Cellulose Acetate (abbreviated as CA)

Cellulose Acetate (abbreviated as CA) is a semi-synthetic polymer material made from natural cellulose. It combines the texture of natural materials with the practicality of synthetic materials, and is commonly used as raw material in fields such as eyewear frames, accessories, and textiles. 
Core Feature 
- Excellent texture: The surface has a soft luster and a gentle touch, similar to natural materials such as horn and tortoiseshell. It offers high comfort during wearing and usage.
- Good processability: It softens and shapes easily after heating, can precisely present complex frame curvatures and patterns, and is not prone to cracking during cutting and polishing, making it suitable for fine processing.
- Strong stability: Resistant to sweat stains and weak acids and alkalis, it does not deform or fade due to sweat erosion, and maintains good appearance over a long period of use.
- Light weight: Its density is lower than that of most resins and metals. The glasses frames made from it have a low weight sensation when worn, reducing pressure on the nose bridge and ears.
- Environmentally friendly and recyclable: Made from natural cellulose (such as wood pulp and cotton short fiber), it can naturally degrade or be recycled after disposal, being friendly to the environment. 
Main application fields 
- Eyewear industry: It is the mainstream raw material for mid-to-high-end plastic eyeglass frames, capable of manufacturing frame rings and temple parts. It can achieve rich colors through dyeing, and is comfortable to wear and less likely to cause allergies.
- Textile industry: The produced acetate fiber fabric (commonly known as "acetate silk") has a silk-like luster and drape, and is often used in high-end clothing, scarves, ties, etc.
- Accessories and daily necessities: It is used for making hair clips, brooches, buttons and other accessories, as well as pen stems, makeup brush handles, etc., combining beauty and durability.
