Described is a thermoplastic molding composition comprising: a) 0.05 to 1.5 wt. %, with respect to the entire molding composition, of a fatty acid amide ester wax; b) 0.5 to 10 wt. %, with respect to the entire molding composition, of a silica selected from natural silica, synthetic silica and mixtures thereof; c) 0 to 1 wt. %, with respect to the entire molding composition, of a montan wax; and d) at least one thermoplastic elastomer. Also described are a method of preparing the thermoplastic molding composition, and methods of preparing articles from the thermoplastic molding composition.

Thermoplastic elastomer molding compositions with improved processability

The invention relates to an extruded single-layer copolyetherester film with improved permeability to water vapor coupled with favorable mechanical properties, high elasticity and good surface slip so that it does not block on machinery.

Water vapor permeable breathable films and their use

A waterproof and, at the same time, breathable and antistatic film produced without a support by extrusion, the film having a DIN friction coefficient of less than 0.8 and consisting of thermoplastic polyurethane elastomer resins with a melt flow rate, as measured at 190.degree. C. under a load of 10 kg, of at most 70, the soft segment of the elastomer resins consisting of polyethylene oxide and/or containing ethylene oxide reaction products and the relative percentage by weight of the soft segment in the polyurethane resin being between 35% by weight and 60% by weight, based on the total weight of the polyurethane used.

Non-crackling, antistatic polyurethane film with high breathability and

Process for the preparation of translucent matt polyurethane films with a rough surface by extrusion of thermoplastic polyurethane elastomers to flat films or tubular films, characterized in that the extruded film is stored until it has a turbidity of &gt; 15%, measured in accordance with ASTM D 1003, and the two film surfaces are then embossed with the aid of embossing rolls with a different number of grids, each in the range from 20 to 100 grids/cm.sup.2, under a pressure of 5 to 20 bar at temperatures of 130.degree. to 175.degree. C.
