Standard Classification System and Basis for Specification for Cellulose Acetate Butyrate Molding and Extrusion Compounds (CAB)
2015

ASTM Vol.08.01 (2022)
This classification system covers requirements for plasticized cellulose acetate butyrate thermoplastic compounds suitable for injection molding and extrusion. These compounds have a butyryl content less than 38 % and an acetyl content less than 15 % and can contain dyes and pigments. This classification system does not include special materials compounded for special applications. Cellulosic plastic materials, being thermoplastic, are reprocessable and recyclable. This classification system allows for the use of those cellulosic materials, provided that all specific requirements of this classification system are met. The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are specified by using the suffixes as given in Section 5.
