Below, we will explain the main uses of cellulose acetate flakes and cellulose acetate powder, and explain why they are supplied in different physical forms.

ONE、 Application of Cellulose Acetate Flake

This is the most common form of industrial supply, usually cellulose acetate, with a content of 54-56% Ac, easy to transport, stable to store, and used for reprocessing.

main purpose

1. Manufacturing acetate fiber bundles (TOW)

The most typical use is the production of acetate fiber bundles for cigarette filters (the world's largest application).

Slices can be easily added to the dissolution tank to make spinning solution.

2. Spinning and fiber production

Textile grade fiber (acetate fiber), used for clothing fabrics, ties, silk, etc.

Triacetate fibers are also mainly in the form of flakes.

3. Production of films, flakes, and substrates

Photo film, optical flake, display protective film, packaging film.

4. Plastic products (CA, CTA, CAB)

Dissolve it first to make plasticizers, and then press and stretch it into sheets or molds.

5. Coatings, inks, and adhesive substrates

CA sheet is used as a film-forming substance after dissolution, with good gloss and transparency.

Why use 'flake':

Suitable dissolution speed, stable transportation, and low moisture absorption are the standard forms for industrial dissolution processing.

TWO、 Application of Cellulose Acetate Powder

Powder is finely ground CA with a large surface area and fast dissolution, suitable for industries that require rapid mixing, uniform dispersion, or blending with other resins.

main purpose

1. High end coating materials

Nail polish, high transparent coating, optical coating.

The powder dissolves quickly and the system is uniform.

2. Ink and printing materials

Used as a film-forming agent and thickener; Suitable for gravure and flexographic printing inks.

3. Thermoplastic composite materials

CA powder can be mixed with biobased resins such as PLA and PBS to enhance flexibility and thermal stability.

4. Raw materials for water treatment membranes and gas separation membranes

Fine powder is used for uniform membrane preparation (reverse osmosis, nanofiltration, UF).

5. Pharmaceutical excipients (some grades)

As a controlled release film or coating material (but requiring pharmaceutical grade).

6. Liquid sheet and spraying process

Due to its fast dissolution, it is suitable for high-speed production lines.

Why use 'powder':

Dissolve quickly, easily mix with other solids or resins, suitable for processes that require uniform dispersion.
