摘要:
The present invention relates to a tire having a rubber tread or rubber layered rubber tread where the rubber tread or rubber tread layers contain a dispersion of polyester phthalate within and on the surface thereof to promote a hydrophilic property for the surface. In one embodiment such promoted hydrophilic property is to promote expelling of water borne mud or snow from within the tread grooves.
摘要:
The invention relates to a tire having a rubber tread comprised of a circumferential outer cap rubber layer which contains a tread running surface and an underlying undertread layer of softer rubber than said outer tread cap rubber layer wherein said undertread layer rubber composition contains short fiber reinforcement.
摘要:
This invention relates to a silica reinforcement-containing rubber composition which contains a functionalized polybutadiene rubber to promote a relatively low hysteretic loss to thereby enhance its desirability for tire sidewall and subtread applications in a sense of advantageously promoting reduced tire rolling resistance without significantly compromising various other desirable tire performance parameters.
摘要:
Pneumatic rubber tire intended for heavy duty service having a cap/base configured tread with a silica-containing specialized cis 1,4-polybutadiene rubber-rich tread cap rubber layer.
摘要:
The present invention relates to a pneumatic rubber tire having an integral innerliner of a sulfur cured rubber composition. The innerliner rubber composition is comprised of at least one elastomer selected from bromobutyl rubber and chlorobutyl rubber which also contains a dispersion therein of ethylene vinyl alcohol polymer.
摘要:
A method of producing a tire including mixing in a non-productive phase at least one elastomer with a polyamide having a melting temperature of less than 180° C. The polyamide is allowed to heat to at least its melting temperature. During the productive phase, at least one curing agent is added to the elastomeric composition. The curing agent may be a sulfur containing curing agent and/or a non-sulfur containing curing agent. The elastomeric composition may optionally include a crystalline EPDM elastomer. The resulting compositions may then be formed into a tire component which may be built into a tire and cured.
摘要:
Pneumatic rubber tire with a component comprised of a silica reinforced rubber composition comprised of specialized polybutadiene rubber, functionalized styrene/butadiene elastomer and cis 1,4-polyisoprene rubber.
摘要:
This invention relates to preparation of precipitated silica-containing EPDM based rubber compositions and their use as components of articles of manufacture such as, for example, tires and industrial products. Such preparation relies upon phase mixing of EPDM based rubber compositions which contain particulate reinforcement, such as for example precipitated silica, which may optionally include exfoliated clay reinforcement, to create an enhanced EPDM rubber composition. In one aspect, the invention relates to a pneumatic rubber tire with a visible outer sidewall rubber layer comprised of such rubber composition.

摘要:
Pneumatic rubber tire with an outer, circumferential tread comprised of a cis 1,4-polybutadiene-rich and silica-rich rubber composition which contains specified elastomers with spatially defined glass transition temperatures, in conjunction with silica and specified carbon black reinforcement.
