Is Ethylene Vinyl Acetate Toxic

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

Is ethylene vinyl acetate toxic.

It s considered to be a safe alternative to pvc. It readily evaporates into air and dissolves easily in water. 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. It acts as a buffer a chemical that stabilizes the ph of a solution and also finds use in the tanning textile and petrochemical industries among others.

Eva looks and feels an awful lot like pvc so is it made with the same toxic chemicals. So while little is known about ethylene vinyl acetate toxicity from the evidence available it does look like peva is a less harmful material than pvc.
