Characteristics and Applications of Local Made Polytetrofluorethylene FiberHE Zheng-xing Changzhou Xingeheng Polymer Material Co.Ltd., Changzhou jiangsu 213013Abstract:The chemical and physical characteristics and applications of polytetrafluoroethylene （PTFE） fiber are introduced, PTFE is a high molecular linear structure, the melting point is 327 ℃ and decomposition temperature is above 415 ℃. PTFE fiber has good corrosion resistance, low friction factor, nonflame, strong acid and strong alkali resistance, high temperature and low temperature resistance. PTFE fibers are widely used in the refuse burning and dust removal of high sulphur coal.
