What Is Ethylene Vinyl Acetate Used For

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

What is ethylene vinyl acetate used for.

Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch. 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. They are also used to make paints textiles and paper. 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.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. These chemicals are used mainly to make glues for the packaging and building industries. It is a polymer that approaches elastomeric materials in softness and flexibility yet can be processed like other thermoplastics. 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.

Vinyl acetate is used to make other industrial chemicals. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. Vam is also used to make polyvinyl butyral pvb which is used in laminated safety glass for cars and buildings. Vinyl acetate is the acetate ester of vinyl alcohol.

Use of dicumyl peroxide. 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.
