Effect of plasticizers and polymer blends for processing
Plasticizers depress the glass transition temperature (T g) of polymers and produce a flowable material at lower temperatures. The use of plasticizers to depress T g of lignin is important, since at high processing temperatures lignin crosslinks, making it intractable.

Plasticiser loss from plastic or rubber products through diffusion and
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
Comparative Effect of Different Plasticizers on Barrier
Purpose Identifying ideal plasticizer is pivotal to develop a biopolymer-based edible films for food packaging. The effect of different plasticizers (glycerol, polyethylene glycol, sorbitol) on the mechanical, water vapor barrier, optical, and moisture sorption properties of hydroxypropyl methylcellulose (HPMC) -based flexible films was examined in this study. Methods Mechanical properties and
Plasticizers Market Size, Growth Rate, Latest Trends, Forecast, 2030
Pune,India, April 17, 2025 (GLOBE NEWSWIRE) -- The global plasticizers market size is expected to gain momentum owing to the increasing demand for flexible polymers during the forecast period.
- Do different plasticizers affect mechanical properties of soy protein bioplastics?
- Some authors have studied the effect of different plasticizers in soy protein bioplastics, like Wang et al. (1996) that focused on the effect of glycerol, ethylene glycol, polyethylene glycol, propylene glycol, and 1, 3-propanediol on the mechanical properties of compression moulded samples.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- How do plasticizers affect processing?
- Plasticizers can influence processing by inducing lower viscosity, faster filler incorporation, easier dispersion, lower power demand and less heat generation during processing, better flow, improved release and enhanced building tack.
- Can -lactoglobulin films be plasticized with different plasticizers?
- The addition of combined plasticizers (GLY and PEG) can modify the mechanical properties and water vapor permeability . β-Lactoglobulin films were plasticized with different plasticizers (PG, GLY, sorbitol, PEG 200, PEG 400 and sucrose) aiming at improving the mechanical properties.
- 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.
