PTFE envelope gaskets are composite gaskets consisting of an insert (core) encased in a PTFE envelope,
resulting in a gasket with the chemical resistance of PTFE and the strength and resilience of the core material. The manufacture of PTFE envelopes requires dense PTFE of superior quality to achieve optimum mechanical properties. Applications: GREAT PTFE envelope gaskets are the ideal solution for applications demanding virtually 100% chemical resistance and where the mechanical properties of a compressed gasket material are also needed. They perform whell in the food and process industries where contamination of the medium cannot be permitted.
Description:GREAT 350 PTFE Gasket is molded or skived or cut from virgin PTFE powder or compounds, sheets, rods, tube etc. It has the best chemical corrosion resistance among known plastics. Without being aging, lowest friction coefficient, wear resistance. The unloaded operating temperature range is -180~+260C. CONSTRUCTION: GREAT 350F is PTFE gasket used filler materials such as glass fiber, carbon fiber and graphite etc. The filled PTFE has improved compression strength, better abrasion resistance, high thermal conductivity and lower thermal expansion compared with pure PTFE products. Several types of PTFE gaskets are produced to meet the most demanding application. APPLICATION: GREAT PTFE offers a wide range of compounded products with good mechanical properties, electrical properties, thermal properties, chemical resistance, low friction coefficient and good resistance to wear. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic band for unlubricated compressors. An extended range of improved mechanical and processing properties can be additionally reached by combination of virgin PTFE and different fillers. Different combination offers a variety of different properties described in the following table.
