Product Description
Product Detail
With professional EPTFE Gasket Sheet factory, Ningbo Kaxite Sealing Materials Co.,Ltd is one of the leading China EPTFE Gasket Sheet manufacturers and suppliers.
EPTFE Gasket Sheet
Style KXT B302 EPTFE Gasket Sheet
EPTFE Gasket Sheet is a form of PTFE which is expanded and stretched in many different directions during the manufacturing process. This multi-directional, higher strength material demonstrates a reduced tendency to creep under load at elevated temperatures when ompared with other PTFE gasket materials. EPTFE gasket sheet shows good mechanical recovery over long term compression and temperature fluctuation resulting in very low leakage rates and, due to the very soft texture of the material, conforms perfectly to pitted, uneven flange faces
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.
