Ester Plasticizers for Polyvinyl Chloride - Springer
plasticizers were produced using, as a rule, acid catalysts (mainly sulfuric acid and also benzene- and p-toluene-sulfonic acids) [2]. Despite high performance and low cost, sulfuric acid practically is not used at modern en-terprises for the following reasons: occurrence of such side processes as dehydration of alcohols to ole ns and
Synthesis of novel plasticizer ester end-capped oligomeric
Furthermore, compared with ATBC and DOTP, EOLs showed better migration resistance in the leaching test. All test results showed that the comprehensive performance of EOLs was better than those of commercial green plasticizers ATBC and DOTP, which provided a new method for the development of novel green plasticizers.

High-performance liquid chromatography was used for lactic acid and acetic acid determination. Concentrations of 90 and 60 mg/mL, respectively, were reported. Reducing sugars in MEF were also determined according to the Cuban Standard NC-712: 2009; Final molasses—determination of total reducing molasses by the Lane–Eynon method at constant volume.
US5880310A - Process for producing plasticizer esters
Provided is a process for producing a plasticizer ester characterized by previously removing dissolved oxygen in a starting alcohol, and then subjecting an organic acid or its anhydride and...
What Plasticizers Do & How They Affect Properties | Osborne
In the past sixty years, over 30,000 different plasticizers have been developed worldwide. Performance, availability, cost-effectiveness, along with health and environmental regulations, has limited a small portion, approximately 50, for commercial usage. Of these, varying types of esters are the more commonly used plasticizers.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- How to choose a high-performance 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 contribute to the selection of a high-performance ester plasticizer. 1.
- Can polymeric esters enhance a high-performance elastomer?
- One example of how polymeric esters can enhance a high-performance elastomer is depicted in Figure 3. High-saturated nitrile is used in many high-heat applications. The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR.
- Do epoxidized benzyl esters provide flexible PVC films?
- Epoxidized benzyl esters provided flexible PVC films with favorable properties. The objective of this study was to produce new and renewable bio-based plasticizers from used soybean cooking oil (USCO). First, USCO was completely converted into free fatty acids (FFAs) using lipase from Candida rugosa.
- What is a safe plasticizer substitute for phthalate esters in PVC?
- Of all these options, vegetable oils (refined or used) and their derivatives, like fatty acid alkyl esters (biodiesel) and free fatty acids, are some of the most promising raw materials for producing safe plasticizer substitutes for toxic phthalate esters in PVC and other polymers [7, , , , ].
