Ethylene Vinyl Acetate Copolymer Resin Eva

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.

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. Ethylene vinyl acetate copolymer resins sealing the deal our elvax ethylene vinyl acetate eva copolymer resins offer a variety of solutions for your sealants in meat and dairy packaging structures footwear wire and cable insulation as well as photovoltaic encapsulants and sheets.

Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. Evathene eva resins are ethylene vinyl acetate copolymers made by high pressure autoclave process. Both effects result in a lowering of the tg of the final copolymer. These material are used when a combination of softness toughness flexibility and polarity are needed.

Ethylene vinyl acetate eva copolymer resins. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below.

Ethylene vinyl acetate copolymer eva ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate. Resin for packaging adhesives film forming and molding resins hot melt adhesive uses advised against. Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications. 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. Eva copolymers are used in molded caps and seals footwear and car interiors. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c.

Having outstanding clarity gloss and weather resistance our nipoflex resins offer flexibility over wide temperature ranges as well as high impact strength elasticity and resistance to flex and environmental stress cracking.
