Product Description
Modified PTFE Sheet – Engineered Filled PTFE for Superior Sealing Performance
Kaxite Sealing is a leading China-based manufacturer and supplier of modified PTFE sheets – advanced gasketing materials that push the limits of conventional PTFE. Through the incorporation of specially selected fillers (glass microspheres, barium sulfate, glass fiber, and others), our modified PTFE sheets offer significantly reduced creep relaxation, superior bolt torque retention, and tighter sealing performance compared to virgin PTFE. Available in a range of grades (Style 500 Blue, KXT533, KXT611 Blue, and more), these sheets are specifically engineered for applications where security and reliability are paramount, such as chemical processing, semiconductor manufacturing, construction, and cryogenic services. They combine the outstanding chemical resistance of PTFE with enhanced mechanical properties, delivering longer service life, reduced maintenance, and significant cost savings.
As a trusted factory direct supplier in China, Kaxite offers custom thicknesses and sheet sizes, a wide range of filler systems, and competitive wholesale pricing. Request your price list and free sample →
