Recycled elements and/or renewable resources, such as recycled carbon black or recycled carbon black and recycled particulate rubber, are incorporated into a rubber composition. The rubber composition can be used to manufacture tires or various tire components including tire subtreads.
Abstract:
Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).
Abstract:
Provided are a phenol-denatured polyorganosiloxane that is suitable as an organic resin modifier, has a small a platinum metal content, and is little yellowish, a method for producing the same, and an organic resin modifier containing the same. The phenol-modified polyorganosiloxane according to the present invention is a compound of formula (I) that has a platinum metal content of 0.9 ppm or less. The phenol-denatured polyorganosiloxane according to the present invention can be prepared by, for example, subjecting an alkenyl group substituted phenol compound of formula (IV) and a polyorganohydrogen siloxane of formula (V) to a hydrosilylation reaction in the presence of a platinum-based catalyst that is applicable to a homogenous system, and then conducting one or more kinds of filtration procedures selected from the group consisting of filtration with the addition of activated carbon, filtration using an activated carbon-containing filter and filtration using a cationic charge absorption filter, at least once either alone and/or in combination to reduce the platinum metal content to 0.9 ppm or less.
