Study on Cellulose Acetate Butyrate/Plasticizer Systems by
Abstract Cellulose acetate butyrate (CAB) is a widely used binder in polymer bonded explosives (PBXs). However, the mechanical properties of PBXs bonded with CAB are usually very poor, which makes the charge edges prone to crack.

Cellulose acetate butyrate (CAB), with the molecular formula of [C 6 H 7 O 2 - (OCOCH 3) X - (OCOC 3 H 7) Y - (OH) 3-X-Y] n, is the most commonly used binder in polymer bonded explosives (PBXs). In the structure of cellulose ester, hydroxyl groups are co-esterified with acetic acid and butyric acid [ 1 ].

- What is cellulose acetate butyrate (CAB)?
- Cellulose acetate butyrate (CAB), with the molecular formula of [C 6 H 7 O 2 - (OCOCH 3) X - (OCOC 3 H 7) Y - (OH) 3-X-Y] n, is the most commonly used binder in polymer bonded explosives (PBXs). In the structure of cellulose ester, hydroxyl groups are co-esterified with acetic acid and butyric acid .
- What are the mechanical properties of cab/plasticizer systems?
- The shear moduli (G) of optimal CAB/plasticizer systems are similar, but their bulk moduli (K), Poisson’s ratios (μ), K/G ratios and Young’s moduli (E) are all in the order of CAB/Bu-NENA >CAB/A3 >CAB/GAPA, suggesting the mechanical properties of CAB/Bu-NENA are the best.
- What are the tensile strengths of cab/plasticizer systems?
- The tensile strengths (σ) and Young’s moduli (E) of CAB/plasticizer systems are in the order of CAB/A3>CAB/Bu-NENA>CAB/GAPA, indicating that the mechanical strength and resistance capacity to deformation of CAB/A3 are best, significantly better than CAB/Bu-NENA and CAB/GAPA.
