Study on Cellulose Acetate Butyrate/Plasticizer Systems by
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 Blends - Effect of Plasticizers on Properties and
Some of the natural and biodegradable plasticizers that have been considered for the plasticization of cellulose derivatives include triethyl citrate, triacetin, diacetin, epoxidized soybean...
Thermo-mechanical properties and blend behaviour of cellulose acetate
This work brings together thermo-mechanical and structural information for plasticized cellulose acetate (CA) by lactates and octanoic acid. CA are processed with plasticizer due to their...
The Effect of Concentration and Type of Plasticizer on the Mechanical
on the Mechanical Properties of Cellulose Acetate Butyrate Organic-Inorganic Hybrids 143 be used as lower cost, partial replacement for a primary plasticizer. It is possible that a plasticizer used in one formulation as a primary plasticizer could be used in a second formulation as a second one [10, 11].
- What is plasticized cellulose acetate (CA)?
- Plasticized cellulose acetate (CA) is one of the most applied bio-based polymers due to its structural properties and easy processing. Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application.
- Can acylating reagent be used to plasticize cellulose acetate?
- Overall, an acylating reagent consisting of a linear spacer segment attached to the cellulose chain with a terminal bulky aromatic group is the optimal structure for the internal plasticization of cellulose or cellulose acetate. Thermoplastic cellulose esters would resolve migration problems related to CA plasticized with external plasticizers.
- Can cellulose acetate be plasticized?
- Many studies have been carried out for characterizing the miscibility, the plasticization and the mechanical properties of commercial cellulose acetate with a DS of 2.45 (CDA) and its plasticized samples prepared via solvent casting method (Bao, Long, & Vergelati, 2015).
- Is plasticized acetate a biodegradable material?
- In practice, most applications use cellulose acetate with DS 2.2–2.4, which is less prone to water absorption and, consequently, to biodegradation at ambient conditions. For these reasons, plasticized acetate, still used in niche sectors such as eyewear and jewelry, cannot be considered a biodegradable material. 6. Conclusions 6.1.
- Do plasticizers migrate out of cellulose acetate?
- Moreover, plasticizers that migrate out of the material could harm human health and contaminate the environment , . In this regard, understanding the mechanisms of CA plasticization is crucial to find room for improvement in tailoring cellulose acetate properties with a well-designed plasticizer molecule.
- Which polar plasticizer is suitable for cellulose acetate?
- A polar plasticizer with a proton-acceptor character, such as an ester, is useful in polymers with average polarities , e.g., cellulose acetate. Apart from the chemistry of the selected plasticizer, other factors influence compatibility.
