An Introduction to Vinyl Acetate-Based Polymers

Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is a copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) … See more EVA is made by mixing ethylene and vinyl acetate in a processor, which creates an unrefined mass of EVA. It is fed through rollers that flatten it into sheets, which are then put into a pressure oven. See more Polyethylene vinyl acetate has recently become a popular alternative to polyvinyl chloride because it does not contain chlorine.
