  • Patent number: 6992134
    Abstract: The present invention relates to a polyurethane surface and more specifically to a polyurethane surface derived from the catalyzed reaction of equivalent volumes of a polyisocyanate component and an active hydrogen component. The two-component system achieves optimal gel time and cure response for application as an athletic surface having an isocyanate index between about 105 and 115. Moreover, the present invention achieves these results with a 1:1 by volume two-component system, which minimizes mixing errors during application of the surface.

  • Patent number: 6943130
    Abstract: A method for producing a fabric-elastomer sandwich, consisting in providing a fabric with at least minute gaps between its fibers, in placing the fabric on a mold having at least resting portions for the fabric and at least regions which are recessed with respect to the resting portions, in applying an elastomer to the side of the fabric that lies opposite to the side directed toward the mold, in applying pressure to make the elastomer flow through the minute gaps located at the recessed regions in order to fill the recessed regions with the elastomer, and in extracting the sandwich from the mold.

  • Patent number: 6896964
    Abstract: Treated rubber is made from ground rubber and a polyurethane resin. Products made by mixing treated rubber with additional polyurethane resin, molding and curing the polyurethane have higher tensile strengths and/or elongations than similar products made from untreated rubber. The method using treated rubber uses less polyurethane binder to produce products of equivalent strengths. The molding time is also reduced because of the reduced amount of polyurethane binder used.

  • Publication number: 20040132363
    Abstract: A tear resistant seal made from a recyclable multilayer structure that consists of an oriented polymer film layer a thermal bonding polymer layer on the oriented polymer layer inner surface substantially coextensive thereto, and a reinforcing scrim polymer layer also having an inner surface adjacent and substantially coextensive with the thermal bonding polymer layer. The polymer film layer and the bonding polymer layer are co-extruded layers having a chemical composition that permits recycling without separating the layers. The scrim layer also has a similar chemical composition, permitting recycling following lamination, thereby permitting the recovery of waste material during production runs by the simple recycling of the complete laminated structure.

  • Patent number: 6716777
    Abstract: A fabric structure is constructed having a fabric base sheet, a viscidity layer, a polymeric back layer, and a protective layer. The polymeric back layer is prepared from SBC (styrenic block copolymer) for the advantage of low specific gravity and preventing the drawback of PVC or the like that pollutes the environment when disposed off. The protective layer is prepared from PU series or modified SBC (styrenic block copolymer) series agent. When the fabric structure used to make a bag, the front surface of the fabric base sheet is disposed outside the bag and the surface of the protective layer is disposed inside the bag.

  • Patent number: 6638587
    Abstract: The invention disclosed herein relates to an elastomeric article, such as a glove, containing an elastomeric material such as latex and a coating layer formed from an aqueous dispersion containing a composite of a silicone-modified polymer, e.g., a silicone-modified polyurethane, and silicone resin particles integrated therein. The interaction between the silicone groups on both the polymer and particles produces enhances binding effectiveness of the particles to the material. Gloves and other articles made in accordance with the invention contain a microroughened skin-contacting surface and exhibit a reduced coefficient of friction and increased lubricity, thereby enhancing the donning properties thereof.
