Study of the Properties of Ceramic Particles Filled PTFE Sealing MaterialWANG Ke XIE Su-jiang Institute Research of Pressure Vessel and Process Equipment, East China University of Science and Technology, Shanghai 200237, ChinaAbstract:Ceramic particles filled PTFE sealing material is developed by die pressing and sintering. The tensile strength, compressibility recovery and creep relaxation of this material are studied. The results show that this material has excellent tensile strength, fine compressibility recovery and outstanding resistance to creep relaxation, it can replace imported products used in food, chemical, petrochemical, paper and pharmaceutical industries.[著者文摘]
