PTFE gasket Production

Glass fiber filled PTFE liner (modified PTFE liner):

Glass fiber filled PTFE gasket is also called glass fiber modified PTFE gasket. Filled with PTFE resin such as glass fiber, bronze powder, molybdenum disulfide, graphite, carbon fiber and other fillers, mixed at high speed. After molding, it is formed by compression molding and then sintered at high temperature. , Has excellent compressibility, recycling and sealing. Its unique nature and advanced functions demonstrate compactness and torque retention. In terms of the cold flow and creep characteristics of the material, it overcomes the shortcomings of the traditional PTFE and better maintains the bolt load than the traditional PTFE, which not only improves the durability of the seal, but also reduces the maintenance of the flange. Glass fiber filled PTFE gasket advantages: increase wear resistance and chemical resistance; its dosage far exceeds traditional PTFE, not only improves the environment, but also saves costs. Suitable for chemical industry, petrochemical, hydrocarbon reaction and power plant. It is especially suitable for sealed occasions where food, pulp, paper, medicine and other industries are not allowed to pollute the environment.

Expanded PTFE gasket:

Expanded PTFE gasket is a truly advanced and unique material. It has excellent properties such as creep resistance, cold flow resistance, ultra-low temperature resistance, no pollution, easy installation and replacement. With a small preload, it can withstand considerable internal pressure even under pressure fluctuations. It is very suitable for rough or uneven wear and fragile glass surface flanges, where the temperature is alternately sealed. We can choose Gore, Klinger, Garlock, Sealon and other expanded Teflon plates to produce the gaskets we need.

Pure PTFE gasket:

Teflon gasket foreign full name Teflon gasket or Teflon (Teflon) gasket flat gasket, V gasket, Teflon turning or cutting rod, tube, plate, piston ring, Ball valve gaskets, etc., have good corrosion resistance, anti-aging, non-conductive properties. The pH value of PTFE is 0-14 (except for molten alkali metals and high temperature and high pressure fluorine). It has good mechanical strength between -100℃ and 100℃. 10 MPa pressure. Note: The temperature is below -185℃. The Teflon liner becomes brittle. Pure Teflon gasket is a kind of clean sealing product, it will not cause any pollution to any substance contacted, and can be widely used in food, medicine and other industries.

Graphite filled PTFE liner (modified PTFE liner):

Graphite-filled PTFE gaskets, also known as graphite-modified PTFE gaskets or PTFE gaskets, use PTFE resin to add a certain amount of fillers, such as glass fiber, bronze powder, molybdenum disulfide , Graphite, carbon fiber, etc. After high-speed stirring and molding, it is molded by molding and then sintered at high temperature. , Has excellent compressibility, recycling and sealing. Its unique nature and advanced functions demonstrate compactness and torque retention. In terms of the cold flow and creep characteristics of the material, it overcomes the shortcomings of the traditional PTFE and better maintains the bolt load than the traditional PTFE, which not only improves the durability of the seal, but also reduces the maintenance of the flange. Graphite-filled PTFE gasket advantages: low friction coefficient, good compressive strength, and improved wear resistance; it has a greater use than traditional PTFE, improves the environment, and saves costs. Suitable for chemical industry, petrochemical, hydrocarbon reaction and power plant.
