Etheyl Vinyl Acetate

Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate.

Etheyl vinyl acetate.

The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe. Vinyl acetate c4h6o2 cid 7904 structure chemical names physical and chemical properties classification patents literature biological activities safety. For example it is commonly used to clean circuit boards and in some nail varnish removers acetone is also used. Ethylene vinyl acetate offers good low temperature flexibility.

Product name cas number. The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Ethylene vinyl acetate is a flexible and transparent thermoplastic. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

Ethyl acetate is used primarily as a solvent and diluent being favored because of its low cost low toxicity and agreeable odor. Eva shows good barrier and stretch properties. Coffee beans and tea leaves are decaffeinated with this solvent. 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.

Poly ethylene vinyl acetate 1 product result match criteria. Vinyl acetate is the acetate ester of vinyl alcohol. United states pharmacopeia usp reference standard. It shows good chemical resistance.

Poly 1 vinylpyrrolidone co vinyl acetate 1 product result. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous.
