Ester-plasticizers-for-high-temp-AEM-elastomers | Rubber News
Ethylene acrylic elastomers traditionally have been used in applications requiring high level of performance under extreme temperature conditions. They are typically used in a wide variety of automotive applications, such as turbo chargers, oil cooler hoses, seals and gaskets. To Continue Reading...

18 Technical Ester plasticizers for high-temp AEM elastomers
Recent advancements in ethylene acrylic elastomers by DuPont have pushed this performance to higher temperatures and longer periods of time through their Vamac-brand VMX 5000 series of polymers. Low temperature improvements, however, are traditionally achieved through the addition of high performance ester plasticizers. While many of these plasti -
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Hallstar esters provide improvement for a range of parameters including: low temperature flexibility, volatility resistance, extraction and migration resistance. Products are available in both liquid as well as dry liquid concentrate form for easier handling and improved dispersion. We strive to stay ahead of market trends and new polymer launches.
