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 Thermoplastics with High Modulus
The CDA- g -PLA copolymers with the DP PLA of 3–9 can be directly processed to transparent plastics by melt processing without any external plasticizers, because of their low Tf s of 170–215 °C. More impressively, the CDA- g -PLA can act as the macromolecular plasticizer.
Improvement of the functional properties of cellulose acetate
Cellulose acetate (CA) was used for the preparation of food packaging film. Glycerol and n-propanol were introduced, as plasticizer and transparent agent, respectively for evaluating the possible changes of the film functional properties on tensile strength and transparency. The transmittance, haze value, tensile strength and flexibility were acquired by using optical and mechanical analyses
Natural-based plasticizers and biopolymer films: A review
Attributes and performance of plasticizers. Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) [12], [13]. The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary
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. In the current study, seven plasticizers, including bis (2,2-dinitro propyl) fo
- Can cellulose acetate be used as a plasticizer?
- Due to their high glass transition temperature, cellulose acetate-based systems are processed when blended with plasticizers. It is thus of utmost importance to study the miscibility and plasticizing effects of various molecules. We prepared CDA films via solvent casting method with diethyl phthalate as the plasticizer.
- What is plasticized cellulose acetate polymer?
- Plasticized cellulose acetate polymers have been processed by injection molding. A high impact resistance (40 kJ/m²) at room temperature requires plasticizer content larger than 25%. The brittle-to-ductile transition is broadened over more than 60 °C with increasing the plasticizer content.
- Which plasticizer is incorporated in cellulose acetate films?
- The common plasticizer incorporated in cellulose acetate films is glycerol . This plasticizer has been shown to improve the mechanical and thermal properties of cellulose acetate films.
- How strong is plasticized cellulose acetate?
- Plasticized cellulose acetate exhibit a brittle-to-ductile transition from a low impact strength to a high impact strength of order 40 kJ/m². Obtaining a high impact resistance at room temperature requires plasticizer content larger than 25 wt.%. An important strain hardening is obtained for samples with both plasticizers during tensile experiment.
- Can cellulose acetate films be plasticized with glycerol and tehp?
- According to these results the cellulose acetate films without any plasticizer and the films plasticized with glycerol and TEHP showed a very low degradation rate after 60 days. While the degradation rate is significant for cellulose acetate films plasticized with rosemary essential oil.
- Are plasticized cellulose acetate systems dielectric?
- Most of these dielectric studies, however, have been focused on cellulose and its derivatives, and only few results have been reported about dielectric properties of plasticized cellulose acetate systems. Seymour et al., 1979 focused on phthalate plasticizers such as dioctyl phthalate and diphenyl phthalate.
