Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
Effects of Plasticizers on Mechanical Properties, Oxygen
Tensile strength and elastic modulus of films were decreased when adding plasticizers, whereas elongation at break were increased. Therefore, it caused an increase in oxygen permeability of...
What Plasticizers Do & How They Affect Properties | Osborne
Plasticizers act like a lubricant among polymer chains to reduce rigidity. Without them, synthetic polymer materials would be too brittle and rigid for any practical purpose. For example, plasticizers give rubber its extensibility. Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC.
Combined effects of plasticizers and D-lactide content on the
It means that the effect plasticizers have on toughness may differ depending on the D-lactide content of the PLA. In this paper, we studied the combined effect of the D-lactide content of the PLA and the commonly used oligomer lactic acid and dioctyl adipate plasticizers on the mechanical properties and morphology of PLA.
10. EFFECT OF PLASTICIZERS ON PROPERTIES
As expected for a plasticized polymer, 23 by increasing the plasticizer content ( Figure S1), melting temperature values slightly decreased, and crystallization temperature T c was seen to...
- Do plasticizers soften thermomechanical properties?
- The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
- 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
- What are the effects of plasticizer in film production?
- For instance, inadequate or excessive use of plasticizer in films may lead to improper film formation, partial or full phase separation eventually leading to poor or unacceptable quality. In addition, disintegration time of ODFs is important, as it may significantly affect drug release and thereafter absorption and bioavailability.
- Does plasticizer affect the disintegration of pullulan films?
- The hydrophilic nature of pullulan seems to have dominated over the plasticizer effects in concentrations range studied, facilitating rapid disintegration of films. Thus, this study indicates that plasticizer can only influence the flexibility and mechanical properties of pullulan films but not their disintegration.
- How do plasticizers affect film forming temperature?
- Plasticizers lower the minimum film forming temperature, facilitate formation of soft and flexible film through changes in glass transition temperature (T g) and allows inter-intra molecular interactions such as hydrogen bonding between polymer and plasticizer.
- Do biodegradable plasticizers affect thermal and mechanical properties of poly(PHBV)?
- The effects of biodegradable plasticizers on the thermal and mechanical properties of poly (3-hydroxybutyrate- -3-hydroxyvalerate) (PHBV) were studied using thermal and mechanical analyses. Soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were used as plasticizing additives.
