Anotácia

This specification 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 may or may not contain dyes and pigments. This specification does not include special materials compounded for special applications. Cellulosic plastic materials, being thermoplastic, are reprocessable and recyclable. This specification allows for the use of those cellulosic materials, provided that all specific requirements of this specification are met. Test specimens of the thermoplastic compounds shall conform to the prescribed specific gravity, tensile stress at yield, flexural modulus, Izod impact strength, water absorption and weight loss on heating. The materials shall also be subject to color-visual, color-quantitative, and plasticizer content analysis.
