A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was very stable.
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).
Combining Renewable Eleostearic Acid and Eugenol
In this study, two kinds of sustainable plasticizers (eleostearic acid eugenol ester (EAEE) and epoxidized EAEE) were synthesized to plasticize PVC films using eleostearic acid and eugenol. Compared to EAEE, PVC plasticized with epoxidized EAEE showed more flexible and thermal stability.
Synthesis of novel plasticizer ester end-capped oligomeric
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

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
- 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 are polyether ester plasticizers synthesized?
- ABSTRACT Four polyether ester plasticizers containing both ester groups and ether bonds were synthesized using 1,4-butanediol, adipic acid, and alkyl ether alcohols as raw materials. By varying the...
- 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.
- 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.
- Which elastomers use polymeric esters?
- Polymeric esters are especially suited for high performance elastomers, such as nitrile, high saturated nitrile and polyacrylates. Polymeric esters also have found utility in chlorinated polyethylene, chlorosulfonated polyethylene and fluoroelastomers.
