TR-90 (Plastic titanium) is a polymer material having a memory, and is currently the most popular ultra-light frame material PA12, with super toughness, crashworthiness wear, low friction coefficient, which can effectively prevent the movement , because the frame breaking, causing friction on the eyes and facial injuries. Its specific molecular structure, good chemical resistance PA12 plastic reinforced in high temperature environment is not easy deformation, a short 350 degree heat resistant, easy to melt and burn. No chemical residue release, in line with European requirements for food grade material. TR90 frames surface lubricity, density 1.14-1.15, will float on the salt PA12 transparent nylon, plastic frames other than light, about half the plate frame with less weight, 85% nylon material, can reduce the nose, ears burden, for young people to use. It is abrasion resistance, chemical resistance, solvent resistance, weather resistance, non-flammable, high temperature. And it is a memory polymer material, the resistance to deformation index 620kg / cm2, easy to change. Because frames TR90 material elasticity, toughness, not broken, high strength, not broken, and therefore have a sports safety. And it is very resistant to impact: nylon material is more than 2 times, ISO180 / IC:> 125kg / m2 flexibility to effectively prevent injury during exercise due to an impact on the eye produced. By TR90 frames made out of the box the physical picture taken as follows: PA12 qualities enhanced 15-30% fuel-grade plastic injection group PA12 eyeglass frame material for automotive parts, aviation parts, electronics and other fields, this plastic has a high toughness and hardness, resistance, low friction coefficient, is an excellent overall performance are more plastic! Therefore favored by all walks of life! PA12 enhanced 15-30% physical picture taken as follows: PA12 plastic, plastic Masahiro integrity management (certified), PA12 by Masahiro Plastics Co., Ltd., Dongguan City.
