Ester Plasticizers for Polyvinyl Chloride - Springer
2O 3, SnO 2, TiO 2, ZrO 2, etc.) are of much interest as esteri cation catalysts. The acid-ity of such systems is very high, exceeding even that of 100% sulfuric acid. Yanfei et al. [15] analyzed the use of solid superacids, sulfonium anion-exchange resins, heteropoly acids supported on zeolites, ionic organome-
Synthesis and Properties of 3-Azido-2,2-bis(azidomethyl
This study reports the synthesis and characterization of a novel azido ester plasticizer, 3-azido-2,2-bis(azidomethyl)propyl 2-azidoacetate (ABAMPA), with good yield and high purity. The density, impact sensitivity, friction sensitivity, thermal decomposition temperature and glass transition temperature were determined to be 1.326 g cm -3

Marta Lenartowicz-Klik, in Plasticizers Derived from Post-Consumer PET, 2025. 4.2.2 Esters of Succinic and Citric Acid. New technological solutions in the synthesis of acids and alcohols from renewable raw materials are the basis for the production of bioplasticizers that constitute an alternative to their phthalate counterparts.
Synthesis and properties of a bio-based PVC plasticizer
The use of non-toxic and biodegradable alternatives to replace phthalates has become an inevitable trend. 25–27 Currently, hundreds of plasticizers obtained from renewable bio-based resources have been commercially used, such as epoxy soybean oil plasticizer, 28,29 epoxidized glycidyl ester of ricinoleic acetic ester, 30 epoxidized tung oil
Plasticizers Derived from Biomass Resources: A Short Review.
Hydroxyl and nitrogen rich group-containing tung oil-based ester (GEHTMA-1, GEHTMA-2, GEHTMA-3 and GEHTMA-4) plasticizers are prepared and used to replace dioctyl terephthalate (DOTP) . Figure 17 and Table 1 h,i,j show synthesis route and their chemical structure. GEHTMA-3 displays better mechanical properties and endows PVC resins with well
- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost/performance evaluation. 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.
- How to choose a high-performance ester plasticizer?

- Why do we use ester plasticizers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interaction is governed by many factors, such as solubility parameter, molecular weight and chemical structure. Ester plasticizers are selected based upon cost/performance evaluation.
- 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.
- 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.
- Are plasticizers suitable for elastomers and high-temperature polymers?
- Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers.
