Advantages of large diameter and PTFE gasket and use

Number of visits: Date:2016-09-19

Pure PTFE gasket PTFE gasket full name abroad also known as Teflon or PTFE gasket (PTFE) gaskets PTFE rods, tubes, plates by mechanical cutting or trimming of flat gaskets, v-shaped gasket, piston rings, washers, ball valve with corrosion-resistant, anti-aging and do not conduct electricity and other good properties.
Large diameter and PTFE pH value 0-14 (molten alkali metals and fluorine under high temperature and high pressure). Teflon at-100 ° c between ~100 has good mechanical strength, pressure 10Mpa.
Large diameter and PTFE gasket Note: at temperatures below-185. PTFE gasket will be brittle. Pure PTFE gasket seal is a clean product, does not come into contact with any material contamination, can be widely used in the food and pharmaceutical industries.
Graphite PTFE gasket (modified PTFE gasket): graphite filled modified PTFE PTFE gasket is also called graphite gaskets or PTFE gaskets are made of shaping polytetrafluoethylene resin added a certain amount of filler, such as fiberglass, bronze powder, molybdenum disulfide, graphite, carbon fiber, high speed after mixing with molded, then through high heat sintering. PTFE gasket with excellent compression, restoration and sealing. PTFE gasket unique properties and advanced features of seal and torque retention. On the creep properties of flow and material, large-diameter overcomes the disadvantages of PTFE PTFE and PTFE gasket can better bolt load than conventional PTFE, which improves the durability of the seal and reducing flange for maintenance.
Graphite filled PTFE gasket advantages: low coefficient of friction, good compressive strength, improve wear resistance; makes the use of large diameter and PTFE greatly exceeds traditional PTFE, which both improve the environment and save the cost. Large diameter and PTFE for chemical and power plants, petrochemicals, hydrocarbons reaction.
Glass fiber filled PTFE gasket (modified PTFE gasket): glass fiber filled PTFE gasket is also called fiberglass modified PTFE gasket is made of shaping polytetrafluoethylene resin added a certain amount of filler, such as fiberglass, bronze powder, molybdenum disulfide, graphite, carbon fiber, high speed after mixing with molded, then through high heat sintering. Glass fiber filled PTFE gasket with excellent compression, restoration and sealing. Glass fiber filled PTFE gasket unique properties and advanced features of seal and torque retention. Glass fiber filled PTFE gasket in flow and material on creep properties, overcomes the disadvantages of PTFE and glass fiber filled PTFE gasket can better bolt load than conventional PTFE, which improves the durability of the seal and reducing flange for maintenance.
Glass fiber filled PTFE gasket advantages: improve abrasion resistance, chemical resistance make use of glass fiber filled PTFE gasket well above conventional PTFE, which both improve the environment and save the cost. Glass fiber filled PTFE gasket for chemical and power plants, petrochemicals, hydrocarbons reaction, glass fiber filled PTFE gasket is suitable for food, pulp and paper, pharmaceutical industry, pollution of the environment are not allowed for seal applications.
