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.
Expanded PTFE Sheet
Style KXT B302 Expanded PTFE Sheet
Expanded PTFE gasket sheet is manufactured by expanding 100% virgin PTFE using a proprietary process that
produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting
product exhibits characteristics significantly different than conventional PTFE sheet. This style is much softer and
more flexible than regular PTFE sheet and thus conforms easily to irregular and rough surfaces. In addition, the
material is easier to compress and minimizes creep and cold flow
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.
