Moldings of thermoplastic polyurethanes with reduced formation veil.

Thermoplastic polyurethane molded products with very low fogging values are obtained by reacting a diisocyanate with a polyol component containing a polyester-polyol with a content of less than 0.2 (preferably less than 0.15) wt.% of 1:1 cyclic esters of a dicarboxylic acid and a diol. Molded products with a condensate value of 2 mg/10 g, according to DIN 75201-B fogging test (16 hours at 120 degrees C), made from thermoplastic polyurethane (TPU) with a similar condensate value. The TPU is obtained from: (A) an organic diisocyanate; (B) a polyester-polyol (20-100, preferably 30-100 wt.%) with a number average molecular weight (Mn) of 600-10000, containing 0.2 (preferably 0.15) wt.% 1:1 cyclic esters of dicarboxylic acid and diol; and polyether-polyol or polycarbonate-diol (0-80 wt.%) with an Mn of 600-10000; (C) a diol or diamine chain extender with a molecular weight of 60-500; optionally with the addition of (D) catalysts; and (E) conventional additives. The TPU is produced with an equivalent ratio of (A):(B) = 1.5:1.0 to 10.0:1.0 and an NCO index of 95-105. An Independent claim is also included for the production of these molded products by processing the TPU by known methods.
