FEP
FEP, fluorinated ethylene propylene, has all the desirable properties
of TFE (PTFE) but with a lower survive temperature of 200 degrees C (392 degrees
F). Unlike TFE, FEP can be injection molded and extruded by conventional methods
into rods, tubes, and special profiles. This becomes a design
and processing advantage over TFE.
It is like TFE in that it is a soft material with low tensile strength, and
low wear resistance. FEP is chemically inert and insoluble in all but a few exotic solvents.
Like TFE, FEP is manufactured by DuPont and sold under the name of Teflon.
In direct comparison to TFE, FEP has a lower heat resistance (+400 degrees F to +550 degrees F),
a higher coefficient of friction and poorer wear resistance. They
are similar in their electrical properties, chemical inertness,
strength, moisture absorption, and anti-stick characteristics.
Applications include electronic items such as wire covering and
spaghetti tubing linings for pipes in the chemical industry, aircraft
wiring, and glazing for solar energy collectors.
