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.

What is ethylene vinyl acetate used for. Vinyl acetate is used to make other industrial chemicals. 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. 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 is a type of plastic a polymer with a wide variety of uses both residential and industrial.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. 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. Use of dicumyl peroxide.

These chemicals are used mainly to make glues for the packaging and building industries. 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. 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.

They are also used to make paints textiles and paper. 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.
