WIPO Patent Application WO/2015/046370

A1

This eyewear material contains thermoplastic polyurethane. Under measurement conditions of a 5°C/min rate of rise in temperature and a measurement frequency of 10Hz, the eyewear material has tan δ peaks observed by dynamic viscoelasticity measurement in tensile mode at both less than 0°C and between 0°C and 70°C.
