lower than PTFE 50 °C
Key Characteristics:
l Excellent chemical resistance
l High purity
l Easy to weld using thermoplastic welding equipment
l Good UV stabillity
l Flame resistant
l Abrasion resistant
l FDA compliant grades available.
Applications:
l Chemical tank liners
l Pump and valve parts
l Semiconductor equipment components
Size:
thickness:1.5 to 50 MM x L200MM Max size:500x500mm
Characteristic
1. High and low temperature preservation
2. -200~200°C high temperature intensity better than F4
3. No-begriming ,and no-stagnant in tube
4. Security and insulation
5. Under 60HZ—60MHZ high and low temperature , permittivity is 2.1
6. If firing, and will still insulate
7. Voltaic are>165 seconds insulation
8. Erode preservation
9. Under high temperature, fluorin and alkali will reaction with PFA, no reaction with other acid.
10. Low water absorption<0.01%
11. No firing in air( oxygen index>95 vol.%)
