Advantages Of Ethylene Vinyl Acetate

For example flexibility adhesion and water resistance can be adjusted as needed by varying the monomer composition.

Advantages of ethylene vinyl acetate.

Emblem in packaging technology 2012. This chemical is primarily used as a raw material in the production of other industrial chemicals. First of all the definition. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.

Whether you ride jet skis raft in white water race speed boats water ski or enjoy kayaking eva foam will easily become your best friend. Extreme sports enthusiasts should take note. Eva stands for ethylene vinyl acetate and it is the co polymer of ethylene and vinyl acetate. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool. Some of these derivatives include polyvinyl acetate polymers and ethylene vinyl acetate copolymers. Ethylene vinyl acetate eva is a copolymer of ethylene and vinyl acetate.

It also has good transparency and gloss and resistance at low temperature to stress cracking and uv radiation. Eva has a slight characteristic odour of vinegar acetic acid and competes with rubber products as well as with certain polymers in many electrical applications. The vinyl acetate content determines the degree of elasticity. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.

It is produced under high temperature and high pressure. 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. The interaction between vinyl acetate and ethylene monomers provides vae dispersions with an outstanding range of technical performance benefits along with environmental advantages at an attractive cost in use ratio. Vinyl acetate also known as vinyl acetate monomer or vam has a chemical formula of c4h4o2.

As the va content increases crystallinity decreases until at 50 the eva is. It is an extremely elastic and transparent material. Eva foam is the acronym for the closed cell ethylene vinyl acetate copolymer foam used as an effective substitute for a variety of materials used in production. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material.
