The Effect of Concentration and Type of Plasticizer on the
The Effect of Concentration and Type of Plasticizer 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
Effect of concentration and type of plasticizer on some
DOP, DOA, TTP, and Hex were used as plasticizers in concentration levels of up to 24% of PVC weight. The plasticized and unplasticized PVC were processed into sheets by compression molding. The sheets were tested for their vicat softening point, shore D hardness, flexural properties, and dynamic fatigue.
Effect of Plasticizer and Concentration on
The optimum concentration of glycerol addition affected the bioplastic characteristics with the best results were 40% concentration generate density of 0.836 g/mL, tensile strength of 0.818...
Plasticizer
The effect of plasticizers on elastic modulus is dependent on both temperature and plasticizer concentration. Below a certain concentration, referred to as the crossover concentration, a plasticizer can increase the modulus of a material. The material's glass transition temperature will decrease, however, at all concentrations.
Effect of Plasticizer Type and Concentration on Tensile
The use of starch based films as a potential alternative choice to petroleum derived plastics is imperative for environmental waste management. This study presents a new biopolymer (sugar palm starch) for the preparation of biodegradable packaging films using a solution casting technique. The effect of different plasticizer types (glycerol (G), sorbitol (S) and glycerol-sorbitol (GS
- Does plasticizer type and concentration improve film properties?
- The results obtained in this study showed that plasticizer type and concentration significantly improves film properties and enhances their suitability for food packaging applications. Content may be subject to copyright.
- Does increasing plasticizer concentration affect water absorption of plasticized films?
- On the contrary, density and water absorption of plasticized films decreased with increasing plasticizer concentration. Raising the plasticizer content from 15% to 45% showed less effect on the moisture content and water absorption of S-plasticized films.
- Does plasticizer concentration increase W/W?
- (15%–45% w/w). The results show that increasing the plasticizer concentration from 15% to 45% 8.514 × 10 −10 g·s−1·m−1·Pa−1 for GS-plasticized films. The plasticized films exhibited increased WVP values regardless of plasticizer type.
- Does plasticizer concentration affect thermal stability?
- insignificant effect on their thermal stability, regard less of plasticizer concentration. Comparing the than G- and GS-plasticized film s at temperatures below 300 °C. Figure 4.
- How does plasticizer concentration affect glass transition temperature?
- The glass transition temperature of SPS films slightly decreased as the plasticizer concentration increased from 15% to 45%. The plasticized films exhibited increased water vapor permeability values from 4.855 × 10−10 to 8.70 × 10−10 g•m−1•s−1•Pa−1, irrespective of plasticizer types.
- Do plasticizers affect the crystallinity index?
- X-ray Diffraction (XRD) To study the effect of different plasticizers in various concentrations on the crystallinity index, an XRD test was conducted. Figure 6 shows the crystalline peaks of plasticized wheat starch films. It shows that plasticized films have a lower crystallinity than the control film.
