TR material children’s optical glasses frame, universal for boys and girls XH Series

TR90 glasses frame has the characteristics of super toughness, impact resistance and wear resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by breakage and friction of the glasses frame during sports. Because of its unique molecular structure, it has good chemical resistance and is not easily deformed in high temperature environments. It can withstand high temperatures of 350 degrees in a short period of time and is not easy to melt and burn. Moreover, the TR90 glasses frame has a smooth surface and a density of 1.14-1.15. It will float when placed in salt water. It is about half the weight of the plate frame and 85% of the nylon material. It can reduce the burden on the bridge of the nose and ears and is suitable for teenagers. Summary: It has good extrusion resistance and high elasticity. It is a must-have choice for students and athletes.
