for esteri cation and production of ester plasticizers were initiated only recently and have good prospects, because they allow the reaction rate to be considerably increased and the amount of by-products and the plasticizer coloration to be decreased [15]. Ionic liquids can be readily separated and reused. In addition, many

Overall, global plasticizer consumption will grow at a rate of about 3.5% per year in the next few years. Phthalate esters, based on phthalic acid, are the main types of plasticizers used since they satisfy a broad range of processing and performance requirements, as well as a large number of markets.
- Where is polynt preparing a new esterification plant?
- To support their growth and demand, Polynt has started the process for the installation of a new esterification plant to produce Special Plasticizers, and among those mainly trimellitates, in its site in Atlacomulco (Mexico). The design and permitting activities will begin during H2 2022.
- When did plasticizers start?
- Later, in 1912, triphenyl phosphate was tested to substitute camphor oil, representing the beginning of the ester plasticizers era. Phthalic acid esters found applications as plasticizers for the first time in 1920 and continue to be the largest class of plasticizers in the 21st century .
- 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 .
- 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.
- What is a plasticizer in chemistry?
- The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
- Can plasticizers be used to make plastic products?
- The use of plasticizers for plastic products manufacture is not a new practice. Its application to modify polymer characteristics began in the 1800s. In these early days, manufacturers of celluloid or celluloid lacquers used natural camphor and castor oil for plasticization purposes, but these were unsatisfactory for many end uses.
