Filed:

Jun 30, 2004

Appl. No.:

10/880733

Inventors:

Xiaofeng Shaw Yang - Mauldin SC, US
Chris Kerechanin - Greer SC, US

Assignee:

Michelin Recherche et Technique S.A.

International Classification:

B29C 35/02

US Classification:

425 40, 249 79

Abstract:

An apparatus for transferring heat into a product, such as a tire, formed at least in part by molding is provided. The apparatus includes a mold that has a central axis with a forming surface disposed radially outward from the central axis. A heating conduit is included and is at least partially located radially outward from the forming surface of the mold. The heating conduit is configured for use with a gas, such as saturated steam, in order to effect heat transfer to the forming surface of the mold. The heating conduit extends helically with respect to the central axis in order to allow condensation formed in the heating conduit to be drained therefrom via the force of gravity. A drainage connector may be in communication with the exit of the heating conduit and have a lower longitudinal axis than the heating conduit to allow condensation to drain more easily therefrom.

Abstract:

A cushion gum for bonding a tire tread to a tire carcass, the cushion gum comprising an essentially unsaturated diene elastomer, between (0.5) and (25) phr of a metal salt of a carboxylic acid and a peroxide curing system. The essentially unsaturated diene elastomer may be, in some embodiments, a highly unsaturated diene elastomer such as, for example, natural rubber.

Appl. No.:

13/510632

Inventors:

Xiaofeng Shaw Yang - Simpsonville SC, US

International Classification:

C08K 3/04
C08L 21/00

US Classification:

524571, 106472

Abstract:

Using a target loading value and target intrinsic properties desired for a rubber formulation, two or more fillers are combined to create a blend having the desired intrinsic properties—i. e. a blend can be created emulating the desired intrinsic properties of a single filler system. In another exemplary aspect, knowing the individual loadings of fillers along with the target values desired for the loading of the blend and its intrinsic properties, individual intrinsic properties for at least one unknown filler that will be used to create the blend can be calculated. The unknown filler can then be identified by comparing the calculated intrinsic properties with the intrinsic properties of known fillers. The method allows e.g.) a manufacturer to blend a variety of suitable fillers while maintaining a more limited inventory of fillers than would otherwise be required for multiple rubber formulations.

International Classification:

C08L 7/00
C08K 5/41

US Classification:

523156

Abstract:

Tire treads, especially tire treads for aircraft or for heavy vehicles, formed from a material that is based upon a cross-linkable rubber composition, the cross-linkable rubber composition comprising, per 100 parts by weight of rubber, between 40 phr and J 00 phr of a polyisoprene rubber, between 0 and 60 phr of a highly unsaturated diene rubber and between 1 phr and 25 phr of a polylerpene resin having a glass transition temperature of between 50 C. and 120 C. The rubber composition further includes between 0.1 phr and 10 phr of a poly-thiosulfate anti-reversion agent having the formula: MOS—S—X—S—SOM wherein X is an alkylene radical or a radical comprising two or more alkylene units, pairs of which units being linked through an oxygen or a sulfur atom, through a group SO—, —NH—, —NH—, —NlC-alkyl)- or —COO—, or through an arylene or cycloalkylene radical and M is a metal.

US Classification:

524575, 5245755

Abstract:

A rubber composition comprising a metal salt of a carboxylic acid used as a curing agent, a highly unsaturated dieene rubber, a filler and a sulfur vulcanization system of between 0.5 phr and 8 phr of sulfur and at least one vulcanization accelerator. Particular embodiments may further include between 1 phr and 6 phr of a metal salt of a carboxylic acid that increases a tear index of the cured elastomer composition by at least 50 percent as compared to a similar cured elastomer composition, such similar cured elastomer composition being different in composition only in that it (1) lacks the metal salt of a carboxylic acid and (2) has an increased amount of the sulfur vulcanization system at about the same sulfur to accelerator ratio to maintain a 10% modulus of elongation at 23 0C to within 15% of the modulus of the cured rubber composition.
