Patent number: 9731438Abstract: 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.Type: GrantFiled: April 17, 2012Date of Patent: August 15, 2017Assignee: GATES CORPORATIONInventors: Yahya Hodjat, Yuding Feng, Kathy Lambrinos

Patent number: 9708461Abstract: A method for preparing a “predispersion” of carbon nanotubes in a wax or wax blend involving melt-mixing, cooling and grinding the blend, preferably multiple times. The wax predispersion may provide particularly improved dispersion of single-wall nanotubes in ethylene-?-olefin elastomer compositions, resulting in improved reinforcement from the SWCNT. The improved elastomer compositions may show simultaneous improvement in both modulus and in elongation at break. The inventive elastomer compositions may be formed into useful rubber articles.Type: GrantFiled: April 2, 2014Date of Patent: July 18, 2017Assignee: Gates CorporationInventor: Donald J Burlett
