20090275690 | Articles Comprising Nonpolar Polyolefin and Polyurethane, and Methods for Their Preparation and Use - The adhesion between a low surface energy (i.e., nonpolar) material, e.g., a polyolefin such as polyethylene, and a high surface energy (i.e., polar) material, e.g., a polyester, polyurethane, polycarbonate or polylactic acid, is promoted by blending with the nonpolar material typically from 15 to less than 50 wt % of a diol-based thermoplastic polyurethane (d-TPU), e.g., a polydiene diol-based TPU, based on the combined weight of the nonpolar material and the d-TPU. The promoted adhesion allows for the effective painting, printing, over-molding or HF-welding of a nonpolar substrate, e.g., a polyolefin film, with a polar coating, e.g., a paint, ink, etc. Aqueous dispersions can also be made from the blend of nonpolar material and d-TPU. | 11-05-2009 |
20100028568 | Polyurethane Compositions and Articles Prepared Therefrom, and Methods for Making the Same - The invention provides a composition comprising the following: at least one olefin-based polymer, at least one halogenated ethylene-based polymer, or at least one elastomer rubber; at least one thermoplastic polyurethane; and at least one polydiene- or polydiol-based polyurethane. These compositions are well-suited for promoting the adhesion between polar (for example, polyester, polycarbonate and polylactic acid) and non-polar materials and for the manufacture of, among other things, films, fibers, sheets and tie layers, tubes, adhesives, dispersions, protective apparel, footwear, coatings, laminates and foams. | 02-04-2010 |
20100029827 | POLYOLEFIN COMPOSITIONS AND ARTICLES PREPARED THEREFROM, AND METHODS FOR MAKING THE SAME - The invention provides a composition comprising at least one olefin multi-block interpolymer; at least one functionalized olefin-based polymer; and optionally at least one thermoplastic polyurethane. The invention also provides for articles prepared from the inventive compositions and for methods for making the same. | 02-04-2010 |
20100055358 | Polyurethane Compositions and Articles Prepared Therefrom, and Methods for Making the Same - The invention provides a composition comprising the following: at least one olefin multi-block interpolymer, at least one thermoplastic polyurethane, and at least one polydiene-based and/or polydiol-based polyurethane. These compositions are well-suited for promoting the adhesion between polar (for example, polyester, polycarbonate and polylactic acid) and non-polar materials and for the manufacture of, among other things, films, fibers, sheets and tie layers, tubes, adhesives, dispersions, protective apparel, footwear, coatings, laminates and foams. | 03-04-2010 |
20100087579 | Magnesium Hydroxide-Based Flame Retardant Compositions Made Via In-Situ Hydration of Polymer Compounds Comprising Magnesium Oxide - Magnesium oxide (MgO) compounded into a polymer can subsequently be hydrated in-situ within the polymer to form magnesium hydroxide. In the case of silane-based or peroxide-based crosslinkable resins, the MgO hydration and polymer crosslinking can be done in a single process step, or in sequential steps. In the case of non-crosslinkable compounds, hydration can be carried out after compounding (no crosslinking step). In all cases, steam CV, sauna, or hot water bath are options for hydration. This approach enables preparation of polymer compounds that are flame retarded with metal hydrates yet free of the traditional limitations posed by shelf instability, extrusion scorch, undesired dehydration, and processing temperature limitations posed by metal hydrates. | 04-08-2010 |
