Publication number: 20040176512Abstract: The invention is the manipulation of the zinc oxide content and sulfur content of nitrile butadiene rubbers and selected vulcanization conditions that can be achieved economically with common production facilities. The manipulation of these components affects the relaxation property of gloves formed by this material. Produced are gloves that have a relaxation property, higher than 50%, and a low modulus (approximately 3 Mpa). The glove maintains decent ultimate tensile strength (>20 Mpa) and elongation (>500%). The glove is produced by a vulcanization process, which lasts from 5 to 60 minutes at temperatures ranging from 300° F. to 400° F. The tensile strength and elongation are well above the ASTM requirements for medical gloves. The current ASTM requirements are ASTM D412-92. Thanks to sufficient vulcanization, the films produced provide satisfactory protection from viral penetration. The tearing strength is also better because of the lower modulus.Type: ApplicationFiled: January 13, 2004Publication date: September 9, 2004Inventor: Jian Tao

The pigment dispersants according to the invention are particularly useful for dispersing concentrated ZnO slurries having a ZnO content of up to about 70% and in slurries containing ZnO in the presence of TiO2.Type: ApplicationFiled: October 2, 2002Publication date: July 31, 2003Inventors: Bruce L. Matta, Ronald W. Broadbent, Grannis S. Johnson, Michael S. Wiggins

Patent number: 6583211Abstract: A moldable heterogeneous composite material has a continuous plastic phase (30) and a discrete phase of unground rubber (20) dispersed in the continuous phase. The composite material can be formed from thermoplastic or thermosetting materials and pieces of rubber from used tires. The composite material of the present invention can be molded in a process having the steps of providing a flowable melt of plastic material (50), providing unground rubber pieces (70), mixing the plastic material with the rubber pieces to form a composite material, and molding the composite material into an article (10) having a desired shape. Molded articles formed from the composite of the present invention have high rigidity and good durability.Type: GrantFiled: December 12, 2000Date of Patent: June 24, 2003Inventor: Thomas A. Wayts

Patent number: 6576697Abstract: A malleable high density polymer material having a high density metal component and a polymer phase consisting of a rigid or hard component, and an elastomeric modifier for the hard component, and where the elastomeric component is chosen from one of several narrow molecular weight distribution ethylene/alpha-olefin elastomers. One advantage of the present invention is to achieve a surprisingly malleable, high density material that has unusual melt properties which may be used as a lead substitute in the making of for example, projectiles, shot, or angling weights. Another advantage of the present invention is to provide a lead substitute that is non-toxic.Type: GrantFiled: September 2, 1999Date of Patent: June 10, 2003Inventor: Thayer A. Brown, Jr.

Patent number: 6573322Abstract: An electroconductive resin composition which exhibits excellent moldability and electric conductivity, and is produced at low costs. The electroconductive resin composition contains a zinc-based metal powder, low melting metal which melts upon molding, and thermoplastic resin. The zinc-based metal powder having a large surface area captures the molten low melting metal to prevent the phase separation thereof from both the resin and zinc-based metal powder. The zinc-based metal powder has a round configuration, as compared to that of fiber so as not to damage the fluidity of the resin greatly. Thus, the resultant electroconductive resin composition is excellent in moldability, and can be produced at low costs.Type: GrantFiled: March 10, 1999Date of Patent: June 3, 2003Assignee: Togo Seisakusho CorporationInventors: Kazutoshi Sakakibara, Takashi Nakashima, Minoru Kaneko, Masatoshi Harada

Publication number: 20030099775Abstract: A high temperature resistive coating composition includes a pigmenting component, a binder component, and a hardening agent. The pigmenting component includes a spinel of the formula AB2O4, in which A is selected from the group consisting of Mg, Fe, Zn, Mn, Cu and Ni, or a combination thereof, and B is selected from the group consisting of Al, Fe and Cr, or a combination thereof. The binder component of the high temperature resistive coating is preferably a polysiloxane material, such as a silicon resin. Moreover, the hardening agent of the high temperature resistive coating includes a finely powdered material selected from the group consisting of diamond powder, BN, WC, SiC, Al2O3, AlN and SiO2. The resistive coating may be advantageously used for coating the interior of a self-cleaning oven, an oven rack, burner grates, and the like, particularly due to its ability to withstand high temperatures.Type: ApplicationFiled: November 29, 2001Publication date: May 29, 2003Applicant: Maytag CorporationInventor: Timothy L.
