Thermoplastic elastomer composition.U.S. patent: 7,105,611 Issued: September 12, 2006 Inventors: Katsuhiko Kimura, Kenji Noda, Hironari Nakabayashi and Taizo Aoyama Assigned: Kaneka Key statement: A thermoplastic elastomer Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. composition is highly flexible while maintaining vibration damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the properties, and has improved permanent compression set. It contains (A) an isobutylene Noun 1. isobutylene - used also in making gasoline components butene, butylene - any of three isomeric hydrocarbons C4H8; all used in making synthetic rubbers butyl - a hydrocarbon radical (C4H9) polymer crosslinked with a hydrosilyl group-containing compound by melt-kneading in the presence of an aromatic aromatic /ar·o·mat·ic/ (ar?o-mat´ik) 1. having a spicy odor. 2. in chemistry, denoting a compound containing a ring system stabilized by a closed circle of conjugated double bonds or nonbonding electron pairs, e.g. vinyl-containing thermoplastic elastomer and an olefinic resin, and (B) an aromatic vinyl-containing thermoplastic elastomer and an olefinic resin. |
