Acetate spectacle frames are the most common spectacle frames on the market. It has a light texture and good gloss, which is very popular among young men and women. Many famous brand glasses are made of acetate. So, what about acetate spectacle frames?

Cellulose Acetate

Acetate is a kind of thermoplastic resin obtained by esterifying acetic acid to acetic anhydride under the action of a catalyst. Acetate is resistant to water, gasoline, mineral oil, and lipids, weak alkaline solutions, and acids, excellent weather resistance, not resistant to ethanol, strong acids, and strong alkaline solutions. During thermoforming, it is very necessary to dry the material before forming. Acetate was born in the early 20th century, and was successfully trial-produced and industrialized by the UK in the early 1920s. At present, it is the second-largest variety in cellulose fiber after viscose fiber. Acetate can be used to make textiles, cigarette filters, film bases, and plastic products.(https://www.koalaeye.com/collections/acetate-eyeglasses)

Plate Frame

Glasses processed with acetate sheets become sheet frames. The plate frame is not easy to burn, the specific gravity is small, and the base arc is not irradiated by ultraviolet rays to change color. In addition, it has high hardness, good gloss, and durability, but it is not easy to bake and the temperature is 115-130 degrees. The style is more beautiful, and it is not easy to deform after wearing. The current market is that the plate frame combines the thickness of the plate and the metal texture, and combines different types of lenses to create fashion and personality. There are not only retro-style frames, but also popular frames, combining a variety of elements to create classic glasses frames. Its workmanship has undergone complex processes such as turning, grinding, and polishing, so it is relatively high-end.

Injection frame

Acetate cellulose pellets are extruded by an injection molding machine, which is called an injection frame. Its characteristic is that it saves raw materials, can be mass-produced, has a lower cost, and is cheaper than a plate rack. But the firmness is not as good as the plate frame. However, injection frames are mostly used for glasses for the elderly and children because of their lightweight and resistance to allergies. The injection frame is made of laminated plastic. It is made by pasting a thin layer of plastic of one color on another thicker layer of plastic. Thick materials are mostly transparent pigments. It is also made of three or more layers of plastic.
