Ethylene Vinyl Acetate Copolymer Resin

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.

Ethylene vinyl acetate copolymer resin. Ethylene vinyl acetate eva copolymer cas no. On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c. 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.

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. 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. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. Ethylene vinyl acetate copolymer eva ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate.

Ethylene vinyl acetate copolymer eva properties and applications. Both effects result in a lowering of the tg of the final copolymer. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor.

Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. 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. These material are used when a combination of softness toughness flexibility and polarity are needed.

Here the effects of vinyl acetate va content 12 40 wt on the. Resin for packaging adhesives film forming and molding resins hot. Evathene eva resins are ethylene vinyl acetate copolymers made by high pressure autoclave process. Ethylene vinyl acetate eva copolymer resins.

Relevant identified uses of the substance or mixture and uses advised against. 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.
