Cellulose Acetate Butyrate from Mexico
Cellulose acetate butyrate combines acetate and butyrate esters on cellulose, used in specialty plastics and coatings. While typically Chapter 39, high-purity monomeric analogs classify under HTS 2940.00.60.00 as chemically pure sugar esters. Provides mixed ester functionality for thermoplastic applications.
