Abstract: The present invention relates to a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition, a chain extender, and a polyol composition, wherein the polyol composition comprises at least one polyol (P1) which has a molecular weight Mw in the range from 500 to 2500 g/mol and has at least one aromatic polyester block (B1), wherein the polyol (P1) includes 20% to 70% by weight of the aromatic polyester blocks (B1), based on the overall polyester polyol (P1). The present invention further relates to a process for producing a shaped body comprising such a thermoplastic polyurethane, and to shaped bodies obtainable or obtained by a process of the invention.

Abstract: Described herein is a method for the preparation of a rigid polyisocyanate based foam, including mixing (a) polyisocyanate, (b) at least one compound having at least two hydrogen atoms reactive towards isocyanates, (c) optionally flame retardant, (d) blowing agent, (e) catalyst and (f) optionally further additives, to form a reaction mixture and reacting the reaction mixture to obtain the polyurethane based rigid foam where the compound reactive towards isocyanates (b) includes an aromatic polyetherpolyol (b2) and at least one compound selected from the group consisting of an aromatic polyesterpolyol (b1) and a polyetherpolyol (b3) different from polyether (b2). Also described herein is a rigid polyisocyanate based foam obtained from such a method and a polyol component for the production of a polyisocyanate based foam.
