What is the material of the frame? What is the material of the frame?

1, carbon fiber. Carbon fiber is also called carbon fiber (CF). Carbon fiber is a new generation of reinforced fiber, which is soft outside and rigid inside, and has the reputation of "black gold". Its weight is lighter than aluminum, but its strength is higher than steel. But also has the characteristics of corrosion resistance, high modulus and skin friendliness, and is an important material for national defense, military industry and civil use. Rock-solid and tough as hair, it has satisfied people's tireless pursuit of quality in the field of materials since ancient times. Compared with other glass materials, carbon fiber materials have the advantages of ultra-light, super strength, wear resistance, corrosion resistance, high modulus, environmental protection and skin-friendliness, so they are also widely used in aerospace, national defense, automobile industry, energy equipment, construction engineering and other fields.

2. plates. Flat plate is one of the most common glass materials on the market. It is light in weight, excellent in stability and firmness, and the wearer does not need to worry about the damage of the glasses frame. Plate is a fashionable, popular and classic glasses material. Its varied colors and styles not only satisfy the wearer's pursuit of color, but also give buyers enough choice space to make you shine on different occasions. At the same time, it also has the advantages of delicacy, good quality, durability, diverse colors, strong texture, easy processing and no deformation at room temperature, and is deeply loved by people.

3. titanium. Titanium is also one of the most common glasses materials on the market. It is light, light and comfortable, and its material is the lightest among glasses. Moreover, its hardness is very good, the spectacle frame is not easy to deform, corrosion-resistant, rustless and will not cause skin allergy, so it is more durable. However, it also has defects, the disadvantage is that the material is soft, and the border with too thin lines may have poor stability and strength. Generally speaking, pure titanium spectacle frames are more suitable for slightly mature people to wear, highlighting the sense of texture and professionalism. Young or middle-aged people who work choose it more.

4. metal. There are many kinds of metals. At present, there are three kinds of metals on the market: copper alloy, nickel alloy and precious metal. These three materials have certain advantages such as hardness, softness, elasticity, corrosion resistance and bright colors, so the glasses made are very durable.

5、TR90。 TR90 is a kind of polymer material with memory function and the most advanced and popular ultra-light frame material in the world. It has super high temperature resistance, and can survive in the environment above 380 degrees without deformation.

6. Memory plastic. This is a kind of glasses frame made of nonmetallic material, which has good elasticity and light weight. Glasses frames made of different plates can be twisted at will, and even if they are deformed by unexpected external impact, they can automatically return to their original state.

7. Natural materials. Natural materials used to make spectacle frames include special wood, animal horns and tortoise shell materials. Generally, wooden frames and horn frames are rare, and tortoise shell frames are the most representative. Tortoise shell material is a spectacle frame made of tortoiseshell produced in tropical ocean. Its characteristics are light weight, good gloss, durability and preservation value. It is a top-grade product of its kind, and it is very popular with male wearers over middle age. Its disadvantage is that it is easy to break, but it can be repaired by bonding after breaking.

8. Non-metallic. Generally, nonmetals used to make glass are mainly made of synthetic resin, which can be roughly divided into thermoplastic resin and thermosetting resin. Common resin materials are acetate fiber, propionic acid fiber, epoxy resin, carbon, nylon and so on. Most children's sunglasses are made of this nylon material, because the nylon frame with higher elasticity can better fit the skin, improve comfort and ensure safety.
