Product Description
Cellulose acetate is a thermoplastic resin obtained by esterification with acetic acid as solvent and acetic anhydride as acetylating agent under the action of catalyst. As a porous membrane material, it has the characteristics of high selectivity, large water permeability and simple processing.
Cellulose acetate can be used for many purposes. Generally speaking, it can be used to make enteric coating of drugs, cellulose acetate filter membrane, etc. It can also be used to prepare solvent-based adhesive and bond plastic products such as glasses and toys.
Different kinds of cellulose acetate are more widely used after selecting different additives. Such as cigarette filter tip, plastic film, handlebar, handle, pen holder, audio tape, film, X-ray negative, etc. are all from cellulose acetate, and even used for hemodialysis, hemofiltration membrane and artificial kidney membrane materials.

CA is a very easily available man-made fiber with low cost and good weaving performance. Its properties make it a beautiful fiber. CA is used in satin, brocade, taffeta and other fabrics to improve their luster, body, drape and beauty.
1. Touch: soft, smooth, dry, comfortable and elastic;
2. Comfort: good permeability, core material, fast drying, no static adsorption;
3. Non-toxic, harmless and non-allergic to long-term skin contact.
4. Fibrous and plastic;
5. Selective adsorption and removal of some low-content organic substances;
6. It is easy to use plasticizer, heat, or pressure to make them stick together;
7. It is soluble in many common solvents (especially acetone and other organic solvents), and can be soluble in other kinds of solvents after modification, such as water;
8. Hydrophilicity: CA is easy to wet, has good liquid permeability and excellent adsorption; In the fabric, it is comfortable and sweat-absorbing, but when CA is wet, the strength decreases;
9. Large specific surface area;
10. It can be prepared from new raw materials: wood pulp;
11. It can be used as mixed fertilizer or burned;
12. It can be colored, but since CA is not suitable for cotton and rayon, special dyes and pigments are required;
13. Mildew resistance;
14. It is easy to deteriorate in alkaline solution and strong oxidant;
15. It can be dry cleaned or washed with water, and usually does not shrink.
Purpose
It is used for making enteric coating, acetate fiber filter membrane, etc. for making acetate fiber plastic, cellulose acetate filter membrane, etc.
Cellulose acetate can be divided into diacetate spinning grade cellulose acetate, diacetate plastic grade cellulose acetate and cellulose triacetate according to different products.
1. Diacetate spinning grade cellulose acetate: spinning grade products are internationally recognized non-toxic and harmless products that have not yet found alternative materials. Its most important and main use is as filter equipment, especially cigarette filter tip, which is used in a very large amount. In addition, it is used as medical filter equipment, such as blood filter equipment; At the same time, it can also be used for spinning, with the luster of silk, as the name of high-grade suits.
2. Diacetate plastic grade cellulose acetate: mainly used for making plates and sheets. The main products include glasses frame, advanced tool handle, etc.
3. Cellulose triacetate: mainly used as electronic film, such as polarizer of liquid crystal display, cinematographic film and camera film.
