Modified PTFE Gasket
1.Composite gasket of cladding other non-metal metal with PTFE, which does not only have the chemistry repellence performance of PTFE, but also have good tensile performance due to its core materials. It is indispensable in chemical industry and chemical devices.2.Application: used in the convexity flange and plane pipe flange of high corrosive medium or high cleanness. With very good chemical repellence, it is often used in food processing industry and drinking water projects.3.Temperature: -200---250℃Gasket materialtemperature ℃pressure MPaAsbestos clad plate1501Non-asbestos clad plate2002Copy plate between two layers of asbestosAdd one layer of asbestos plate in the middle2202.5Copy plate between two layers of asbestosAdd one layer of asbestos plate in the middle2202.54. Types A.dissection cut type It has a cladding mouth, so it is an economical gasket used in low pressure, and has very good effects on leveling, compressed metal, porcelain and glass sealing surface. It is also called cladding gasket of Y-type dissection. Cut it into 0.8MM---1MM ring-shaped sheet with cylinder material truck, divide it from the center of outer side thickness, put core materials into the cut mouth, which is about 1.5---2.0MM away from the inner hole.B.folding type It is cladding gasket of left frame-type dissection, with its inner diameter the same with that of flange, so as to prevent the liquid from whirlpooling in the flange, so the inside air has very small expansion amount and good sealing performance. This kind of gasket is often made of reinforcing materials of graphite, open asbestos and rubber. C.mechanical processing type Often used in high-pressure medium, this kind of gasket is cladded with machines. The filling materials are generally constringent materials and rubber. The two ends of 0.4—0.8MM thick strap-shaped PTFE film are heated and covered outside the ring-shaped core materials, to show U shape.
