Ethylene Vinyl Acetate Eva

Ethylene vinyl acetate eva layer film for laminated glass.

Ethylene vinyl acetate eva.

The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Eva is the abbreviation for ethylene vinyl acetate. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. It shows good chemical resistance. In the solar industry the most common encapsulation is with cross linkable ethylene vinyl acetate eva. Eva shows good barrier and stretch properties.

Ethylene vinyl acetate offers good low temperature flexibility. 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. 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.

As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. Eva films are a key material used for traditional solar panel lamination. What are ethylene vinyl acetate eva films.
