TR spectacle frame surface lubrication, density 1. 14- 1。 15, floating in salt water, is lighter than other plastic spectacle frames, about half the weight of the frame, and nylon material accounts for 85%, which can reduce the burden on nose and ears and is suitable for teenagers. It is wear-resistant, chemical-resistant, solvent-resistant, weather-resistant, nonflammable and high temperature-resistant. No chemical residue is released, which meets the European requirements for food-grade materials.
Moreover, it is a memory polymer material with an anti-deformation index of 620kg/cm2, which is not easy to deform. Because the glasses frame made of TR90 has good elasticity and toughness, it is not easy to break, strong and unbreakable, and it has sports safety. But also very impact-resistant, and can effectively prevent the eye injury caused by impact during exercise.
Tr frame is an ultra-light frame material popular in the world at present. In fact, TR materials can be used not only as eye frames, but also in automobile, electrical appliances, electronics, industry, packaging, medical care and other fields. And it can also be used as lighting equipment, so we say its application is quite extensive.
