Is eva an olefin
WebApr 10, 2024 · EVA markets have seen significant price increases due to increasing demand and limited supply of vinyl acetate monomer. Specialty products offer stable earnings during the time of economic slow-down and in times like today when the commodity markets will face more competition from cost-advantaged products from the Middle East. 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) content and the way the materials are used.
