DEVELOPMENT OF NEXT-GENERATION ESTER PLASTICIZERS FOR HIGH
of plasticizer while maintaining Shore A hardness by changing the polymer ratio. The larger quantity of plasticizer helps to emphasize and differentiate performance between different plasticizer compounds. Therefore, for the second part of our study the following formulation was adopted: Material Wt (phr) % in the formula Vamac Ultra IP a 36
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).

Recent advancements in ethylene acrylic elastomers by DuPont have pushed this performance to higher temperatures and longer periods of time through their Vamac-brand VMX 5000 series of polymers. Low temperature improvements, however, are traditionally achieved through the addition of high performance ester plasticizers.

High Performance Ester Plasticizers for Hose Compounds
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 seven to eleven carbons in length. Ester plasticizers are commonly used only for their as-molded low temperature contribution. Ester plasticizers used for high
- 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.
- 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.
- 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.
- Do plasticizers have a low fogging value?
- In the case of PVC artificial leather, plasticizers make up the vast majority proportion of volatile substances; therefore, the automobile industry calls for plasticizers with extremely low volatility, or specifically, a low fogging value. Among all commercial bio-plasticizers, few can fulfil this requirement as well as DIDP.
- Does epoxidized fatty acid tri-esters bio-plasticizer reduce efame?
- Governed by the interplay between two extra polar, PVC-compatible short esters and higher molecular weight relative to ordinary EFAME, the fogging value of the resulting epoxidized fatty acid tri-esters bio-plasticizer was found to reduce to a level comparable to DIDP.
- 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.
