Ethylene Vinyl Acetate Structure

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.

Ethylene vinyl acetate structure.

Vinyl acetate as a polymer constituent in imported polymers. It shows good chemical resistance. Eva shows good barrier and stretch properties. Ethylene vinyl acetate copolymer emulsion.

Chemsrc provides ethylene vinyl acetate copolymer cas 24937 78 8 msds density melting point boiling point structure formula molecular weight etc. Ethylene vinyl acetate offers good low temperature flexibility. Ethylene vinyl acetate properties ethylene vinyl acetate is a flexible and transparent thermoplastic. The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Vinyl acetate c4h6o2 cid 7904 structure chemical names physical and chemical properties classification patents literature biological activities safety. Emblem in packaging technology 2012. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. 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.
