TR-90 (plastic titanium) is a kind of polymer material with memory. It is the most popular ultra-light spectacle frame material in the world. It has the characteristics of super toughness, impact resistance and wear resistance, low friction coefficient, etc. , damage to the eyes and face due to broken eyeglass frames and friction. Because of its specific molecular structure, it has good chemical resistance and is not easily deformed in a high temperature environment. It can withstand high temperatures of 350 degrees in a short time, and is not easy to melt and burn. No chemical residues are released, meeting European requirements for food-grade materials, and it is also the material with the largest sales volume.
Compared with nylon spectacle frames in Europe and the United States, TR-90 spectacle frames have the following characteristics:
1. Light weight: about half the weight of the acetate frame, and 85% of the nylon material, reducing the burden on the bridge of the nose and ears, making it more comfortable to wear.
2. Bright colors: The colors are brighter and better than ordinary plastic eyeglass frames.
3. Impact resistance: It is more than 2 times that of nylon spectacle frames, ISO180/IC: >125kg/m2 elasticity, so as to effectively prevent eye damage caused by impact during exercise.
4. High temperature resistance: It can withstand high temperature of 350 degrees in a short time, ISO527: deformation resistance index 620kg/cm2. Not easy to melt and burn. The glasses frame is not easy to be deformed and not easy to change color, so that the frame can be worn for a longer time.
5. Safety: no release of chemical residues, in line with European requirements for food-grade materials.
The surface of TR90 glasses frame is smooth and the density is 1.14-1.15. It will float in salt water. It is lighter than other plastic glasses frames, about half of the weight of the plate frame, and 85% of the nylon material, which can reduce the burden on the bridge of the nose and ears, suitable for young people. . It is wear-resistant, chemical-resistant, solvent-resistant, weather-resistant, non-flammable, and heat-resistant. And it is a memory polymer material, the anti-deformation index is 620kg/cm2, and it is not easy to deform. Because the spectacle frame of TR90 material has high elasticity and toughness, it is not easy to break, has high strength and does not break, so it has sports safety. And it is very resistant to impact: more than 2 times that of nylon material, ISO180/IC: >125kg/m2 elasticity, to effectively prevent eye damage due to impact during exercise. No chemical residues are released, meeting European requirem
