Acetate and acetate combined with steel.
Also known as carbon crystal frames, they are manufactured using cold working techniques, resulting in fine, high-quality, and durable frames. Most brand-name acetate eyeglass frames are made from this material. They offer diverse styles and vibrant colors, making them a favorite among mid-to-high-end fashion brands. Their characteristics include high strength, sturdiness, shape memory, and resistance to deformation. Acetate frames can be distinguished from injection-molded frames by the visible cutting marks on the temples. Among the world's best acetate frames, those from Italy are considered the highest quality, followed by those from Japan. Acetate is a type of plastic, a synthetic polymer compound, also known as macromolecules or polymers, commonly referred to as plastics or resins. It can be freely shaped. The main component of plastics is resin. Plastics are actually a type of synthetic resin, similar in shape to natural resins like pine resin, but are called plastics because they are artificially synthesized through chemical means. Based on their different physical and chemical properties, plastics can be divided into two main categories: thermoplastics and thermosetting plastics (resins). The plastics (resins) commonly used to manufacture eyeglass frames are mainly thermosetting plastics such as cellulose acetate, epoxy resin, and celluloid.
Performance: Lightweight, high hardness, good gloss, and the combination with steel enhances its strength. It is also aesthetically pleasing, resistant to deformation and discoloration, and durable. It has a certain degree of elasticity; when slightly bent or stretched and then released, the shape memory acetate will return to its original shape. Frames are made from cellulose acetate sheets. Acetate is lightweight, and the combination with steel enhances its strength and aesthetics. It is not easily flammable, almost unaffected by ultraviolet radiation, has high hardness and good gloss, is not easily heat-processed, has a beautiful design, and is not easily deformed after wearing.
Advantages: Acetate frames exude fashion, are easier to match with clothing, and combine the weight of acetate with the texture of metal, reflecting individuality and style. The frame shape combines modern and classic features, with streamlined shapes and richly colored borders, achieving a perfect seamless integration.
