What is excellent cellulose acetate granules ?
Cellulose acetate (CA) granules are thermoplastic cellulose ester polymer granular raw materials prepared by the acetylation chemical modification of natural cellulose as the core feedstock, referred to as CA granules for short. They are among the most mature types with the optimal processability in industrial applications among cellulose derivatives, presenting a regular particle form in white or translucent appearance, and can be directly used in plastic molding processes such as extrusion, injection molding and blow molding.
It can be classified into multiple variants ,such as CA Granules,Cellulose Acetate Plastic Granules,CA Resin Granules,Cellulose Diacetate Granules (CDA),Cellulose Triacetate Granules (CTA),Biobased Plastic Granules,Spinning-grade CA granules,Injection-grade CA granules,Cigarette-grade CA granules,Medical-grade CA granules,High-transparency CA granules and so on. We have been producing excellent cellulose acetate granules since the year 2003.
