Provided is a rubber member that can, when used in a rubber article such as a tire, improve the on-ice performance of the rubber article. A rubber member comprises a nanomaterial, wherein the nanomaterial has a major axis of less than 100 nm in the case of being non-fibrous or a minor axis length of less than 100 nm and a major axis length of less than 1000 nm in the case of being fibrous, and has a content of a polar group of 100 mg/kg or more.

A carbon nanotube (CNT)/polymer film or CNT/polymer composite structure containing CNTs, arranged uniformly in a randomly oriented distribution in the polymer matrix. The CNT sheet is manufactured by applying a highly dispersed CNT-polymer-solvent suspension, mixed using ultrasonication, over a carrier, using a coating process, and drying to form the CNT/polymer film. The CNT film is useful in making CNT composite laminates and structures having utility for electro-thermal heating, deicing, shielding for wire & cable, thermal interface pads, energy storage, heat dissipation, conductive composites, antennas, reflectors, and electromagnetic environmental effects (E3), such as lightning strike protection, EMP protection, directed energy protection, and EMI shielding in a variety of form factors such as sheets, roll stocks, and tapes.

A rubber composition in which a transfer roller with lower resistance than in the related art is able to be formed without increasing a blending ratio of epichlorohydrin rubber, a transfer roller including the rubber composition, and an image forming apparatus having the transfer roller incorporated therein are provided. The rubber composition is obtained by blending rubbers including at least one of NBR, SBR, and BR and epichlorohydrin rubber with a crosslinking component, a foaming component, and 3 to 50 parts by mass aluminum silicate with respect to 100 parts by mass of the total amount of rubbers. A transfer roller includes a roller main body formed by extrusion-molding the rubber composition in a tubular shape and foaming and crosslinking the rubber composition. The image forming apparatus includes the transfer roller incorporated therein.

This invention relates generally to vulcanization compounds and relates more specifically to vulcanization compositions with reduced allergenic potential that include accelerator compositions for vulcanizing elastomeric articles. Vulcanization compositions are disclosed that include a single fugitive dihydrocarbyl xanthogen polysulfide accelerator and a single aldehyde-aniline condensate accelerator.
