Title:
POLYURETHANE RESIN, METHOD FOR PRODUCING POLYURETHANE RESIN, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2018/207807
Kind Code:
A1
Abstract:
A polyurethane resin which is a reaction product obtained by reacting a polyisocyanate ingredient comprising bis(isocyanatomethyl)cyclohexane with a macropolyol ingredient having a number-average molecular weight higher than 400 but not higher than 5,000. The polyurethane resin has a Shore A hardness of 80 or less, exhibits a storage modulus E' of 1×106 Pa at a temperature which is not lower than 200°C, and has a ratio of the 150°C storage modulus E'15
0 to the 50°C storage modulus E'50, E'150/E'50, of 0.1-1.4.
