Jiayu Product Knowledge: TR-90
TR-90 is a polymer material with memory properties. It is currently the most popular ultra-light frame material in the world. It has the characteristics of super toughness, impact resistance and abrasion resistance, and low friction coefficient. It can effectively prevent, The damage to the eyes and face caused by the fracture of the frame and friction. Because of its specific molecular structure, it has good chemical resistance, is not easy to deform in a high temperature environment, can withstand 350 degrees in a short time, and is not easy to melt and burn.
TR-90 has no chemical residue release and meets European requirements for food-grade materials. The TR90 frame has a lubricating surface with a density of 1.14-1.15. It will float when placed in salt water. It is lighter than other plastic frames, less than half the weight of the plate frame, and 85% of the nylon material. It can reduce the burden on the bridge of the nose and ears. It is suitable for teenagers. Products made of TR90 material have good wear resistance, good chemical resistance, solvent resistance, good weather resistance, non-flammability, and high temperature resistance. TR90 is a memory polymer material with an anti-deformation index of 620kg/cm2, which is not easy to deform.
