  • Thermoplastic polyurethane composition with high mechanical properties, good resistance against UV radiation and low blooming and fogging
    Publication number: 20230250219
    Abstract: A composition contains thermoplastic polyurethane, which is the reaction product of a pentamethylene diisocyanate, a polycarbonate diol, and a chain extender. The composition is useful for producing articles. A production process for producing a filled composition involves adding glass to the composition. Articles can be derived from the composition and the filled composition.

  • High-strength eTPU
    Publication number: 20220033609
    Abstract: Foamed pellets contain a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition (IC), containing at least one aliphatic diisocyanate having a number-average molecular weight of less than 200 g/mol, at least one chain extender (CE1), and a polyol composition (PC). A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.
