Chang Rubber Polytetrafluoroethylene (PTFE) commonly know by the brand name Teflon, is synthetic
fluoropolymer with exceptional properties. First discovered in 1938, this versatile material possesses unmatched chemical resistance, superior non-stick characteristics and outstanding thermal stability. PTFE has wide range of service temperature, it maintain high strength, toughness and good flexibility -268°C up to 260 °C.

PTFE provides a unique combination of properties such as excellent chemical resistance excellent dielectric properties, hydrophobic, very low coefficient of friction and high heat resistance. PTFE are widely use is various industries like oil & gas, healthcare, food industry, aerospace, medical devices, textiles and pharmaceutical. PTFE is used to deal with extreme application as seals, puddles, scrapers, piston rings, micro machine valve parts, laboratory ware, etc.
