August 22, 2016 15 Technical Evaluating synthetic and renewable esters
Chlorinated polyethylene, epichlorohy- drin, acrylic and hydrogenated nitrile will accept the highly polar plasticizers, but with service temperatures ranging up to 350 F, use lesser quantities and allow a more limited plasticizer choice because of plasticizer volatility characteristics.
Urethane/Rubber Plasticizers - DIC Corporation
Monocizer W-260 is a low viscosity etherester plasticizer, W-262 is a polyetherester plasticizer, and Polycizer W-320 is a low viscosity polyester plasticizer. All excel in workability, cold resistance, and plasticization efficiency, and possess superior capabilities compared to phthalate ester DEHP (DOP).
18 Technical Ester plasticizers for high-temp AEM elastomers
Ester plasticizers for high-temp AEM elastomers Acrylic elastomers are used in applica-tions requiring continuous service up to 175°C and intermittent exposure to ex-tremely high temperatures of up to 200°C. 1 the past year, These elastomers are considered lower-cost alternatives to other high-temperature elastomers, such as fluoroelastomers

High Performance Ester Plasticizers for Hose Compounds
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 seven to eleven carbons in length. Ester plasticizers are commonly used only for their as-molded low temperature contribution. Ester plasticizers used for high
- What is a reactive ester plasticizer for elastomers?
- Reactive Ester Plasticizer for Elastomers Stephen O’Rourke, Technical Director, Industrial Ester plasticizers are traditionally used to provide low temperature and improved processing of elastomers. New esters have been designed recently to improve the permanence of these materials when subjected to high heat and fluid extraction.
- 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
- How do I Choose an ester plasticizer?
- A610), can be found on pages 7-8.When selecting an ester plasticizer, it is important to consider which elastomer is being used and the properties of that elastomer. Plasticizers and elastomers need to be compatible with each other b
- How much reactivity is bonded to the elastomer?
- Based on our results in HNBR, our conclusion is that approximately 60–70 percent of the reactive ester actually was bonded with the polymer. In addition, it is quite apparent that the choice and level of peroxide is critical in maximizing the reactivity of the ester to the elastomer.
- What are external plasticizers?
- External plasticizers are materials that interact physically with the elastomer but are not chemically reacted with the polymer. Solvent and non-solvent are two distinct types of external plasticizers. Common esters and polymeric polyesters are both external and physical plasticizers.
- What is a standard monomeric plasticizer?
- he following:Standard Monomericsare typically low molecular weight, general purpose products offering a good balance of performance properties for on-critical end use applications. These plasticizers generally fall under our Plasthall® trade name, suc
