What is PTFE  and Isostatic Moulding of it

What is PTFE

PTFE is a standard material for gasketing due to its nearly universal chemical compatibility, good performance at temperatures from cryogenic to over 260 °C, and conformability. PTFE is used alone, or with fillers or metal supports, or as a dispersion for impregnating fibers such as aramids for gasketing. In addition to excellent sealing performance, gaskets made with PTFE can be used in a broad range of applications so inventories can be reduced and there is less risk of misapplication.

Isostatic Moulding

The isostatic moulding process makes the PTFE pipe liner very stiff and its surface is not as smooth as paste extruded ones. Due to the manufacturing process, there are bigger spaces between the PTFE particles, increasing the void content of the PTFE pipe liner and making it more permeable.
