Ethylene Vinyl Acetate Uses

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

Ethylene vinyl acetate uses.

Eva is used in several applications thanks to the varied properties it possesses. Eva shows good barrier and stretch properties. Amid the covid 19 crisis the global market for ethylene vinyl acetate estimated at us 8. 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.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. On the basis of end use industry. This product should not be confused with the ethylene vinyl acetate eva copolymers. It shows good chemical resistance.

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. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Vinyl acetate is the acetate ester of vinyl alcohol. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.

Use of dicumyl peroxide. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. 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. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

Ethylene vinyl acetate offers good low temperature flexibility. Vinyl acetate ethylene vae emulsions are based on the copolymerization of vinyl acetate and ethylene in which the vinyl acetate content can range between 60 and 95 percent and the ethylene content ranges between 5 and 40 percent of the total formulation. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. 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.

8 billion by 2027. The ethylene vinyl acetate market is segmented on the basis of end use industry that include footwear foams packaging agriculture pharmaceutical photovoltaic panels and others. 4 billion in the year 2020 is. Ethylene vinyl acetate properties ethylene vinyl acetate is a flexible and transparent thermoplastic.
