Description

Benzoylated Cellulose is a chemically modified cellulose derivative where hydroxyl groups are esterified with benzoyl chloride. This modification imparts enhanced solubility in organic solvents and improved thermoplastic properties compared to native cellulose, making it a valuable functional polymer. It is primarily utilized in advanced material science and specialty chemical applications where tailored polymer characteristics are required. Industries such as coatings, controlled-release systems, and specialty films benefit from its unique chemical profile.

Application

• As a film-forming agent and modifier in specialty coatings and lacquers.
• In the formulation of controlled-release matrices for agricultural or pharmaceutical actives.
• As a processing aid and compatibilizer in polymer blends and composites.
• For the manufacture of specialty membranes and filtration materials.
• In adhesive formulations requiring specific solubility and rheological properties.
• As a benchmark material for research in polymer chemistry and material science.
• Potential use in encapsulation and microencapsulation technologies.

Quality Control

Our Benzoylated Cellulose is produced under a rigorous quality management system. Each batch is tested to ensure consistent properties such as degree of substitution, viscosity, and purity. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment. We adhere to relevant industry standards and can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
