Expanded polytetrafluoroethylene gasket is cut or stamped from 100% PTFE expanded polytetrafluoroethylene material. Expanded polytetrafluoroethylene material (ePTFE) is a unique material that expands polytetrafluoroethylene into a strong, strong, and porous material. It is highly fibrotic and not only maintains the unique properties of polytetrafluoroethylene itself - excellent chemical stability (not affected by general chemicals); Extremely low coefficient of friction; Wide operating temperature range; Not aging and permanently durable; Now its multi fiber structure gives it unimaginable toughness as a sealing product, and more importantly, it fundamentally solves the common problems of creep and cold flow in other types of PTFE sealing materials. Compared with pure PTFE gaskets and filled PTFE gaskets, its performance is greatly improved. In addition, its characteristics of easy cutting, easy installation, and long service life make it practically applicable in almost all sealing occasions. This is undoubtedly a remarkable revolution.
Performance characteristics of expanded PTFE gasket:
1. Easy to cut and install
You can make your work easier by mechanically stamping or manually cutting gaskets into any shape.
2. Suitable for sealing rough surfaces
ZD-G1630Expanded polytetrafluoroethylene gaskets have unique compliance molding capabilities, which can produce good sealing effects on rough or damaged flange surfaces without increasing much pressure.
3. Strong resistance to chemical corrosion
Except for a few chemical substances such as molten alkali metals, free fluorine, and tertiary nuclei, it does not react with any other chemical substances and can be used in all sealing occasions within the allowable temperature range (315 ℃), greatly reducing the variety and quantity of sealing components.
4. Good resistance to creep and cold flow
The unique high-density fiber structure gives it strong creep resistance. Due to the absence of any adhesives or additives, its mechanical properties are very stable.
