Vamac AEM
Ethylene Acrylic Elastomer
Compounds containing Vamac Ethylene Acrylic Elastomer (Vamac AEM) offer an excellent combination of temperature (high and low) and chemical resistance, along with exceptional compressive stress relaxation.
Product overview
AEM is formulated and processed by customers to meet their own specific performance requirements. It is available in a broad range of formulations to support multiple types of elastomers processing. Vamac AEM can improve performance for a wide range of specification targets. This often starts with customized formulations and expands to accommodate customers’ proprietary compounds.
Why Vamac AEM?Vamac Ethylene Acrylic Elastomers (AEM) can be made into cured compounds that have excellent resistance to high temperatures and good resistance to automotive fluids such as transmission fluids, engine oils, coolants, acidic condensates, urea solution, greases and new E-fluids. The low-temperature performance of Vamac AEM surpasses that of most other heat and oil-resistant polymers. Typical compounds meet OEM specifications for performance at –40 °C. Vamac AEM compounds can be designed to meet end-use requirements as low as –50 °C. End products based on Vamac AEM have excellent resistance to hot oils and hydrocarbon- or glycol-based lubricants, transmission fluids and power steering fluids. Low oil swell can be obtained with proper Vamac AEM grade selection and compounding. Vamac AEM shows good retention of properties and low permeation in new fluids for E-mobility (E-motor, E-transmission, Power electronics) and with dielectric fluids used to cool batteries. Please contact one of our experts at Celanese to request more information about Vamac AEM and the various product applications.
