Four kinds of curing system are used in the test

the influence of the properties of modified ch1orosulfonated polyethylene（MCS） compound with different curing system is studied

and the effect of the amount of crosslinking agent MgO

mechanical properties and heat aging properties are discussed.Research showed that

the comprehensive perforcmance of MCS with the composite curing syetem of metal magnesium oxide and bismaleimide is best.As the adition level of MgO increased

the modulus at 100% elongation

shore A hardness and heat aging properties increased

the elogation at break

tensile strength

and cuing properties changed very little.
