What is the material of tr90?

Tr90 is a polymer material with memory function. It is a popular ultra-light frame material in the world at present, which has the characteristics of super toughness, impact resistance, wear resistance and low friction coefficient. It can effectively prevent eye and face injuries caused by broken frame and friction during exercise. Because of its special molecular structure, it has good corrosion resistance and is not easy to deform in high temperature environment. It can withstand 350 degrees high temperature in a short time and is not easy to melt and burn.

Characteristics of tr90 material

The surface of TR90 spectacle frame is lubricated, which is lighter than other plastic spectacle frames and 85% nylon material. It can reduce the burden on the nose and ears and is suitable for teenagers. The anti-deformation index is 620kg/cm2, and it is not easy to deform. Moreover, it is very impact-resistant: it is more than twice that of nylon, and the material of TR90 is much more expensive than other spectacle frames such as pc and cp, and the manufacturing process is also strict, so the price of TR90 spectacle frames is several times more expensive than others.
