Ethylene Acrylic (AEM)/Vamac®

Ethylene acrylic compounds provide excellent high heat aging resistance to 347°F (175°C) while providing good physical properties. A high degree of oil, ozone, UV, and weather resistance along with good low temperature flexibility are also ethylene acrylic attributes.
