Biodegradable ethylene vinyl acetate eva plastic is the copolymer of ethylene and vinyl acetate polymers.
It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
The monomer vinyl acetate was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury i salt but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene.
Flexible eva ethylene vinyl acetate is the copolymer of ethylene and vinyl acetate.
Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.
While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber.
There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.
