Biodegradation was measured in an in vitro aerobic culture system that was designed to capture 14 CO 2 produced by the aerobic microbial metabolism of the cellulose esters. Product description.
If your main criterion for a frame is lightness, then definitely consider propionate frames. Radiolabeled cellulose esters were synthesized with either [1‐ 14 C]‐acetate or [1‐ 14 C]‐propionate and back hydrolyzed to the desired degree of substitution (DS) ranging from 1.77 to 2.64. No. Eastman Cellulose Acetate Propionate CAP-482-0.5 is a low-odor, free-flowing powder.
PubChem Substance ID 24860961.

9004-39-1) resulting in up to 49 weight-percent propionate esters. Cellulose acetate (CAS Reg. Other esters (e.g., cellulose formate, cellulose propionate, cellulose butyrate) may be formed, but they do not have the widespread commercial applications of cellulose acetate. It's lightweight and has more transparency and gloss than other plastics. The resulting films have fast solvent release, excellent antiblocking properties and grease resistance. View information & documentation regarding Cellulose acetate propionate, including CAS, MSDS & more. CAB and CAP are tougher than CA but all are chemically resistant, electrically insulating and sound absorbing. 9004-35-7), and optionally modified with propionate to form cellulose acetate propanoate (CAS Reg.
