  • Patent number: 10899870
    Abstract: The thermoplastic polyurethane (TPU) compositions described herein have a very good snap back properties (also called rebound resilience) while still maintaining a good combination of other properties, including hardness, low-temperature flexibility, abrasion resistance, weather-ability, low density, or any combination thereof. This combination of properties make the TPU compositions described herein useful materials for applications where polyamide copolymers (COPA) and/or polyether block amide (PEBA) materials have traditionally been used over TPU.

  • Publication number: 20200216706
    Abstract: Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.

  • Publication number: 20190352446
    Abstract: An article is prepared by injection molding, wherein the article is formed from a hydrophilic thermoplastic polyurethane composition, wherein the thermoplastic polyurethane composition comprises the reaction product of a hydroxyl terminated polyol intermediate component, an aliphatic isocyanate component, and, optionally, a chain extender component. For injection molding, the hydrophilic thermoplastic polyurethane has a crystallization temperature measured by dynamic scanning calorimetry of at least 75° C.

  • Publication number: 20070012704
    Abstract: A blow molded case is disclosed generally comprising a double wall, blow molded base portion having inner and outer case walls, and a lid portion connected to the base portion such that the lid, when in a closed position, at least partly covers the inner case wall of the base portion, which accommodates a first object. The outer wall of the base portion has a hole for receiving a second object, such as a drawer or other receptacle. In certain embodiments, the hole is a punched hole, created by extending a punch through a sidewall of the base portion substantially perpendicular to the parting line thereof. In certain embodiments, the sidewall is non-planar, and in some embodiments, the sidewall includes a recess adjacent the hole for easily gripping the second object.
