摘要： A process for producing a vulcanized elastomeric rubber composition that minimizes or eliminates the appearance of discoloration on the surface of the rubber, and the products formed from this process are disclosed. The process includes the incorporation of polar functional groups into the elastomeric rubber by grafting the functional groups onto a compound miscible in the rubber. It is believed that the polar functional groups increase the solubility of the compounds responsible for iridescence and blooming observed in vulcanized rubber and decrease their migration to the rubber surface. Additional techniques for reducing or eliminating undesirable discoloration in rubber are disclosed.

摘要： Vulcanized ethylene-propylene-diene (EPDM) rubbers are disclosed that are particularly suited for use in dynamic applications as a replacement for natural rubber parts. The ethylene-propylene-diene rubbers exhibit excellent thermal and oxidative resistance while displaying tensile strength and dynamic fatigue resistance comparable to similar compounds based on natural rubber. The ethylene-propylene-diene rubbers comprise a high molecular weight EPDM, a processing oil, a carbon black, and a cure system containing sulfur, tetramethylthiuram-disulfide and 2-mercaptobenzothiazole.

摘要： A bonded part with a press-fit, vulcanized rubber member residing in compression between two rigid members and bonded thereto. The rubber member is a laminate with a core layer sandwiched between and bonded to two self-bonding rubber layers. The bonded part may be, for example, a vibration damper, isolator or absorber. The core layer and the self-bonding layers may have the same primary elastomer and cure system type, and the self-bonding layers have an adhesion promoter not present in the core layer. The adhesive layers may be from 0.05 to 1 mm thick or from 5% to 10% of the laminate thickness.The method includes forming a rubber core layer, curing it, applying a rubber adhesive layer on each side to form a laminate, inserting the laminate between two rigid members under compression, and post-curing to form a bonded part. The adhesive layers may be partially cured before inserting.

摘要： A composite article having an elastomeric composition with a blowing agent having an activation temperature and providing at least one structural member defining a fixed gap. The composition is formed below the blowing agent's activation temperature into a solid elastomeric member approximately the thickness of or larger than the gap. The elastomeric member is assembled into the gap, which may place the elastomeric member in a state of compression in the gap. The elastomeric member is then expanded by heating it above the activation temperature. During expansion, the escape of the gas produced is limited to increase the state of compression of the elastomer in the gap by means of confining any free surfaces or by including a platy filler such as nanoclay in the composition.
