Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. Thermal stability PTFE is one of the most thermally stable plastic materials. There are no appreciable decompositions at 260�°C, so that PTFE, at this temperature, still possesses most of its properties. Appreciable decomposition begins at over 400�°C. Specification: from 200D to 2500D in 2ply,3ply and multiply
