What Is Ethylene Vinyl Acetate Used For

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.

What is ethylene vinyl acetate used for.

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. These chemicals are used mainly to make glues for the packaging and building industries. 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. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.

Ethylene vinyl alcohol use is on the rise as it has widespread uses as a effective non toxic gas barrier. It is a plastic made by combining ethylene and vinyl acetate to create rubber like properties which can be used for shoe soles. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. They are also used to make paints textiles and paper.

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. It is a polymer that approaches elastomeric materials in softness and flexibility yet can be processed like other thermoplastics. 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. Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch. Vinyl acetate is used to make other industrial chemicals. Use of dicumyl peroxide. 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. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.

Vam is also used to make polyvinyl butyral pvb which is used in laminated safety glass for cars and buildings. That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility.
