Description

Fluorinated ethylene propylene is colorless and transparent, the copolymerization of tetrafluoroethylene and hexafluoro- propylene, retained full performance of the F4, has excellent chemical stability, excellent non-stick characteristics of temperature permissions below F450 ??C, forming convenient with extrusion, molding, injection molding.

Fluorinated ethylene propylene (FEP or F46) Characteristics:

FEP is milky white, translucent solid with the density of 2.14-2.18g/cm3, smooth surface such as wax, low water absorption, does not exceed 0.01%. Compared with the PTFE, the conventional mechanical properties are similar and toughness at room temperature and creep resistance is better than PTFE. But at elevated temperature is less than PTFE. Its mechanical properties are affected by temperature, but it still has a certain carrying capacity even at 200 ??. The friction factor is only after to PTFE, and decreases with increasing load.
Chemical stability of FEP and PTFE is similar, for all of the dilute or concentrated inorganic acids and alkali it has exceptional stability. It is not affected with alcohols, ketones, hydrocarbons, halogenated hydrocarbons, aromatic hydrocarbons, grease, etc. Only at elevated temperature, it has to ration with fluorine, alkali metals and chlorine fluoridation. Carbon tetrachloride and fluorine-containing compound make FEP swell but can still recover the original shape and performance after the departure of the solvent.
