Low temperature impact resistant, easily flowing, thermoplastic polyurethane elastomer compositions, a process for their preparation and their use |
摘要 |
The present invention deals with low temperature impact resistant, easily flowing, thermoplastic polyurethane elastomer compositions, comprising: A) 5-95 parts by weight of at least one thermoplastic polyurethane elastomer (A) having a Shore A hardness less hah 95; and B) 95-5 parts by weight of at least one thermoplastic polyurethane elastomer (B) having a Shore A hardness greater than 98, whereby the parts by weight of (A) and (B) total 100 parts by weight; and C) 0-60 weight percent based on the weight of (A) and (B) of a reinforcing filler. The products are prepared by melting together polyurethane elastomers (A) and (B) at temperatures of from 140 DEG -250 DEG C., preferably in an extruder, and are most preferred for the preparation of ski boots and injection molded articles for motor vehicles.
