Ethylene Vinyl Acetate Copolymer Resin Eva

Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications.

Ethylene vinyl acetate copolymer resin eva.

Chemical formula diagram. Resin for packaging adhesives film forming and molding resins hot melt adhesive uses advised against. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below.

Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. Both effects result in a lowering of the tg of the final copolymer. Eva copolymers are used in molded caps and seals footwear and car interiors. Evathene eva resins are ethylene vinyl acetate copolymers made by high pressure autoclave process.

Ethylene vinyl acetate eva copolymers are used in extrusion film processes for applications including packaging surface protection and greenhouse covers and in photovoltaic cell encapsulation. On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c. In addition poly vinyl acetate ethylene vae copolymers possess enhanced toughness flexibility and serviceability. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

They are mainly used for foaming coating extrusion and injection molding applications for many important industrial market segments such as shoe soles sheets wire and cable hot melt adhesive and solar cell encapsulation. Ethylene vinyl acetate copolymer eva properties and applications. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. These material are used when a combination of softness toughness flexibility and polarity are needed.

Ethylene vinyl acetate eva copolymer resins. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
