Aliphatic thermoplastic polyurethanes, process for their preparation and their use
摘要
Thermoplastic polyurethane has an abrasion resistance and elongation at break at least 60% of the initial values after storage in heat and at least 80% after hydrolysis storage at 80 degrees C for 7 days, a Tg of at most -50 degrees C and a Shore A hardness of 70-95. Thermoplastic polyurethane (PU) has an abrasion resistance and elongation at break at least 60% of the initial values after storage in heat and at least 80% after hydrolysis storage at 80 degrees C for 7 days, a Tg of at most -50 degrees C and a Shore A hardness of 70-95. Independent claims are included for the continuous production of the above PU by mixing the polyol(s) and chain extender and mixing with diisocyanate(s) within 5 s at 60-50 degrees C and optionally granulating and molded articles made from the above PU.
