Publication number: 20040249051Abstract: An acrylic rubber composition in which the base material is an acrylic rubber comprising monomer units of ethyl acrylate, n-butyl acrylate, and cure site monomer, with a ratio (B/A) of the amount of n-butyl acrylate (B) with respect to ethyl acrylate (A) of 1.0 or less by weight. A heat-resistant hose having a layer of this acrylic rubber composition as the innermost layer. The above constitution of the invention provides the acrylic rubber composition effective for preventing aluminum fixing while retaining the material properties of acrylic rubber and its excellent characteristics. The present invention also provides a heat-resistant hose using this acrylic rubber composition at the surface which is to be fitted with an aluminum member.Type: ApplicationFiled: March 8, 2004Publication date: December 9, 2004Inventors: Masashi Noda, Shinobu Kanbe, Hiroyoshi Mori, Motohide Nishimura

Patent number: 6828387Abstract: The invention disclosed herein relates to an improved process for making elastomeric polyisoprene articles. In particular, the process of the invention is a system which produces synthetic polyisoprene articles exhibiting tensile strength properties similar to that of solvent-based processes using natural rubber latex. The process comprises an accelerator composition at the pre-cure stage comprising a dithiocarbamate, a thiazole and a guanidine compound. In a preferred embodiment, the accelerator composition comprises zinc diethyldithiocarbamate (ZDEC), zinc 2-mercaptobenzothiazole (ZMBT) and diphenyl guanidine (DPG), in conjunction with a stabilizer, such as sodium caseinate. The invention also includes an elastomeric polyisoprene product made by the process, such as a surgeon's glove.Type: GrantFiled: March 12, 2002Date of Patent: December 7, 2004Assignee: Allegiance CorporationInventors: Shiping Wang, Yun-Siung Tony Yeh, Randell Wenig, Wong Weicheong

Patent number: 6793996Abstract: An outsole (1) has a body (2), a spike (3), a first projected portion (4), and a second projected portion (5). The spike (3) has a disk-like portion (7) and a pin (8). The disk-like portion (7) and the pin (8) are composed of a rubber-molded material. The rubber-molded material contains 30 wt % or more of polybutadiene or acrylonitrile-butadiene copolymer as a rubber component thereof. The JIS-C hardness of the rubber-molded material is set to the range from 35 to 95 both inclusive. The cutting-time elongation of the rubber-molded material is set to 280% or more. The difference (h1−h2) between a projected height (h1) of the spike (3) and a projected height (h2) of the first projected portion (4) as well as the second projected portion (5) is set to the range from 0 mm to 15 mm both inclusive.Type: GrantFiled: July 25, 2000Date of Patent: September 21, 2004Assignee: Sumitomo Rubber Industries, Ltd.Inventor: Ikuko Umezawa
