Abstract: |
Several high performance specialty elastomers with special properties which can be applied
in the field of non-tire rubber products and used under harsh environments in recent years are reviewed.
Part 4 of this review introduces the developmental history and classification of fluoroelastomers,as well
as describes in detail the composition and features of high performance fluoroelastomers derived from
typical fluoroelastomers (type 1 and type 2 FKM). These high performance fluoroelastomers include
fluoroelastomers with high fluorine content,peroxide curable fluoroelastomers,low temperature resistant
fluoroether elastomers(type 3 FKM)[perfluoromethyl vinyl ether(PMVE)and perfluoromethoxy methyl
vinylether(MOVE) elastomers],perfluoroether elastomers resistant to extreme environments,base-resistant
fluoroelastomers—trifluoroethanol/propylenecopolymer(tetrapropylene fluoroelastomer),trifluoroethanol/
ethylene/PMVE and trifluoroethanol/propylene/vinylidene chloride terpolymers (type 4 FKM),
trifluoroethanol/hexafluoropropylene/vinylidene chloride/ethylene/PMVE pentapolymer(type 5 FKM)
and trifluoroethanol/tetrafluoroethylene copolymer(type 6 FKM). This article reports domestic and foreign
research and development information in the field of high performance fluoroelastomers,focusing on the
recent progress of high performance fluoroelastomers in China. |
