An ultra-light and super flexible material
TR90 (plastic titanium) is a kind of memorable polymer material. It is the most popular ultra-light frame material in the world. It has the characteristics of super toughness, abrasion resistance, low friction coefficient and so on. It can effectively prevent the damage to the eyes and face caused by the breakage and friction of the mirror frame in the movement. Because of its unique molecular structure, good chemical resistance, it is not easy to deform in high temperature environment. It can withstand high temperature of 350 degrees in a short time and is not easy to melt and burn.
The release of chemical residues is in line with European requirements for food grade materials. TR90 lens surface lubrication, density 1.14-1.15, put in brine floating, lighter than other plastic spectacles frame, less than half of the weight of the plate frame, is 85% of nylon material, can reduce the burdens of the nose and ears, suitable for young people. The products made of TR90 are wear-resistant, chemical resistant, solvent resistant, weather resistant, non-combustible and heat-resistant. TR90 is a memory polymer material. It is resistant to deformation index 620kg/cm2 and is not easy to deform.
