Description

Cellulose Pentaacetate is a fully acetylated derivative of cellulose, where all five hydroxyl groups per anhydroglucose unit are esterified with acetic acid. This chemical modification imparts high solubility in specific organic solvents and excellent film-forming properties, making it a valuable intermediate for advanced materials. It is primarily sought after by manufacturers in the coatings, plastics, and specialty chemical industries for producing high-performance films, membranes, and as a precursor for further chemical synthesis.

Application

• Film and Membrane Production: Used as a key raw material for manufacturing high-clarity, durable films and selective separation membranes.
• Advanced Coatings: Serves as a resin component in specialty coatings requiring excellent adhesion, chemical resistance, and gloss.
• Plastic and Resin Modification: Acts as a processing aid and modifier to enhance the properties of other polymers and composites.
• Chemical Synthesis Intermediate: Utilized as a precursor for synthesizing other cellulose esters and specialty organic compounds.
• Adhesive Formulations: Incorporated into high-performance adhesive systems where specific solubility and bonding characteristics are required.
• Laboratory and R&D: Employed in research settings for developing new polymeric materials and studying cellulose chemistry.

Quality Control

Our Cellulose Pentaacetate is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistency in acetyl content, viscosity, solubility, and purity. A comprehensive Certificate of Analysis (COA) detailing key parameters is provided with every shipment to support your quality assurance protocols.

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). Keep away from strong acids, bases, and excessive heat. The material is hygroscopic (moisture-sensitive) and should be handled in a low-humidity environment to prevent clumping or property changes.
