Compounds - Ethylene Acrylic (AEM)

Ethelyene Acrylic

Vamac MaterialEthylene 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 Etheylene Acrylic (VAMAC®) materials.

Names: VAMAC®, AEM, Etheylene Acrylic
