Cellulose acetate butyrate
(CAB; butyryl content 35-39%) was purchased from Acros Chemical (Pittsburg, PA).
Grades of cellulose acetate butyrate
, for example, can vary by the ratio of acetic to butyric ester groups, hydroxyl number, and molecular weight.
1), such as cellulose acetate (CA), cellulose acetate propionate (CAP), and cellulose acetate butyrate
(CAB), are thermoplastic materials produced through the esterification of cellulose.
One of Mexico's most cherished national monuments, El Angel de la Independencia, an enduring symbol of Mexican unity and freedom since its construction in Mexico City in 1910, recently underwent restoration work that included the use of uniquely formulated cellulose acetate butyrate
(CAB)-based coatings additives created by Eastman.
Eastman Chemical Company has published a new technical tip that is designed to make the formulation of waterborne coatings with carboxymethyl cellulose acetate butyrate
(CMCAB) cellulose esters easier.
