Notes
Almost totally inert, COILTEF can be used with all industrial
solvents, chemicals, and corrosive materials even at elevated temperatures.
It does, however, react with fluorine, molten sodium hydroxide, and molten
alkali metals.
Teflon's non-stick property allows transport of viscous,
sticky material without line clogging. It also offers outstanding aging
resistance.
COILTEF is manufactured through a fabrication process
which heat sets the coils. The coils should remain stable up to 200°F
for FEP and 300°F for PFA. At higher temperatures the coils will begin
to relax and lose their set. If the application involves elevated temperatures,
in-house testing is recommended.
COILTEF may be steam or chemically sterilized in-line
with any industrial cleaner, solvent, or sterilizing method. Care should
be taken with steam sterilization of COILTEF to prevent coil relaxation.
Testing is recommended.
COILTEF can be manufactured from .085" to 1/2" tubing
ID. The coil diameter can be produced from 3/4" OD to 4" OD.
