Description

Cellulose Propionate is a thermoplastic cellulose ester derived from the reaction of cellulose with propionic acid. This material is valued for its excellent toughness, clarity, and dimensional stability, making it a high-performance alternative to other cellulose esters and standard plastics. It is primarily utilized in industries requiring durable, transparent, and easily moldable materials. Cellulose Propionate CAS NO 9004-48-2 offers a unique balance of properties suitable for demanding technical and consumer applications.

Application

• Injection Molding and Extrusion: Used for producing high-clarity, impact-resistant components such as tool handles, eyewear frames, and appliance parts.
• Film and Sheet Production: Manufacture of transparent, tough films for packaging, decorative laminates, and protective coverings.
• Coatings and Inks: Serves as a film-forming agent and binder in specialty coatings, lacquers, and printing inks, offering good adhesion and gloss.
• Adhesives and Sealants: Acts as a modifier to enhance flexibility, tack, and bonding strength in various adhesive formulations.
• Controlled-Release Matrices: Employed in pharmaceutical and agrochemical applications for encapsulation and sustained-release systems.
• Specialty Fibers: Used in the production of high-tenacity fibers for technical textiles and filtration media.

Quality Control

Our Cellulose Propionate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent properties such as propionyl content, viscosity, and thermal stability, meeting the requirements for its intended industrial applications. Certificates of Analysis (COA) detailing key specifications are available upon request 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent moisture absorption, which can affect processing and final product properties.
