Ester plasticizers used for high performance applications must have excellent non-volatility upon heat aging and extraction resistance to various (Fig. 1) of the production of an acid, alcohol
Another feature that sets the two processes apart is the raw material used. The esterification process is carried out directly through the reaction of terephthalic acid with 2-ethylhexanol (PTA + 2EH), in which water

Sucrose ester production (the second stage process). Methyl laurate obtained from the rst stage (or pure methyl laurate) and sucrose were mixed in DMSO to obtain a homogeneous solution. e ratio was
This phenomenon is a driving force of this process, shifting the equilibrium toward the product formation. As a result, dialkyl succinates and adipates were obtained in high product isolation as well as a high yield and purity of the resulting esters. These advantages make the production of green plasticizers. 2. Materials and Methods 2
- How to choose an ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will help in selecting an ester plasticizer. ASTM D883, "Plastics Nomenclature," American Society for Testing and Materials, Philadelphia, PA.
- How are plasticizers made?
- Considering most of the commercially important plasticizers are esters produced by the reaction between a carboxylic acid or acid anhydride and organic alcohols, in the following, the typical steps and conditions of their production processes will be briefly described: 1.
- Why are ester plasticizers important for elastomers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interactions are governed by many factors, such as solubility parameter, molecular weight and chemical structure.
- Do fluorocarbon elastomers accept ester plasticizers?
- Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- What are the basic chemical structures of polyester plasticizers?
- Basic chemical structures of polyester plasticizers Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters.
