Description

Cellulose Carbonate is a chemically modified cellulose derivative where carbonate groups are introduced onto the cellulose backbone, creating a unique polymer with tailored properties. This compound is valued for its ability to enhance material performance in advanced applications, offering improved solubility, film-forming characteristics, and reactivity compared to native cellulose. It serves as a critical functional material for industries focused on specialty coatings, controlled-release systems, and high-performance composites, where precise chemical modification is required.

Application

• Pharmaceutical Excipients: Used as a functional polymer in controlled-release drug delivery matrices and tablet coatings.
• Specialty Coatings & Films: Acts as a base material for creating biodegradable, high-barrier films and protective coatings.
• Advanced Composites: Serves as a reactive intermediate or reinforcing agent in the formulation of bio-based composite materials.
• Chemical Synthesis: Utilized as a starting material or protecting group intermediate in organic and polymer synthesis.
• Laboratory Research: Employed in R&D for studying cellulose chemistry and developing new biomaterials.
• Cosmetic Formulations: Functions as a texture modifier or film-forming agent in advanced personal care products.

Quality Control

Our Cellulose Carbonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as degree of substitution, assay, and impurity profiles. We support compliance with relevant industry standards and can tailor specifications to meet specific customer requirements.

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 sealed to prevent absorption of atmospheric moisture, which can affect product performance.
