Abstract:
      The relationship between the glass transition temperature（Tg），low temperature retraction temperature（TR10） and brittleness temperature（Tbri） of fluoroelastomer（FKM） was analyzed.The effects of raw rubber，fillers and mixing process on the low temperature brittlement properties of binary and ternary FKM were investigated.The results showed that，Tgof FKM was similar to TR10，which both could reflect the low temperature motion of FKM molecular chain and glass transition temperature.The peroxide-cured FKM with high fluorine content had better low temperature resistance，and the bisphenol-cured binary FKM had worse low temperature resistance.The FKM filled with carbon black N774 had better low temperature resistance.Milling number for plastication had little effect on the low temperature brittleness of FKM.
