Description
Compared with nylon materials, TR-90 frames have the following characteristics:
1. Light weight: about less than half of the weight of the plate frame, 85% of the nylon material, reducing the burden on the bridge of the nose and ears, making it lighter and more comfortable to wear.
2. Bright colors: more vivid and outstanding than ordinary plastic frames.
3. Impact resistance: more than twice that of nylon material, ISO180/IC: 125kg/m2 elasticity, to effectively prevent eye damage due to impact during sports.
4. High temperature resistance: 350 degrees high temperature resistance in a short time, ISO527: anti-deformation index 620kg/cm2. Not easy to melt and burn. The frame is not easy to deform and discolor, so that the frame can be worn longer.
5. Safety: No chemical residues are released, which meets European requirements for food-grade materials.
The material of TR90 is much more expensive than other PC, cp and other spectacle frame materials, and the production process is stricter, so the price of TR90 spectacle frame is several times more expensive than others.
