• Customization: Available
• Material: 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°.
