Synthesis of novel plasticizer ester end-capped oligomeric lactic acid
In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).
Minimizing the Effect of Plasticizer Supply Disruptions - GEON
Recognizing a shortage of 810 alcohol was imminent and would affect 810TM plasticizer supply, GEON’s cross-functional Synthetic Esters team proactively began developing a replacement plasticizer. When the formulator reached out to GEON with their dilemma, the team was already prepared with a solution.
Synthetic esters - NYCO
High performance esters for the latest generation of synthetic lubricants. The need for high-duration lubricants in environments where temperatures are constantly rising, along with requirements for improved cleanliness and optimized energy efficiency is pushing industrial consumers towards the usage of synthetic esters.

- How phthalate ester plasticizers are extracted from plastic devices?
- Plasticizers from plastic devices: extraction, metabolism and accumulation by biological systems Migration of phthalate ester plasticizer from poly (vinyl chloride) blood bags into stored human blood and its localization in human tissues
- What are the different types of plasticizers?
- Trimellitates, paraffinic sulfonic acid and phenyl esters, polyesters, chlorinated hydrocarbons, aliphatic/aromatic monocarboxylic acid esters such as benzoates, and a variety of elastomers have also been used as plasticizers for years. Plasticizers continue to evolve with the demand of specialty applications.
- Which plasticizers are used for EC-based coatings?
- Triethyl citrate (TEC) and dibutyl sebacate were used as reference plasticizers. Due to the excellent mechanical properties (a tough film structure with considerable flexibility) and low permeability of the plasticized films, both the n -ASAs, especially OSA, proved to be ideal plasticizers for EC-based coatings at 30 wt% or higher concentrations.
- What are phthalate esters used for?
- Phthalate esters have been used extensively in thermoplastic cellulose ester molding compounds, PVC and other vinyl chloride copolymers for over 60 years. Phthalates account for 92% of plasticizers produced worldwide while DEHP represents 51% of the phthalates .
- Are plasticizers biodegradable?
- Plasticizers are used for biodegradable plastics as well. There are more stringent requirements on these plasticizers, though, since by definition they will be released to the environment during normal product use.
- What makes a good plasticizer?
- Ideal plasticizers should be highly compatible with polymers, stable in both high and low temperature environments, sufficiently lubricating over a wide temperature range, insensitive to solar ultraviolet (UV) radiation, leaching and migration resistant, inexpensive and should fulfill health and safety regulations.
