Standard Test Methods of Testing Cellulose Acetate Propionate and Cellulose Acetate Butyrate

Importancia y uso:

7.1 Ash content gives an estimate of the inorganic content of cellulose ester samples. The presence of high levels of inorganic content (ash) can be detrimental to the melt stability and optical clarity of a cellulose ester in melt processing or act as a potential source of insolubles when the ester is used in solution.
