Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.

Plasticizers Derived from Biomass Resources: A Short Review
These bio-based plasticizers mainly include epoxidized plasticizer, polyester plasticizer, macromolecular plasticizer, flame retardant plasticizer, citric acid ester plasticizer, glyceryl ester plasticizer and internal plasticizer.
Soft PVC foams: Study of the gelation, fusion, and foaming processes
Several plasticizers {Mesamoll (alkylsulfonic phenyl ester), Eastman 168 [bis(2‐ethylhexyl)‐1,4‐benzenedicarboxylate], Hexamoll [di(isononyl) cyclohexane‐1,2‐dicarboxylate], Citroflex A4 acetyl tributyl citrate (ATBC), and Plastomoll (dihexyl adipate)} were found to be interesting alternatives in the production of soft PVC foams because they provided very good quality foams with
- What is a citrate plasticizer?
- Citrate plasticizers are made of citrates which are esters of citric acid. They can be found in oily liquid form and they are practically colourless and odourless. They are used in paints, coatings and inks but also in food packaging products, cling wrap, toys and medical applications.
- Which materials can be plasticized with citrates?
- Some properties of materials plasticized with citrates can match those plasticized with DOP but the cost of their production is substantially higher. Tri Butyl Citrate is a high boiling substance, is used as a solvent and plasticizer for polymers especially for PVC and its copolymers which are subsequently applied to food wrapping film.
- Why are citrate plasticizers not used in film applications?
- However, citrate plasticizers are highly volatile and a significant amount is lost due to this property. Citrates lack permanency. Hence, they are not employed in resilient applications like cables, flooring, or roofing. They induce more fogging in film applications.
- Which citrate esters are used as plasticizers in ca?
- Other citrate esters reported as plasticizers in CA are tributyl citrate (TBC) and acetyl tributyl citrate (ATBC) , . When ATBC was used in CA, white and opaque films were obtained by casting. Further DSC analysis demonstrated the presence of a crystalline peak.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What are citrate esters used for?
- They have been used mainly as plasticizers with cellulosics, PVC, polyvinyl acetate, and other polymers used in medical plastics and food contact packaging. Some citrate esters find specialty use in blood bags and food wraps. Citrates are also used in toys produced by the plastisol process.
