Tr90 Frame Eyeglasses is your good choice

With the development of the glasses industry, the application of new materials in the manufacture of glasses frames emerges in an endless stream. While the frame uses a new material design to highlight its "lightness", its "practicability" must not be ignored. Tr90 Frame Eyeglasses satisfies the three elements of "lightweight, durable and stylish" at the same time, and is welcomed by the market.

• Glasses of non-metallic materials

• Spectacle frames in different materials

Glasses of non-metallic materials

1. Cellulose acetate

Cellulose acetate material has been the main material for the production of non-metal mirror frames since the 1980s. Cellulose acetate has two processes: injection molding and sheet forming, represented by sheet mirror frames. It is deeply loved by customers and is the enduring mainstream product of non-metallic materials for spectacle frames.

Advantages: non-fading, non-allergic, easy to process, clear product streamlines, and a strong sense of three-dimensional, fashion, etc.

Disadvantages: poor frame stability, easy to deform.

2. Tr90 Frame Eyeglasses

This material is a composite superelastic resin material first invented by Koreans and applied to the manufacture of glasses.

Advantages: Tr90 Frame Eyeglasses are light in weight and slightly lighter than pure titanium; they have excellent flexibility, are not easy to deform, and have good elastic strength.

3. Tungsten titanium

Tungsten titanium: also known as plastic steel, tungsten carbon, tungsten carbon plastic steel, aviation PEI material.

Advantages: light, soft, high hardness equivalent.

Disadvantages: The pile head of the mirror leg is easy to break, the hinge is easy to break, the material is "ultra-brittle" the shear resistance is extremely poor, and the nose pad bracket and stipe are easy to fall off. Tungsten-titanium frames are easily damaged, so children's frames cannot be made.

4. PA66

PA66 is also known as nylon 66, nylon 66 short fiber, and polyhexamethylene adipamide, nylon 66 has a higher melting point in polyamide materials, and is a semi-crystalline material.

Advantages: high tensile strength, excellent flexibility, impact resistance wear resistance, good low-temperature characteristics, self-extinguishing.

Disadvantages: Due to the unreasonable design of the spectacle frame made of PA66 material, in addition to being "light", it cannot show the advantages of "high tensile strength" and "flexibility and impact resistance", "not plastic", "pile head and hinge The disadvantages such as "easy to break at the joint" are more obvious.

Spectacle frames in different materials

At present, metal materials commonly used in spectacle frames are: pure titanium, titanium alloy, β titanium, and memory titanium alloy (titanium-nickel alloy); commonly used non-metallic materials are: cellulose acetate, Tr90 Frame Eyeglasses, tungsten titanium (composite material), PA66, etc. Understanding the advantages and disadvantages of various materials will help manufacturers choose the best solution when designing and producing spectacle frames.
