Ethylene Vinyl Acetate Uses

Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.

Ethylene vinyl acetate uses.

Eva shows good barrier and stretch properties. It shows good chemical resistance. Ethylene vinyl acetate offers good low temperature flexibility. Global ethylene vinyl acetate market to reach 9.

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. Ethylene vinyl acetate copolymer does not have an acid odor if it is not thermally degraded. 8 billion by 2027. 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.

Vinyl acetate is the acetate ester of vinyl alcohol. Amid the covid 19 crisis the global market for ethylene vinyl acetate estimated at us 8. On the basis of end use industry. Ethylene vinyl acetate properties ethylene vinyl acetate is a flexible and transparent thermoplastic.

Eva is used in several applications thanks to the varied properties it possesses. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. 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.

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. Each end use industry is further described in detail in the report with value and volume forecasts till 2020. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. 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.

B 1 ethylene vinyl acetate copolymers with or without the optional substances described in paragraph a of this section when extracted with the solvent or solvents characterizing the type of food and under conditions of time and temperature characterizing the conditions of their intended use as determined from tables 1 and 2 of 176 170 c. Use of dicumyl peroxide. This product should not be confused with the ethylene vinyl acetate eva copolymers. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
