TR-90 (Plastic Titanium) is a polymer material with memory properties. It is the most popular ultra-light frame material in the world. It has characteristics such as super toughness, crashworthiness, wear resistance, low friction coefficient, etc., which can effectively prevent movement. Due to broken frames, friction and damage to the eyes and face.
TR90 spectacle frame surface lubrication, density 1.14-1.15, will float on salt water, lighter than other plastic spectacle frames, less than half of the weight of the plate frame, 85% of nylon material, can reduce the nose, ear burden, suitable for young people to use . It is very wear-resistant, chemically resistant, solvent-resistant, weather-resistant, non-flammable, and resistant to high temperatures. And it is a memory polymer material, anti-deformation index 620kg/cm2, not easy to change. Because the frame of the TR90 material is elastic, strong in toughness, difficult to break, strong, and does not break, it has sports safety. And it is very resistant to impact: it is more than 2 times nylon material, ISO180/IC: >125kg/m2 elasticity, in order to effectively prevent the impact on the eye caused by sports. No chemical residue release, in line with European requirements for food grade materials. The material of TR90 is much more expensive than other spectacle frames such as pc and cp, and the manufacturing process is also quite strict. Therefore, the price of TR90 spectacle frames is several times more expensive than other spectacle frames.
advantage
TR-90 full name is "Grilamid TR90" Originally a transparent nylon material developed by Swiss EMS company, because of its various properties suitable for frame production, it has been widely used in the field of optics in recent years (in fact, EMS company also has a call TR-55, but its characteristics are not suitable for frame products). The TR90 is both an EMS company's nylon 12 (PA12) and has the following advantages:
1, light weight: about less than half the weight of the plate box, nylon material is 85%, reducing the nose, ears burden, so that more light and comfortable to wear.
2, colorful: better than ordinary plastic frame color more brilliant.
3, impact resistance: is more than 2 times nylon material, ISO180/IC:> 125kg/m2 elasticity, in order to effectively prevent the impact of the eye caused by sports injuries.
4, high temperature resistance: a short time can withstand high temperature of 350 degrees, ISO527: anti-deformation index 620kg/cm2. Not easy to melt and burn. Frames are not easily deformed and discolored, allowing the frames to wear longer.
5. Safety: No release of chemical residues, in line with European requirements for food grade materials.
