What Is Ethylene Vinyl Acetate Used For

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.

What is ethylene vinyl acetate used for.

Use of dicumyl peroxide. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. 47 but elevated temperature and presence of some additives for example high amounts of clay cause the production of pungent acetic acid odor which is a product of thermal degradation of ethylene vinyl acetate copolymer. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. They are also used to make paints textiles and paper. It is a polymer that approaches elastomeric materials in softness and flexibility yet can be processed like other thermoplastics. Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch.

Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings. 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. Eva stands for ethylene vinyl acetate. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.

Vinyl acetate is the acetate ester of vinyl alcohol. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. Vinyl acetate is used to make other industrial chemicals. Ethylene vinyl acetate eva resin is also made from vam and is used in the manufacture of packaging film heavy duty bags extrusion coating wire and cable jacketing hot melt adhesives and cross linked foam.

Ethylene vinyl alcohol use is on the rise as it has widespread uses as a effective non toxic gas barrier. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. These chemicals are used mainly to make glues for the packaging and building industries. Ethylene vinyl acetate also known as eva is the copolymer of ethylene and vinyl acetate the weight percent vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

Vam is also used to make polyvinyl butyral pvb which is used in laminated safety glass for cars and buildings. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.
