Kaxite expanded PTFE sheet as similar as GORE, KLINGER, TEADIT,etc. It is a universal sheet gasket material for most services, seals rough and irregular surfaces.
Style KXT B302 Expanded PTFE Sheet
Expanded PTFE sheet is an extremely compressible material manufactured from 100% virgin PTFE. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries
Expanded PTFE sheet is an expanded PTFE gasket material designed for use in process piping and equipment in chemical, pulp and paper, food and beverage, and other general industrial applications where resistance to highly aggressive chemicals is required. Expanded PTFE sheet is suitable for use in steel flanges and flanges with irregular surfaces.
Expanded PTFE sheet is made with only pure PTFE resins. It is suitable for use in steel flanges as well as flanges where a highly compressible gasket is required. Expanded PTFE sheet is also suitable for sealing flanges with irregular surfaces. It will not exhibit the cold flow problems associated with virgin PTFE or the hardness problems of some other filled PTFE products. It has excellent sealability, cuts easily, and separates cleanly from flanges after use
Advantage
• Conforms perfectly to the contours of very uneven sealing faces
• Very high sealability especially at very low stresses
• Excellent resistance to chemical corrosion
• Superior resistance to creep and cold flow
• Very clean and soft sealing material
• Non-aging, unlimited shelf-life
• Conforms to FDA standard
• Easy to cut and install
Application
• Used in petrochemical, food and pharmaceutical industries
• Seal nearly all aggressive chemicals 0-14 PH
• Various kinds of flanges and vessel mouths
• Paper industry and medical equipments
• Pneumatic and water systemss
• Steam
• Pump., etc.
