The results showed that,when the addition level of curing agent DCP increased,the Shore A hardness and tensile strength of FKM/EPDM blend increased,but the elongation at break decreased. When the ratio of FKM/EPDM increased,the tensile strength and elongation at break of FKM/EPDM blend decreased,but the cracking resistance under aging was improved.When the addition level of curing agent DCP was 3 phr,and ratio of FKM/EPDM was 30/70,the FKM/EPDM blend had good properties. There was no effect on the improvement of physical properties of FKM/EPDM when MA-g-EPDM was used %K [氟橡胶 %K 三元乙丙橡胶 %K 并用胶 %K 耐高温性能 %K 耐老化龟裂性能 %K 氟橡胶 %K 三元乙丙橡胶 %K 并用胶 %K 耐高温性能 %K 耐老化龟裂性能 %K FKM %K EPDM %K blend %K high-temperature resistance %K long term cracking resistance] %U http://www.rubbertire.cn/gy/xjgy/ch/reader/view_abstract.aspx?file_no=xj20151102&flag=1
