The characteristics of [TR90]

Currently the most popular ultra light frame material TR 90 (plastic titanium)， with super toughness， super strength，can be bent arbitrarily， collision resistance wear resistance， low coefficient of friction characteristics， can effectively prevent the in motion， because the frame fracture， the friction caused by damage to the eyes and face. Because of its specific molecular structure， excellent chemical resistance， not easy to deformation in high temperature environment， a short period of time can be resistant to high temperature of 350 degrees， is not easy to melt and burn. No release of chemical residues， consistent with the requirements of the European food grade materials.

Compared with the resin frame []

1， light weight: about half of the plate frame with less weight， is nylon material 85%， reduce the bridge of the nose，ears burden， make more light and comfortable to wear.

2， color: color is more brilliant than ordinary plastic frame well.

3， impact resistant material: nylon is more than 2 times， the ISO180/IC:>125kg/m2 elastic， in order to effectively prevent in motion because of impact damage to the eye that can occur.

4: high temperature resistant， resistant to high temperature of 350 degrees in a short time， ISO527: anti deformationindex 620kg/cm2. Not easy to melt and burn. The frame is not easy deformation is not easy to change color， so that the frames to wear longer.

5， security: no release of chemical residues， consistent with the requirements of the European food grade materials.

The 2010 latest， using splash lens， breathable windproof design， completely according to the Chinese face design，including a lens using the sports glasses top black REVO lens.

Lens: the more thick， PC riot lens impact resistance is stronger.

This paper introduces in detail the product:

Lens material:

PC lens， first used in industrial protection (such as aircraft transparent cabin safety mask， etc.)， material hasexcellent impact resistance. After 90 years， due to the development of science and technology， optical grade PCmaterial was applied， started for advanced optical lens. 0.5CM PC materials can block 20 meters outside the body impact， general PC lens with a hammer is not easy to break.
