Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.
As the va content increases crystallinity decreases until at 50 the eva is.
It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
Articles of ethylene vinyl acetate copolymer are included as well.
Vinyl acetate is the acetate ester of vinyl alcohol.
The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe.

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 eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.
Articles of vinyl acetate are included as well.
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.
