Claims19
An elastomeric composition comprising a fluorinated additive and a carboxylated rubber selected from the group consisting of XNBR, HXNBR, FKM, ACM, EAM and blends thereof.
A process for improving the physical and low temperature properties of an elastomer composition comprising mixing a carboxylated rubber and a fluorinated additive, wherein the carboxylated rubber is selected from the group consisting of XNBR, HXNBR, FKM, ACM, EAM and blends thereof.
A process for improving the tear strength, abrasion resistance, and compression set of an elastomer composition comprising mixing a carboxylated rubber and a fluorinated additive, wherein the carboxylated rubber is selected from the group consisting of XNBR, HXNBR, FKM, ACM, EAM and blends thereof.
A process for preparing an elastomeric composition comprising admixing a carboxylated rubber and from 0.1 to 1 parts per hundred parts rubber of a fluorinated additive, wherein the carboxylated rubber is selected from the group consisting of XNBR, HXNBR, FKM, ACM, EAM and blends thereof.
