Abstract
Disclosed herein is a curable composition comprising ethylene copolymer elastomer, a relatively small amount of a polyamide, and optionally a compatibilizer wherein curable composition demonstrates improved heat aging properties without the loss of tensile strength. Also disclosed is the process for making such curable ethylene copolymer elastomer.
Claims17
A curable elastomer composition, said composition comprising:
- (a) ethylene copolymer elastomer;
- (b) a polyamide having a melting peak temperature of about or greater than about 160° C. as determined by ASTM D3418-08, wherein said polyamide is present in at least an effective amount to improve hot air aging, but not more than 5 phr;
- (c) a curative;
- and
- (d) optionally, compatibilizer.
