The invention relates to a rubber composition prepared with pre-treated precipitated silica and tire with component comprised of such rubber composition. The rubber composition is comprised of at least one diene-based elastomer and said pre-treated precipitated silica together with a sulfur cure package comprised of elemental sulfur together with 1,6-bis (N,N'-dibenzylthiocarbamoyldithio)-hexane crosslinking agent and sulfenamide accelerator.

Rubber prepared with pre-treated precipitated silica and tire with component

The present invention is directed to a method of making a cord-reinforced rubber article, comprising the steps of

Atmospheric plasma treatment of reinforcement cords and use in rubber articles

The invention relates to a rubber composition and tire with tread thereof containing a functionalized elastomer and reinforcement comprised of rubber reinforcing carbon black and a combination of pre-hydrophobated precipitated silica and at least one of hydrophilic precipitated silica together with at least one of short fibers and resin product of methylene acceptor and methylene donor or hydrophilic precipitated silica having been hydrophobated in situ within the rubber composition by a silica coupling agent, optionally together with at least one of reinforcement additive comprised of short fibers and reinforcement additive comprised of resin product of methylene acceptor and methylene donor.

Tire with tread comprised of functionalized elastomer and pre-treated silica

There is disclosed a vulcanizable rubber composition comprising: where R, Rand Rare independently C1 to C8 alkyl or C1 to C8 alkoxy, with the proviso that at least two of R, Rand Rare C1 to C8 alkoxy; Ris C1 to C8 alkyl; Si is silicon; S is sulfur; and Z is Ror of formula II where Ris alkyl, aryl, alkylaryl or arylalkyl;

Rubber composition and pneumatic tire

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.

Tire with rubber component

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.

Rubber composition containing silica reinforcement and functionalized polybutadiene rubber and tires having a component thereof

This invention relates to preparation of nanocomposites comprised of elastomer and a dispersion of an at least partially exfoliated water swellable clay and to rubber compositions containing such nanocomposite and articles of manufacture which contain at least one component thereof. The nanocomposite is prepared by addition of a water suspension of water swellable clay particles to an anionic aqueous emulsion of elastomer particles to form a mixture to which an amine having at least two amine centers is added to intercalate and at least partially exfoliate the water swelled clay particles by an ion exchange within the galleries of the multilayered clay with cation exchangeable ion(s) and to aid in coagulating the elastomer and resultant clay particles to form said nanocomposite.

Preparation of nanocomposite of elastomer and exfoliated clay platelets, rubber compositions comprised of said nanocomposite and articles of manufacture, including tires

The invention relates to a tire with a tread. The tread is composed of at least two defined elastomers having Tg's spaced apart by at least 55&deg; C. to the exclusion of elastomers having Tg's between &minus;30&deg; and &minus;85&deg; C. The tread composition can be reinforced with either carbon black or a combination of carbon black and silica reinforcing fillers.

Tire tread with elastomers of spatially defined Tg's

In a tire having a tread with cap/base construction, a regulated amount of partially crosslinked natural rubber in a tire tread compound increases the uncured ('green') stiffness, tensile strength and tear resistance of a green compound used for the base without adversely affecting physical properties of the tread after it is cured. Such green stiffness is particularly useful in the construction of a tread for a pneumatic tire, which tread is of cap/base construction because stiffness provides requisite dimensional stability of both cap and base (in the tread) during the curing of the tire. The amount of partially crosslinked natural rubber used in a tread compound depends upon the extent of crosslinking in the natural rubber, the non-crosslinked remainder being virgin latex.

Tire tread compounds comprising partially crosslinked natural rubber

A method for processing an elastomer comprising mixing 100 parts by weight of an elastomer having olefinic unsaturation with from 0.05 to 10 phr of a hydrated zinc-sodium thiosulfate. The hydrated zinc-sodium thiosulfate may be used in place of in whole or in part for conventional adhesion promoting cobalt compounds.

Rubber composition containing hydrated zinc-sodium thiosulfate

This invention relates to the discovery that esters of aminobenzoic acid, when used as a replacement in whole or in part of conventional cobalt materials, maintains the rubber-to-wire adhesion properties.

Wire coat compound containing esters of aminobenzoic acid

The present invention relates to a silica-filled rubber composition reinforced with a combination of silica and a mixture of two defined carbon blacks and to pneumatic tires having treads comprised of such rubber composition.

Silica-filled rubber composition containing two different carbon blacks

This invention relates to the discovery that aminobenzylamine, when used as a replacement in whole or in part of conventional cobalt materials, improves the rubber-to-wire adhesion properties.

Rubber compound containing aminobenzylamine

The present invention relates to a rubber composition reinforced with a combination of silica and defined carbon black and to pneumatic tires having treads comprised of such rubber composition. The reinforced rubber composition comprises in one aspect, at least one elastomer, defined carbon black, precipitated silica and at least one silica coupling agent.

Rubber composition and tire with tread thereof

The present invention relates to a heterogeneous silica/carbon black-filled rubber compound and a process for making the same. The rubber compound is characterized by containing silica, two different carbon blacks and two different rubbers. One of the carbon blacks is selectively dispersed in one rubber along with the silica and the other carbon black is dispersed in another rubber. The two rubber compounds are then mixed to form a heterogeneous rubber compound.
