Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887

Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.
Role of Plasticizers in PVC Products | Bausano
A plasticizer is a substance, liquid or solid, incorporated in a polymer to increase its flexibility, workability or distensibility. A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Suspension PVC (S-PVC) process is the common method to manufacture PVC: PVC obtained in the form of particles with size 50-200 microns Lower flexible PVC formula costs PVC particles obtained are mixed with plasticizers & can be extruded in pellets which are further used for processing via extrusion, calendaring, injection molding…
- What are plasticizers used in PVC & other plastics?
- Plasticizers used in PVC and other plastics are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. These compounds are selected on the basis of many critieria including low toxicity, compatibility with the host material, nonvolatility, and expense.
- What are plasticizers for polymers?
- Plasticizers for polymers are either liquids with low volatility or solids. According to 2017 data, the total global market for plasticizers was 7.5 million metric tonnes.
- What are the characteristics of polymeric plasticizers?
- Polymeric plasticizers: their main characteristic is the high migration resistance (both in contact with oils, fats and hydrocarbons, and with thermoplastic materials), a good resistance to high temperatures and a low volatility.
- Are lignin naphthalene and melamine sulfonate superplasticisers organic polymers?
- Lignin, naphthalene, and melamine sulfonate superplasticisers are organic polymers. The long molecules wrap themselves around the cement particles, giving them a highly negative charge so that they repel each other.
- How does plasticizer affect the mobility of a polymer chain?
- The mobility of a polymer chain is more complex in the presence of plasticizer than what the Flory–Fox equation predicts for a simple polymer chain. The molecules of plasticizer take control over mobility of the chain - a polymer chain does not show an increase of the free volume around polymer ends.
- What are plasticizers & superplasticizers?
- In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improved workability and strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
