DEVELOPMENT OF NEXT-GENERATION ESTER PLASTICIZERS FOR HIGH
In this study, we evaluated several novel ester plasticizers in the new VMX 5000 series blend compounds consisting specifically of VMX 5015 and VMX-3040 (aka Vamac Ultra IP). This new blend of elastomers aims to push the maximum performance temperature of the compounds higher. Historically, plasticizers such as TP-759 and TegMeR 812 are

contribution. Ester plasticizers used for high performance applications must have excellent non-volatility upon heat aging and extraction resistance to various fluids. Measuring retention of low temperature properties after aging is an indicator of plasticizer permanence. In this paper, several elastomers are evaluated to show how choosing the

The information provided indicates that the permanence of the plasticizer is key to maintaining compound performance after extended exposure to high temperatures.

Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
- 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.
- 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.
- Which plasticizer is best for HNBR?
- The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR. As the graph depicts, a phthalate/adipate polymeric ester with a molecular weight of 1000 will enhance long-term heat aging properties. Fig. 3. Heat resistance of plasticized HNBR compounds Many plasticizers have been evaluated in HNBR for compatibility.
- 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.
