High-end sunglasses brands such as Celine and Gucci widely use acetate sheets to showcase their unique luster and delicate craftsmanship. COPPER FOLKS uses high-end sunglasses materials to create affordable sunglasses that are both functional and aesthetic.

When choosing an ideal pair of sunglasses, the appearance design is certainly important, but the choice of material is the key to affecting comfort, durability and overall texture. Copper Folks always insists that only by understanding the materials can we find glasses that truly fit our life and taste. In this article, we will introduce in detail the three most common frame materials on the market - PC plastic, TR90 resin, and acetate fiber, and help you understand the meaning behind each material.

PC plastic (Polycarbonate)｜Balance between lightness and durability

PC plastic is popular for its excellent impact resistance and light weight. This material has excellent pressure resistance and can effectively reduce the risk of damage even if it encounters collisions or falls during daily use. The PC frame feels light and is suitable for long-term wear. However, compared to other high-end materials, PC is slightly thinner in terms of detail and texture, and its appearance is mostly simpler in design.

For the everyday user : Need a pair of sunglasses that are lightweight, durable, and reasonably priced.

TR90 resin | High elasticity, born for dynamic life

TR90 is a nylon material with high toughness and excellent elasticity. It has stronger resistance to twisting and can return to its original shape even after a large bend, making it suitable for wearing when frequent activities or exercise are required. The TR90 material is both lightweight and durable, providing a comfortable experience that fits the face shape and is not prone to causing a sense of oppression due to long-term wear.

For active users : those who seek flexibility and comfort, and value durability.

Acetate｜Natural texture, detail-oriented choice

Acetate, commonly known as "acetate", is a high-end eyewear material made from natural cotton fibers.
It has a unique luster and layering, a warm texture and a smooth touch. Each pair of sheet metal frames undergoes multiple grinding and polishing processes during the production process, so the color is naturally rich, the texture is delicate and unique.

More importantly, many of the world's top fashion brands, such as Celine, Gucci, Dior, Prada, etc., use acetate as their main material , not only because of its excellent physical properties, but also because of the high-quality texture and craftsmanship it exhibits.

Acetate frames have good durability and plasticity. After long-term wearing, the frames can adjust slightly with body temperature, fit the facial curve better, and bring personalized comfort.

Suitable for users who pursue quality and personal taste : they care about details, attach importance to wearing experience, and hope that glasses can become an extension of their personal style.
