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.
18 Technical Ester plasticizers for high-temp AEM elastomers
All materials were aged in hot air ovens at 190°C for two weeks, three weeks, and four weeks. Due to the weight and volume loss we noticed in the control compound without the plasticizer, we normalized the losses in the other compounds to show losses from plasticizer alone. These results are shown in Figs. 1 and 2. The assumption was that normal -
TP-95 | Hallstar Industrial
TP-95 is a highly compatible plasticizer that has been especially designed to impart maximum low temperature flexibility to elastomers, in particular high ACN nitrile, urethanes, polyacrylates and epichlorohydrin rubbers. TP-95 can also be using in vinyl formulations, either alone or in combinations with other plasticizers.

- Are elastomer plasticizers good for rubber?
- Traditional elastomer polymers, such as nitrile, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, have for years used moderate- to low-performance ester plasticizers. However, longevity requirements for rubber articles made from these elastomers have created a need for higher-performance ester 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.
- 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.
- Are plasticizers and elastomers compatible?

Plasticizers and elastomers need to be compatible with each other b sed on having similar polarities.The Plasticizer/Polymer Polarity Chart on page 22 graphically shows the relationship between compatibility and p Rubber (NBR)POLYMER INFORMATIONNitrile elastomers (NBR) result from reactions of butadiene
- What factors affect Plasticizer-elastomer interaction?
- 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. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties.
