Abstract
PURPOSE: To obtain a molded polyurethane article having improved hardness and heat resistance stably, industrially and advantageously, by mixing a polyisocyanate compound having a specific molecular weight with a thermoplastic polyurethane resin, and hot molding the resultant mixture.
CONSTITUTION: (A) A previously molten thermoplastic polyurethane resin under heating is mixed with (B) a polyisocyanate compound preferably a reaction product of polytetramethylene ether glycol with hexamethylene diisocyanate, having a molecular weight ≥300 in an amount of preferably 5W20wt% based on the mixture of the components (A) with (B), and the resultant mixture is then extrusion or injection molded. The melting temperature of the component (A) is preferably 190W230°C, and that of the component (B) is preferably 100°C or below.
