中文摘要:
      分析4种牌号（CG-FLT，VitonTM GLT-600S，Tecnoflon? PL855和Tecnoflon? VPL85540）耐低温氟橡胶（FKM）的微观结构并测试其胶料性能。结果表明：CG-FLT，GLT-600S和PL855均为相似结构组成的偏氟醚类FKM，VPL85540还含有全氟甲氧基亚甲基乙烯基醚结构；4种牌号FKM热稳定性从高到低顺序为：VPL85540，GLT-600S，PL855，CG-FLT；4种牌号FKM的相对分子质量从大到小顺序为：PL855，VPL85540，GLT-600S，CG-FLT；VPL85540及其胶料的耐低温性能最好。
英文摘要:
      The microstructure of 4 brands（CG-FLT，VitonTM GLT-600S，Tecnoflon? PL855 and Tecnoflon? VPL85540） of low temperature resistant fluororubber（FKM）and their compound properties were analyzed.The results showed that CG-FLT，GLT-600S and PL855 were all metafluoroethers FKM with similar structures，and VPL85540 contained perfluoromethoxy methylene vinyl ether besides.The thermal stability of 4 brands of FKM from high to low was VPL85540，GLT-600S，PL855，CG-FLT.The molecular weight of 4 brands of FKM from large to small was PL855，VPL85540，GLT-600S，CG-FLT.VPL85540 and its compound had the best low temperature resistance.
