Flexible Kids Art Frame Acetate eyewear JM22407

TR-90 (plastic titanium) is a kind of polymer material with memory, is currently the world's most popular ultra-light optical frame material, with super toughness, crash-wear resistance, low friction coefficient of characteristics, can effectively prevent in the movement, due to the breakage of the frame, friction on the eyes and face caused by damage. Due to its specific molecular structure, good chemical resistance, it is not easy to deform in a high temperature environment, can withstand 350 degrees high temperature in a short time, and is not easy to melt and burn. No chemical residue release, in line with European requirements for food grade materials.
