Etheyl Vinyl Acetate

Ethylene vinyl acetate offers good low temperature flexibility.

Etheyl vinyl acetate.

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. Ethyl acetate is used primarily as a solvent and diluent being favored because of its low cost low toxicity and agreeable odor. Ethylene vinyl acetate is a flexible and transparent thermoplastic. The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. It shows good chemical resistance. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

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. United states pharmacopeia usp reference standard. 2 1 2 methoxymethoxy ethyl vinyl 4 methyl 6 oxobicyclo 2 2 2 oct 2 yl acetate 1 product result match criteria. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous.

Product name cas number. For example it is commonly used to clean circuit boards and in some nail varnish removers acetone is also used.
