Half the weight of the frame, which is 85% of the nylon material, can reduce the burden on the nose bridge and ears, and is suitable for teenagers. The products made of TR material are wear-resistant, chemical-resistant, solvent-resistant, weather-resistant, non-flammable, and high-temperature resistant. TR90 is a memory polymer material with a slender deformation index of 620kg cm2, which is not easy to change the shape of the ruler.

Titanium is generally used in the production of high-grade frames, with strong corrosion resistance, high hardness, not easy to deform, ** not easy to be allergic to it, good texture, and relatively high price. TR90 has large elasticity, strong toughness, impact resistance, sports safety but difficult to color, generally painted on the outside, the price is relatively cheap, and it is more suitable for students to wear.

TR90 eyeglass frame is a fibrous material eyeglasses frame with memory ability, no chemical residue is released, in line with European regulations for food-grade raw materials, is the most fashionable lightweight eyeglass frame in the world. The TR90 frames are ultra-malleable.

Collision resistance, wear resistance, friction resistance and other characteristics, can reasonably avoid fitness exercise.

Damage to the eyes and face caused by cracking and abrasion of the eyeglass frame. Because of its specificity.

The molecular formula has good resistance in the natural environment at high temperatures.

It is not easy to deform, can withstand high temperature of 350 degrees in a short time, and is not easy to melt and ignite. And the surface layer of the TR90 eye frame is moistened, and the relative density is relative.

In the salt water, it will be suspended, which is lighter than other plastic glasses frames, about less than plates.

Half of the net weight of the frame is 85% of the polyester raw material, which can reduce the pressure on the nose bridge and the inside of the ear, which is suitable for teenagers and children.

Pure titanium frames.

It is the lightest of the glasses material, and you can know whether it is real or fake by almost weighing it by hand. There are also pure titanium glasses frames with very good hardness, not easy to deform, corrosion-resistant, and will not rust.

Spectacle frame plate frame, that is, plate glasses frame, the difference between plate glasses frame and TR90 is as follows:

First, the materials are different.

Plate glasses frames: The material of plate glasses frames is a high-tech plastic memory board, composed of acetate, propionate fiber, etc.

TR90: The material of TR90 is a kind of polymer material with memory.

Second, the process is different.

Plate glasses frame: The process of plate glasses frame includes material assembling process, engraving process, inlay process, etc.

TR90: The process of TR90 is mainly injection molding.

Third, the characteristics are different.

Plate glasses frame: Plate glasses frame has the characteristics of high hardness, good gloss, light and beautiful style.

TR90: TR90 has the characteristics of super toughness, crash resistance and wear resistance, and low friction coefficient.

Encyclopedia - TR90 glasses.

TR90 is a plastic titanium material, which is a polymer material with memory function.

TR90 is an ultra-light material for spectacle frames, and the coefficient of friction of the frame made from this material.

Low, tough, crash and wear-resistant, not only can it be worn for a longer time, but it is not easy to break glasses and cause injuries to the eyes and face during exercise.

Features of plastic titanium material:

This material is characterized by light weight, bright colors, impact resistance, high temperature resistance, etc., and is mainly used to make glasses frames, which is currently very popular in the world for ultra-light glasses frame materials.

Compared with nylon material, the weight of this material is only about 85% of that of nylon material, and its elasticity can reach twice that of nylon material. The color is bright and rich, and it lasts for a long time in an environment with a temperature of 350, and it is not easy to burn, melt or fade.

The glasses frame made of TR90 material has a low friction coefficient, strong toughness, and is resistant to collision and wear, and it is not easy to break the glasses and cause injuries to the eyes, face and other parts during the exercise. And this material will not release any residual chemicals, long-term contact with ** will not affect the human body of socks.

Nylon polymer material. TR90, also known as plastic titanium, is a kind of transparent nylon polymer with memory produced by the Swiss EMS company, which is called nylon 12 or PA12 by the chemical industry and material industry, which is a thermoplastic resin.

The material can withstand 350 high temperature without melting in a short time, and is a popular ultra-light frame material.

Features:

Lightweight, super toughness and elasticity, super ability to maintain shape, collision resistance, wear resistance, corrosion resistance, blue sky erosion, etc., are the biggest characteristics of TR90. TR90 itself is a colorless or colored transparent material, and the various colors or slag patterns commonly seen are a layer of decorative skin on the surface of the material through the spraying process.

Therefore, if the TR90 frame is used for a long time or is bent too many times, the surface of the frame will peel off, especially in low temperature environments.

tr90 good. Sunglasses block uncomfortable glare while protecting the eyes from UV rays. All of this is possible thanks to metal powder filters, which "select" light when it hits it.

Tinted glasses selectively absorb some of the wavelengths that make up the sun's rays because they use very fine metal powders (iron, copper, nickel, etc.).

In fact, when light hits the lens, it is reduced due to the so-called "destructive interference" process. That is, when certain wavelengths of light (in this case, ultraviolet A, ultraviolet B, and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, i.e., in the direction of the eye.

The overlapping of light waves is not accidental: the crest of a wave and the trough of the wave close to it are combined to cancel each other out. The phenomenon of destructive interference depends on the refractive index of the lens (i.e., the degree to which light deviates as it passes through different substances from the air) and also on the thickness of the lens.

Generally speaking, the thickness of the lens does not change much, while the refractive index of the lens varies according to the chemical composition. And the sunglasses can't be in direct contact with Taidan, shouting to let the sun shine directly.
