What is a TR90 eyewear frame? TR-90 (plastic titanium) is a type of memory polymer material that is currently the most popular ultra-lightweight frame material in the international market. It has exceptional toughness, resistance to impact and wear, and a low coefficient of friction. These characteristics effectively prevent injuries to the eyes and face during sports due to broken frames or friction. Due to its unique molecular structure, it has excellent resistance to chemicals and is less likely to deform in high-temperature environments. It can withstand temperatures up to 350 degrees within a short period of time without melting or burning. There are no chemical residues released, meeting the requirements for food-grade materials in Europe. Now let's take a look at the advantages of TR90 glasses provided by VisionEyeWear compared to other glasses.
Firstly, compared to nylon material eyeglass frames, TR-90 material eyeglass frames have the following characteristics: 1. Lightweight: About half the weight of plastic eyeglass frames, 85% of nylon material, reducing the burden on the bridge of the nose and ears, making wearing more lightweight and comfortable. 2. Vivid colors: The colors of the plastic eyeglass frames are more vibrant and striking than those of ordinary plastic frames. 3. Impact resistance: More than twice that of nylon material frames, ISO180/IC: >125kg/m2 elasticity, to effectively prevent eye injuries caused by impacts during sports. 4. High-temperature resistance: Can withstand high temperatures of up to 350 degrees within a short period, ISO527: Anti-deformation index 620kg/cm2. It is not easily melted or burned. The frame is not easily deformed or discolored, making the frame more durable to wear. 5. Safety: No chemical residue release, meets the requirements of European food-grade materials. Furthermore, the material of TR90 is much more expensive than other types of plastic, such as PC or CP, and the manufacturing process is also more stringent. Therefore, the price of TR90 eyewear is often several times higher than that of other types. The surface of TR90 eyeglass frames is lubricated, with a density of 1.14-1.15. They float in salt water and are lighter than other plastic eyeglass frames, about half the weight of the plate frame and 85% of nylon material, which can reduce the burden on the bridge of the nose and ears. It is suitable for teenagers. It is very wear-resistant, has good anti-chemical properties, good solvent resistance, good weather resistance, is not easy to burn, and can withstand high temperatures. Moreover, it is a memory polymer material with an anti-deformation index of 620kg/cm2, which is not easy to deform. Because the TR90 material eyeglass frame has large elasticity, strong toughness, is not easy to break, and has strong strength, it does not break, so it has a high safety for sports. Moreover, it is very resistant to impact: more than twice that of nylon material, ISO180/IC: >125kg/m2 elasticity, to effectively prevent the damage to the eyes during the movement due to impact. There is no chemical residue release, which meets the requirements of European food-grade materials.
