PTFE
Product Description
Tefon bellowsTefon bellows
PFA-FEP(F46) soluble PTFE flm
Tetrafluorobellows can be used as tubular reactor and
exchanger, and tubes for the tank car, storage tank,
container, and discharge in special occasions; It can
be used to replace graphite, ceramic, glass and other
pipes with lower mechanical strength ; It can be used for
pipe misalignment or to balance pipe displacement, size
change caused by climate or other reasons ,and used to
eliminate high-frequency mechanical vibration.
Common specifcations: DN20-DN300, other
specifcations can be customized.
Features
Workability: fanged
High transparency: the lowest refractive index of all
plastics
Aging resistance: can be exposed to ozone, sunlight
for along time, with non-aging properties.
Corrosion resistance: It can withstand all strong acids,
strong oxidants, strong reducing agents and various
organic solvents except molten alkali metals, fuorinatedmedia and all those organic solvents' work above 300°.
