Long- and short-term stability of plasticized poly(lactic
Addition of plasticizers (regardless of plasticizer type) to the PLA, even at lower loading levels (5 wt%), decreased the yield strength and modulus of PLA. It is known that plasticizers result in a decrease in the intermolecular forces between the polymer chains, which lowers the polymer chain cohesion . Yield strength and the modulus of PLA
High molecular weight plasticizers in thermoplastic starch
The effect of higher molecular weight plasticizers on the morphology development and mechanical properties of compatibilized 20 TPS/80 PE blends has been investigated. All the plasticizers were chosen from the polyol family namely glycerol, sorbitol, diglycerol and polyglycerol.
Influence of plasticizer (triphenyl phosphate) loading on
Triphenyl phosphate is used as a plasticizer in order to minimize the residual solvent and its effect on surface morphology of the prepared coatings. The residual solvent has decreased with an increase in triphenyl phosphate loading in various coatings having 5% poly (styrene) with 0–2% triphenyl phosphate.
Simultaneous recovery of high-purity copper and polyvinyl
The effects of each solvent type on the plasticizer extraction yield and the morphology changes of the PVC covering during the extraction procedure were investigated. Finally, the effects of the extraction conditions on the separation rate and purity of the recovered Cu and PVC during ball milling were evaluated. 2. Experimental section 2.1
Effect of plasticizer on physical and mechanical
The presence of high starch contents had an adverse effect on the mechanical properties of LDPE/starch blends. However, the addition of compatibilizer or plasticizer improved the interfacial...
- How does plasticizer affect the rheological properties of film-forming solution?
- Plasticizer influenced the rheological properties of film-forming solution. Plasticizer was efficient for the improvement of properties of blend film. The chitosan/zein film with PEG-400 exhibited superior properties.
- Do plasticizers affect the structural and physical properties of curdlan edible films?
- Conclusions This study investigated the effects of various plasticizers—glycerol (GLY), ethylene glycol (EG), propylene glycol (PRO), xylitol (XY), sorbitol (SOR), and polyethylene glycol (PEG)—on the structural and physical properties of curdlan (CL) edible films.
- Does plasticizer type affect chitosan/Zein film rheological and structural properties?
- The chitosan/zein film with PEG-400 exhibited superior properties. The purpose of this study was to evaluate the effect of plasticizer type (glycerol, PEG-400, and sorbitol) and concentration (0%, 15%, 30% and 45%, w /w dry polymer weight) on rheological and physico-mechanical and structural properties of chitosan/zein blend film.
- How do plasticizer effects affect physical-mechanical properties of solvent cast films?
- Plasticizer effects on physical-mechanical properties of solvent cast Soluplus® films Influence of equilibrium relative humidity and plasticizer concentration on the water content and glass transition of starch materials
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
- Should plasticizers be used with polymer matrices?
- The optimal use of plasticizers in combination with polymer matrices is highly desired to obtain films with acceptable physico-mechanical properties in terms of homogeneous texture, uniform appearance and flexibility.
