Vinyl acetate are abbreviated as eva high ethylene and low vinyl acetate content or vae high vinyl acetate and low ethylene content.
Is ethylene vinyl acetate biodegradable.
Added during the manufacturing process ecopure enhances the biodegradability of eva plastics and shortens the time plastics that have been disposed of.
Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.
Although the synthetic polymer is a useful material for the athletic shoe industry it has become an environmental concern because of its poor biodegradability.
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 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.
The properties are largely dependent on the molecular weight and the vinyl acetate content.
There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.
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.
