Abstract
A tire having improved tear strength including at least one component comprising a vulcanized elastomer; and up to about 35 parts by weight of polyolefin copolymer per one hundred parts by weight rubber.
Claims20
A tire including at least one tire component comprising:
- a vulcanized rubber;
- and
- up to about 35 parts by weight of polyolefin copolymer per one hundred parts by weight rubber, where said vulcanized rubber forms a three-dimensional thermoset structure and said polyolefin copolymer is dispersed therein.
A tire component prepared by a process comprising the steps of:
- preparing a vulcanizable composition of matter by compounding or blending a rubber, a filler, and a polyolefin copolymer;
- and
- vulcanizing the rubber with at least one vulcanizing agent to form a three-dimensional thermoset structure with the polyolefin copolymer filler dispersed therein.
A tire component comprising:
- a vulcanized rubber;
- from about 1 to about 100 parts by weight per 100 parts by weight rubber of a filler including carbon black, silica, or a mixture thereof;
- and
- from about 5 to about 30 parts by weight per 100 parts by weight rubber of a polyolefin copolymer, where the vulcanized rubber, the filler, and the polyolefin copolymer are fabricated into a tire component, which is a three-dimensional rhermoset rubber article.
