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

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.
Effects of plasticizer type and concentration on rheological
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.
Effect of plasticizer type and concentration on
Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility. On the contrary, density and water absorption of plasticized films decreased with...
- How volatile is the plasticizers market?
- With such a diverse range of applications, the plasticizers market can be volatile as it reacts to consumer trends, seasonality and regional supply. Buyers, sellers and traders must act quickly to make the most of market opportunities. This means constant access to the most current prices and data is key.
- Why are plasticizer prices rising in Asia-Pacific?
- Asia The price trend for plasticizers showed an upwards trend in the the Asia-Pacific region during the first quarter owing to the domestic polymer segment's increased demand for the product as a result of better offtakes from China’s construction sector.
- How do plasticizers affect a polymer?
- Plasticizers are expected to reduce the modulus, tensile strength, hardness, density, melt viscosity, glass transition temperature, electrostatic chargeability and volume resistivity of a polymer, while at the same time increasing its flexibility, elongation at break, toughness, dielectric constant and power factor .
- Why did plasticizer prices rise sharply in Q1 2022?
- Plasticizers prices rose sharply in Q1 2022 as a result of the sharp rise in crude oil prices and improved downstream demand. The price of dioctyl phthalate averaged 1875 USD/MT towards the end of first sector. The increase in upstream value prices and the strengthening domestic market demand were the main factors influencing this price shift.
- Why are plasticizers so popular?
- By creating viscosity, flexibility, softness and other properties to finished products, plasticizers are in demand from multiple manufacturing sectors for everything from automotive components to medical equipment, packaging and toys.
- Does plasticizer deteriorate thermomechanical properties?
- The plasticizer industry has grown with the use of plastics worldwide. Recent plasticizer research has focused on technological challenges including leaching, migration, evaporation and degradation of plasticizers, each of which eventually lead to deterioration of thermomechanical properties in plastics.
