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.

Chemsrc provides vinyl acetate cas 108 05 4 msds density melting point boiling point structure formula molecular weight etc. 1 201 767 0414 fax. At low to moderate doses it produces irritation at the point of contact. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

At 50 c the solubility of vinyl acetate in water is 0 1 wt more than at 20 c but the solubility of water in vinyl acetate doubles to about 2 wt. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Melting point density additive chemical composition melt index hardness. 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 va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe. Vinyl acetate is the acetate ester of vinyl alcohol. Robles in encyclopedia of toxicology third edition 2014. As the va content increases crystallinity decreases until at 50 the eva is.
