Methods for treating a cured inner liner as well as treated, cured inner liners resulting from such methods are disclosed. Also disclosed are tires containing the treated inner liners. The methods include treatment of the lower surface of inner liner surface with a rubber-containing liquid to produce a rubber-containing film thereupon.

A hot press cushioning material includes fluororubber. A composition of the fluororubber includes a fluororubber component, a vulcanizing agent, an acid acceptor, and a dehydrating agent.

A rubber composition comprising: (a) a crosslinking reactive fluorine-containing rubber; (b) a compound represented by the following formula (b-1): and

##STR00001## (c) a compound represented by the following formula (c-1):

##STR00002##

A method for preparing a vulcanizable composition of matter, the method comprising mixing, within a first mixing step, rubber, silica, and silica coupling agent to form a first masterbatch composition, adding nicotinamide to the first masterbatch composition and mixing within a second mixing step to form a second masterbatch composition, and adding a curative to the second masterbatch composition and mixing within a final mixing step.

A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.

The present disclosure relates to a pressure sensitive adhesive foam comprising a rubber-based elastomeric material and at least one hydrocarbon tackifier, wherein the hydrocarbon tackifier(s) have a Volatile Organic Compound (VOC) value of less than 1000 ppm and a Volatile Fogging Compound (FOG) value of less than 1500 ppm, when measured by thermogravimetric analysis according to the weight loss test methods described in the experimental section. The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive foam and uses thereof.

A nanostructured porous catalyst for rubber vulcanization, the catalyst comprising a high surface area.

Provided among other things is an elastomeric article providing a chemical barrier, the article having a layered structure comprising a sequential laminate of: (a) a latex-based elastomeric polymeric barrier layer; (b) a non-reactive tie adhesive resin layer comprising oxo (—(C═O)—) groups; and (c) a polyamide layer; wherein the layered structure has a first side nearest the latex-based elastomeric polymeric barrier layer and a second side; wherein the layered structure is effective to provide a chemical permeation time in excess of 100 minutes pursuant to EN 16523-1:2015 for benchmark solvents of acetone, ethyl acetate and methanol, when applied to the first side, and in excess of 100 minutes for acetone when applied to the second side; and wherein the elastomeric layer is primarily not polyolefin.
