Ethylene vinyl acetate copolymer resin.

Ethylene vinyl acetate copolymer eva properties and applications. Ethylene vinyl acetate copolymer eva ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate. Both effects result in a lowering of the tg of the final copolymer. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.

These material are used when a combination of softness toughness flexibility and polarity are needed. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. 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. 24937 78 8 ethylene vinyl acetate eva ethylene vinyl acetate copolymer ethylene vinyl acetate polymer 1 2.

Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. In addition poly vinyl acetate ethylene vae copolymers possess enhanced toughness flexibility and serviceability. 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. Chemical formula diagram.

Ethylene vinyl acetate eva copolymer resins. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications.

Ethylene vinyl acetate eva copolymer cas no. In the last two published papers the influences of wax and asphaltene content on the synergistic performance of ethylene vinyl acetate eva copolymer together with resin stabilized asphaltenes on the flow behavior improving of model waxy oil were systematically investigated and a relevant mechanism has been proposed. Evathene eva resins are ethylene vinyl acetate copolymers made by high pressure autoclave process. Relevant identified uses of the substance or mixture and uses advised against.
