Selecting Plasticizers for Adhesives and Sealants
Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to the final bond and to provide improved low-temperature properties. However, plasticizers can also supply additional benefits that are important to both the formulator and end-user.
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 . TP-95. . 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

- 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 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.
- Which plasticizers are flame resistant?
- Flame-retardant plasticizers provide fire resistance to polymers such as PVC. A representative example is organophosphate. SANSO CIZER TCP (Tricresyl phosphate) is an organophosphate with excellent flame and weather resistance as well as electric insulation properties.
- 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.
