Etheyl Vinyl Acetate

The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

Etheyl vinyl acetate.

Ethyl acetate is used primarily as a solvent and diluent being favored because of its low cost low toxicity and agreeable odor. Vinyl acetate is the acetate ester of vinyl alcohol. It shows good chemical resistance. 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 flexible and transparent thermoplastic. Vinyl acetate c4h6o2 cid 7904 structure chemical names physical and chemical properties classification patents literature biological activities safety. 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.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

For example it is commonly used to clean circuit boards and in some nail varnish removers acetone is also used. Eva shows good barrier and stretch properties. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Product name cas number. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous.
