Product Description
Cellulose Acetate Butyrate (CAB)
Cellulose Acetate Butyrate (CAB) is used to manufacture plastic sheets and films known for their high transparency and excellent weather resistance. It also serves as a leveling agent and film-forming substance in various paints. Increasing the butyryl group content reduces its density and broadens its solubility range. Contains 12%-15% acetyl and 26%-29% butyryl.
This material is available as transparent or opaque granules, characterized by their toughness, good weathering, and cold resistance.
