window for end use temperatures. A compound with no plasticizer has a temperature window of –40 °C up to 165 °C and the compound can withstand short term temperature spikes up to 200°C. The low temperature properties can be improved by the addition of a plasticizer, and with 20 phr of plasticizer the initial Tg is about –54 °C. The cured
Phthalate-Free High Efficiency Plasticizer Improved
DOWANOL LoV 485 Glycol Ether Dow has introduced a phthalate-free, P-Series glycol ether ester to enable optimal plasticizer performance and meet evolving demands of end-use customers. DOWANOL LoV 485 Glycol Ether displays superior plasticizing properties with high-performance acrylic sealant binders compared to industry standard phthalates
Designing anti-migration furan-based plasticizers and their
The structure of these furan-based plasticizers contain furan ring, ether and ester groups. The introduction of furan ring helps plasticizers improve compatibility with the polar PVC. Meanwhile, the introduction of ether and ester group can reduce the melting point of FDCA esters and help to improve flexibility, oil resistance.

of plasticizer while maintaining Shore A hardness by changing the polymer ratio. The larger quantity of plasticizer helps to emphasize and differentiate performance between different plasticizer compounds. Therefore, for the second part of our study the following formulation was adopted: Material Wt (phr) % in the formula Vamac Ultra IP a 36
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
- Which polyether-ester plasticizer has a high heat resistance and low-temperature performance?
- The results showed that among the rubber compounds containing the four polyether-ester plasticizers, the compound with PBADME demonstrated superior heat resistance and low-temperature performance. Specifically, the PBADME-containing compound exhibited a TR 10 temperature of −39.9°C and a brittleness temperature of −54°C.
- How are polyether ester plasticizers synthesized?
- ABSTRACT Four polyether ester plasticizers containing both ester groups and ether bonds were synthesized using 1,4-butanediol, adipic acid, and alkyl ether alcohols as raw materials. By varying the...
- 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.
- Which plasticizer is best for acrylic elastomers?
- Table V highlights data from this study conducted by DuPont Dow Elastomers L.L.C. ®. DBEEEG, a high molecular weight glycol ether ester monomeric plasticizer, is commonly recommended for acrylic elastomers. In this study, A-1000A and A-1000B show they are equal or better than DBEEEG at softening efficiency and original low temperature.
- 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.
