Ethylene Vinyl Acetate Eva

The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe.

Ethylene vinyl acetate eva. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Ethylene vinyl acetate eva market report provide the covid19 outbreak impact analysis of key factors influencing the growth of the ethylene vinyl acetate eva market size production value and consumption. What are ethylene vinyl acetate eva films. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Ethylene vinyl acetate is a flexible and transparent thermoplastic. It shows good chemical resistance. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate. Eva is the abbreviation for ethylene vinyl acetate. Ethylene vinyl acetate offers good low temperature flexibility.

The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. In the solar industry the most common encapsulation is with cross linkable ethylene vinyl acetate eva. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. Eva shows good barrier and stretch properties.
