DEVELOPMENT OF NEXT-GENERATION ESTER PLASTICIZERS FOR HIGH
are traditionally achieved through the addition of high performance ester plasticizers. While many of these plasticizers have been used in Vamac compounds to great effect in the past, the need for performance at higher temperatures necessitates the development of new materials to improve on permanence and volatility.
Development of New Generation of Ester Plasticizers for High
Due to the high post-cure and application temperature requirements few plasticizer have found utility in demanding AEM applications Polar monomeric plasticizer have good low temperature properties but suffer from higher weight losses during high temperature aging Polar high MW plasticizer have good permanence but lack optimal low
Synthesis of novel plasticizer ester end-capped oligomeric
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).

Among them, DPHP, produced from butene and 2-propylheptanol, is being rapidly developed because of its low-cost raw materials, abundant resources, and superior performance. DOP occupies almost 80% of plasticizer consumption in China. Due to the lack of domestic production of C 9 and C 10 alcohols, the development of high-carbon plasticizers is
18 Technical Ester plasticizers for high-temp AEM elastomers
Because of high temperature post-cure required by most acrylic elastomers and the higher maximum temperature of the application, only a few plasticizers show a reasonable degree of utility.3 Building on this fact, our goal is to pres - ent a new generation of high-perfor-mance ester modifiers and help expand
- 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 is a nonmigrating plasticizer?
- Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers. These materials may be produced in a simple process.
- 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.
- Are fatty acid alkyl esters plasticizers?
- In this context, a combination of numerous functionally active groups, e.g., methoxy, epoxy, acetoxy, thiirane, and aziridine on the fatty acyl chain of fatty acid alkyl esters have been developed and exploited as plasticizers (Kandula et al., 2017).
- How to improve the health and environmental issues concerning plasticizers?
- The use of environmentally-benign plasticizers is another way to improve the health and environmental issues concerning plasticizers. Among the number of factors that decide the feasibility of a substance to be used as a plasticizer, toxicological information is an increasingly important one.
- Should petroleum-based plasticizers be replaced with bioplasticizers?
- The substitution of petroleum-based plasticizers with bioplasticizers offers noteworthy advantages, such as recyclability, biodegradability, high lubricant power, low diffusion coefficients in the polymeric matrix and very low volatility.
