What are the chemical properties of PTFE gaskets?

Fiberglass filled PTFE gasket (modified PTFE gasket): Fiberglass filled PTFE gasket, also known as fiberglass modified PTFE gasket, is made by adding a certain amount of filling agent, such as glass fiber, bronze powder, molybdenum disulfide, graphite, carbon fiber, etc., to polytetrafluoroethylene resin. After high-speed mixing, it is molded and then sintered at high temperature., It has compressibility, recoverability, and sealing properties. Its properties and characteristics demonstrate sealing and torque retention. In terms of cold flow and material creep characteristics, it overcomes the shortcomings of traditional PTFE, and at the same time, it can better maintain bolt load than traditional PTFE, which not only improves the durability of sealing but also reduces flange maintenance.Advantages of fiberglass filled PTFE gaskets: improved wear resistance and chemical resistance; This greatly exceeds the use of traditional PTFE, which not only improves the environment but also saves costs. Suitable for chemical, petrochemical, hydrocarbon reactions, and power plants. Especially suitable for sealing in environments where pollution is not allowed, such as food, pulp, paper, and pharmaceutical industries.

Expanded PTFE gasket: Expanded PTFE gasket is a special material. It has excellent performance in creep resistance, cold flow resistance, ultra-low temperature resistance, and easy installation and replacement. Under very small preload, it can withstand considerable internal pressure even in pressure changing environments, making it very suitable for sealing situations with rough or uneven wear, fragile glass face flanges, and temperature fluctuations. We can choose Gore Klinger Garlock Sealon and other expanded PTFE plates for customers to produce the required sealing gaskets.
