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 mixing and molding with molding, and then made by high-temperature sintering. , With excellent compressibility, recovery and sealing. Its unique nature and advanced features exhibit tightness and torque retention. In the cold flow and creep characteristics of the material, it overcomes the shortcomings of the traditional PTFE, and it can maintain the bolt load better than the traditional PTFE, which not only improves the durability of the seal, but also reduces the maintenance of the flange. Graphite-filled filled PTFE gasket Advantages: Low coefficient of friction, good compressive strength, increased wear resistance; making it much more use than traditional PTFE, which improves the environment and saves costs. Suitable for chemical, petrochemical, hydrocarbon reactions and power plants. Dacheng County Yuchen Precision Instrument Accessories Co., Ltd.

Glass fiber filled PTFE gasket is also called glass fiber modified PTFE gasket. It is filled with PTFE resin with a certain amount of fillers, such as glass fiber, bronze powder, molybdenum disulfide, graphite, carbon fiber, etc., and mixed at high speed. After molding with molding, and then made of high-temperature sintering. , With excellent compressibility, recovery and sealing. Its unique nature and advanced features exhibit tightness and torque retention. In the cold flow and creep characteristics of the material, it overcomes the shortcomings of the traditional PTFE, and it can maintain the bolt load better 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 gaskets Advantages: Increased wear and chemical resistance; making its use far exceeds traditional PTFE, which not only improves the environment but also saves costs. Suitable for chemical, petrochemical, hydrocarbon reactions and power plants. It is particularly suitable for sealing occasions where food, pulp, paper, and pharmaceutical industries are not allowed to pollute the environment.
Expanded PTFE gasket:
Expanded PTFE gaskets are truly advanced and unique materials. It has excellent performances such as creep resistance, cold flow resistance, ultra-low temperature resistance, no pollution, easy installation and replacement. Under a small pre-tightening force, even under the pressure fluctuation environment can withstand considerable internal pressure, it is very suitable for rough or uneven wear and easy to break glass surface flange, temperature alternating sealing occasions. We can choose the expansion PTFE board such as Gore, Klinger, Garlock, Sealon to be able to produce the necessary gaskets for the customer.
Pure PTFE gasket:
Full name PTFE gasket abroad also called PTFE gasket or Teflon (Teflon) gasket Flat gasket, V gasket, PTFE rod, tube, plate machined by turning or cutting, Piston rings, ball valve washers, etc., have good properties such as corrosion resistance, anti-aging, and non-conductivity. PTFE pH 0-14 (except molten alkali metal and high temperature, high pressure fluorine). It can have good mechanical strength between -100°C and 100°C. Pressure 10Mpa. Note: At temperatures below -185°C. Teflon gaskets will become brittle. Pure PTFE gasket is a kind of clean sealed product, which will not cause any pollution to any substance it contacts, and can be widely used in food, medicine and other industries.
