DEVELOPMENT AND APPLICATION OF NEW MICROCELLULAR PTFE SEALING GASKET MATERIALXie Sujiang, Wang Ke,Xu LiResearch Institute of Pressure Vessel and Process Equipment, East China University of Science and Technology, Shanghai 200237, China ;Shanghai Junyan New Materials Co. Ltd. , Shanghai 201100, ChinaAbstract:A new polyetrafluorethylene （PTFE） sealing material is developed by using compression sinter technology. The new material has outstanding resistance to creep relaxation and fine recovery, which meets the demand of sealing materials. The main properties of the developed sealing material are tested. The results show that the main properties of the new microcellular PTFE material reach those of the similar products of foreign countries. The sealing material can use in the fild of low load and high distortion compensation.[著者文摘]
