Is Ethylene Vinyl Acetate Biodegradable

Ethylene vinyl acetate eva copolymers are random linear copolymers produced by the copolymerization of ethylene and vinyl acetate va either in a high temperature and high pressure free radical process or for high vinyl acetate materials in emulsion. 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 is a type of plastic a polymer with a wide variety of uses both residential and industrial.

Eva is a polyolefin copolymer of ethylene and vinyl acetate that provides durability and flexibility making it the most commonly used material found in athletic shoe midsoles.

Is ethylene vinyl acetate biodegradable.

Vinyl acetate are abbreviated as eva high ethylene and low vinyl acetate content or vae high vinyl acetate and low ethylene content. Are not biodegradable by pcl degrading microorganisms. Eva is flexible has good clarity and is resistant to ultraviolet radiation. Biodegradable ethylene vinyl acetate eva plastic is the copolymer of ethylene and vinyl acetate polymers.

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. The properties are largely dependent on the molecular weight and the vinyl acetate content. Although the synthetic polymer is a useful material for the athletic shoe industry it has become an environmental concern because of its poor biodegradability. Added during the manufacturing process ecopure enhances the biodegradability of eva plastics and shortens the time plastics that have been disposed of.

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.
