Abstract:
A low modulus of elasticity-rubber composition comprising an ethylene-propylene-diene rubber and a softener, wherein(1) the ethylene-propylene-diene rubber has the following properties: (a) a Mooney viscosity at 100Â° C. is from 90 to 130, (b) a diene is ethylidenenorbornene, (c) an iodine value is not more than 20, and (d) the amount of ethylene is not more than 55% based on the total amount of ethylene and propylene; (2) the softener has the following properties: (a) a pour point is not higher than âˆ’40Â° C., and (b) a SP value is from 6 to 8; and the softener is contained in the amount of 300 to 700 parts by weight based on 100 parts by weight of the ethylene-propylene-diene rubber.
