Description

Cellulose Acetate Butyrate (CAB) is a high-performance thermoplastic derived from the esterification of cellulose with acetic and butyric anhydrides. This versatile material is prized for its excellent combination of durability, clarity, and weatherability, making it a superior choice for demanding applications. Key industries that rely on CAB include coatings, plastics, and specialty films, where its unique properties solve critical formulation challenges.

Application

• High-Performance Coatings: Used in automotive, wood, and metal coatings for superior flow, gloss, and resistance to UV degradation and moisture.
• Plastic and Resin Modification: Acts as a key component in thermoplastic formulations to enhance toughness, clarity, and dimensional stability.
• Printing Inks and Lacquers: Provides excellent adhesion, fast drying times, and high gloss in specialty ink and lacquer systems.
• Adhesives and Sealants: Imparts flexibility, strength, and environmental resistance to adhesive formulations.
• Specialty Films and Membranes: Utilized in the production of films requiring high transparency, toughness, and gas barrier properties.
• Consumer Goods and Tool Handles: Found in durable, glossy finishes for tools, eyewear frames, and other molded goods.

Quality Control

Our Cellulose Acetate Butyrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as butyryl/acetyl content, viscosity, and hydroxyl value. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee product integrity and traceability for our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
