Heating special raw material with

??? Expanded Teflon tape with 100% PTFE raw material, which has a fine mesh expanded structure consisting of long fibers and festival. Expanded Teflon tape and has good toughness, high longitudinal and transverse deformation characteristics. It is a disc more ideal sealing material on the threads. But it can not be used with high concentrations of oxygen or oxygen situation at contact. Purpose: Expanded Teflon tape is mainly used in more and thread sealing plate.
