Plasticizer - an overview | ScienceDirect Topics
Plasticizers B.L. Wadey, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 VI.A.4.a Volatility Plasticizer loss causes plasticized PVC to shrink and become stiff. This can occur quickly at room temperature with low-molecular-weight plasticizers.
Pembuatan dan Karakterisasi Bioplastik Berbahan Dasar
The making of bioplastics is carried out for two variations of mixture, namely cassava starch as the material-based, glycerol + water as plasticizer, acetic acid (vinegar) as a catalyst and the...
Characterization of bioplastic based from cassava crisp home
The research result shows the highest value of tensile strength is 96.04 MPa, the highest elongation at break is 52.27%, and the value of water-resistant test is 22.68%. Morphology analysis by using SEM shows uneven surface and there is fracture in its cross-section.
Influence of Weather and Purity of Plasticizer on Degradation
It was established that highly pure glycerol takes a shorter period of degradation as seen in the reduced degradation time of the bioplastics made with commercial grade glycerol. This suggests that the purity of glycerol and the hydrolyzing agents directly impact on the rate of degradation of bioplastic. 4. Discussion
- Does plasticizer type affect the equilibrium moisture content of films?
- Plasticizer type did not significantly affect the equilibrium moisture content of films. Sucrose added films were the most fragile at low RH, while GLY films were the most hygroscopic. However, at RH of 76–90%, sucrose films showed similar resistance compared to other plasticized films.
- What is the final residue of PM plasticizers during TGA?
- The final residue of the PM plasticizers during TGA is about 51.48%, showing the existence of silica that accomplish desired mechanical and thermal properties. Although, the PM plasticizers have good CI and CS values of 6.5% and 460.3 nm, respectively.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Which citrate esters are used as plasticizers in ca?
- Other citrate esters reported as plasticizers in CA are tributyl citrate (TBC) and acetyl tributyl citrate (ATBC) , . When ATBC was used in CA, white and opaque films were obtained by casting. Further DSC analysis demonstrated the presence of a crystalline peak.
- Can acylating reagents be used for internal plasticization of ca?
- In this regard, effective internal plasticization of CA can be obtained with acylating reagents consisting of a terminal bulky moiety spaced from CA chains by a linear chain: they have been found to efficiently separate macromolecular chains without generating detrimental stiffening interactions , .
- Is liquefied wood flour a good plasticizer for polylactide?
- RESULTS: Liquefied wood flour and rice bran derived esters were synthesized and evaluated as novel green plasticizers for polylactide (PLA). The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing.
