Description

Cellulose Acetate is a versatile synthetic polymer derived from the acetylation of natural cellulose, offering an excellent balance of toughness, clarity, and processability. Its primary value lies in its ability to form durable, transparent films and fibers with good chemical resistance and low flammability. This makes it a critical material for manufacturers in the photographic film, textile, filtration, and consumer goods industries seeking sustainable, high-performance polymer solutions.

Application

• Film Production: As the base material for photographic film, LCD polarizer films, and protective coatings.
• Fiber & Textile Manufacturing: Used to produce acetate fibers for apparel linings, satins, and cigarette filters.
• Membrane Technology: Key component in the manufacture of ultrafiltration and reverse osmosis membranes for water purification.
• Plastics & Molded Goods: Employed in injection molding and extrusion for producing tool handles, eyewear frames, and consumer products.
• Coatings & Inks: Serves as a binder or additive to enhance the performance and drying characteristics of specialty coatings and printing inks.
• Pharmaceuticals: Used as an enteric coating material for tablets and capsules to control drug release.

Quality Control

Our Cellulose Acetate is manufactured under a stringent quality management system. Each batch is tested against critical parameters including acetyl content, viscosity, and moisture to ensure consistent performance for your application. Certificates of Analysis (COA) detailing purity, physical properties, and compliance with relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture.
