Abstract
The present invention is directed to a sulfur vulcanizable rubber formulation comprising 10 phr to 100 phr of at least one partially saturated elastomer comprising repeat units, wherein at most 10% of all repeat units of the elastomer comprise a double bond; 0 phr to 90 phr of at least one diene based elastomer; 40 phr to 200 phr of at least one filler; and 5 phr to 70 phr of at least one hydrogenated plasticizer. This sulfur vulcanizable rubber formulation has been found to be useful in manufacturing tires.
Claims19
A sulfur vulcanizable rubber composition comprising:
- at least one partially saturated elastomer comprising repeat units, wherein at most 15% of all repeat units of the elastomer comprise a double bond, wherein the partially saturated elastomer has a glass transition temperature which is within the range of −52° C. to −60° C.;
- wherein the rubber composition comprises from 80 phr to 95 phr of the partially saturated elastomer and from 2 phr to 8 phr of cis-1,4-polybutadiene rubber having a cis-microstructure content of at least 95%, and wherein the polybutadiene rubber has a glass transition temperature within a range of −90° C. to −115° C.;
- 40 phr to 200 phr of at least one filler;
- 5 phr to 70 phr of at least one hydrogenated plasticizer;
- and 3 phr to 20 phr of a polyoctenamer.
