NEW POLYMERIC ESTERS FOR LOW POLARITY ELASTOMERS - ResearchGate
Currently, plasticizers for these low polarity elastomers are limited to inexpensive process oils, including napthentic, paraffinic, and other petroleum-based products, and low molecular...
Ester Plasticizers for Polar Elastomers with Emphasis on Low-Temperature
Ester Plasticizers for Polar Elastomers with Emphasis on Low-Temperature Ester plasticizers contribute processing advantages to rubber compounds made with polar elastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compounding material used to enhance the deformability of a polymeric compound."
“New Line of Modifiers for Low Polarity Elastomers and Plastics”
This paper discusses ester-based additives to improve the properties of a number of low polarity polymers. These include elastomers like EPDM, Natural Rubber, Polychloroprene and polyolefins. Blends of thermoplastics with elastomers, thermoplastic alloys, are also targeted.
Plasticizer Selection for Elastomers - Chemceed
Both monomeric and polymeric ester plasticizers are compatible with AEM. DOS and DOP can be used to impart low-temperature flexibility, but can only be used in temperatures up to 125°C. Polymeric plasticizers are recommended for better permanence and higher continuous use temperature applications.

- Are ester polysiloxane elastomers oil-resistant?
- In this study, we sought to construct an ester polysiloxane (EPS) elastomer with a highly flexible alternating arrangement of silicon atoms and oxygen atoms as the backbone and polar ester groups as the side group to expect the elastomer with low-temperature and oil-resistant performance.
- 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.
- Which polymers require high polarity plasticizers?
- with sulfur or peroxide systems. High ACN polymers require high polarity plasticizers, low ACN polymers equire low polarity plasticizers. Polymerics used at greater than 15 PHR are generally us ISTANCE T IL AND F SUCH AS: Adhesives Bla rs Conve belts and rolle Diaphragms Fuel cell liners Fuel es and es (cove and tubes) skets
- Are polar elastomers oil resistant?
- Unfortunately, the introduction of these highly polar groups or atoms is hard to construct oil-resistant elastomers that possess good low-temperature performance. To date, the only elastomers resistant to non-polar oils and sufficient for service below −50 °C are fluorosilicone rubbers [26, 27].
- Which polymeric plasticizer is more polar?
- ers The higher the sap value, the more polar the polymeric plasticizer. PARAPLEX G-30 was expected to have a potentially greater compatibility p blem than PLASTHALL P-550, because of its low viscosity and sap value. It might not be compatible with highly polar NBR, 38% [-CN]. PLASTHALL P-550 has been shown to
