Ethylene Acrylic, widely known as Vamac® is favored in applications where chemical and heat resistance are desired. Vamac®, an ethylene and methyl acrylate copolymer, has properties similar to polyacrylate. It exhibits an extended low temperature limit and better mechanics than that of polyacrylate.
Both o-rings and gaskets can be made from Ethylene Acrylic (VAMAC®) materials.
Names: VAMAC®, AEM, Ethylene Acrylic
