Due to the different materials of the frame, the characteristics of the frame are also different. And the TR eyeglass frames are currently the most popular.

 

 

The introduction of the TR eyeglass frames

 

TR90 is a polymer material with memory and is currently the most popular ultra-light frame material in the world. The full name of TR90 is "Grilamid TR-90". It was originally a transparent nylon material developed by Swiss EMS company. Because of its various properties suitable for the production of frames, it has been widely used in the production of TR 90 frame optical glasses in recent years.

 

The material of high quality TR eyeglass frames is much more expensive than other frame materials. And the manufacturing process is also more complicated, so the price of quality TR 90 eyeglasses frame is more expensive than others. It is very important that the they are fully dried to a moisture content of less than 0.1% during processing, otherwise the product will be brittle or unsightly, and the raw material loss will be large.

 

When processing high quality TR eyeglass frames, it is best to use a dehumidifier to remove moisture from the raw materials, so that the appearance and performance of the products are qualified. If there is no dehumidifier, it can only be produced when the weather is sunny and the air humidity is less than 50%. If the product produced in a dry environment is still unqualified, the injection temperature of the barrel needs to be increased to fully plasticize the raw materials.

 

As for the TR100 and TR120 frame optical glasses on the market, they are basically composed of the raw material PA12 of TR 90 frame optical glasses. The TR90 used by many domestic manufacturers is the raw material of the Swiss EMS company purchased. Due to the processing characteristics, the price of TR100 and TR120 frame optical glasses is not higher than that of TR 90 frame optical glasses.

(3) Impact resistance

 

The material for making high quality TR eyeglass frames is a memory polymer material with an anti-deformation index of 620kg/cm2, which is not easily deformed. Because TR eyeglass frames are impact-resistant, which can effectively prevent damage to the eyes caused by impact during exercise.

 

 

(4) High temperature resistance

 

High quality TR eyeglass frames can withstand 350 degrees of high temperature in a short time. TR eyeglass frames are not easy to melt, deform and discolor, which makes the service life of quality TR 90 eyeglasses frames longer.

 

Whether it is for people with poor eyesight or for people who are in pursuit of fashion, lightweight TR90 frame is a good choice. For the elderly, there are also TR reading glasses so that they can see things clearly.
