Abstract: A process for coating particles of an expanded thermoplastic elastomer involves a1) bringing the particles into contact with a water-based binder, resulting in at least partly coated particles, and a2) drying the coated particles. A process for the preparation of a shaped body involves b) coating the particles of the expanded thermoplastic elastomer, wherein before a2) the particles are brought into the shape of the shaped body, or wherein after a2) the particles are brought into the shape of the shaped body and contacted with a solvent, preferably a water-based solvent, or by subjecting the particles to heat. A shaped body is obtainable by such processes. A water-based binder is useful for the preparation of a shaped body, wherein the shaped body is formed by particles of an expanded thermoplastic elastomer and wherein the particles are at least partly coated with the water-based binder.

Abstract: A polyurethane, in particular a thermoplastic polyurethane, is obtainable or obtained by reacting at least a polyisocyanate composition and a polyol composition. The polyol composition contains at least one polyester diol or polyether diol, having a number-average molecular weight in the range from 500 to 3000 g/mol, and at least one polysiloxane having two terminal isocyanate-reactive functionalities selected from a thio group, a hydroxyl group, and an amino group. A process can be used for preparing this polyurethane, and a molded body containing the polyurethane is useful.
