Ethylene Vinyl Acetate Eva

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

Ethylene vinyl acetate eva.

Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. In the solar industry the most common encapsulation is with cross linkable ethylene vinyl acetate eva. What are ethylene vinyl acetate eva films. Eva shows good barrier and stretch properties.

The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

Ethylene vinyl acetate offers good low temperature flexibility. Ethylene vinyl acetate eva layer film for laminated glass. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate. The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe.

It shows good chemical resistance. Eva films are a key material used for traditional solar panel lamination. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous.
