Reactive Ester Plasticizer for Elastomers - Hallstar Industrial
In this study, a reactive ester is compared to high-performance traditional esters in various elastomers. Heat aging, hydrocarbon fluid immersion (i.e.; oils and fluids) and hexane extraction tests show not only the permanence of the reactive esters but also that these esters provide the low-temperature flexibility required by many rubber

www.rubbernews.com Rubber & Plastics News August 22, 2016 15 Technical Evaluating synthetic and renewable esters By Stephen O’Rourke Hallstar Co. Plasticizers are the most important additives to elastomers and plastics from the standpoint of cost and effect. Plasti-cizers extend the range of usefulness of elastomers and allow them to meet the
- 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.
- Are ester plasticizers good for polar elastomers?
- Ester Plasticizers for Polar Elastomers with Emphasis on Low-TemperatureEster plasticizers contribute processing advantages to rubber compounds made with polar lastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compoun
- 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.
- 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.
- 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?
- the properties of that elastomer. 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
