Product Introduction
HS853-2 expanded PTFE gasket is a unique material that expands PTFE into a strong, porous and highly fibrous material. It fundamentally solves the common problems of other types of PTFE sealing materials-creep and cold flow. Compared with pure PTFE gasket and filled PTFE gasket, its performance is greatly improved, and its temperature resistance and acid and alkali resistance are also significantly improved. Because of its strong corrosion resistance, ultra-low temperature resistance, high temperature resistance, creep resistance, cold flow resistance, no pollution, very low friction coefficient, wide operating temperature, will not age, permanent durability, multi-fiber structure makes it as a sealing product with unimaginable toughness, in addition, easy to cut, easy to install, long service life and other characteristics, therefore, it can be used in almost all sealing situations. This has made an important contribution to the development and application of new materials.
