In addition poly vinyl acetate ethylene vae copolymers possess enhanced toughness flexibility and serviceability.
Ethylene vinyl acetate copolymer resin.
Ethylene vinyl acetate copolymer eva ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate.
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.
It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
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.
Here the effects of vinyl acetate va content 12 40 wt on the.
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.
Chemical formula diagram.
Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below.
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 eva copolymer cas no.
Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.
It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor.
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.
Ethylene vinyl acetate copolymer eva properties and applications.
Resin for packaging adhesives film forming and molding resins hot.
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.
There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.
Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.
On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c.
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.
