Is Ethylene Vinyl Acetate Toxic

Potentially toxic to reproduction.

Is ethylene vinyl acetate toxic.

Eva can also be made into eva foam with the use of a plasticizer. Reaction mass of ethylene and vinyl acetate. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Vinyl acetate is a clear colorless liquid.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. As the va content increases crystallinity decreases until at 50 the eva is. It s very soft and elastic and it can be made into a plastic that s like rubber yet extremely tough. 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.

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 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. Comes from a harmonised c l classifying the substance as suspected toxic to reproduction repr. 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 is a type of plastic that does not require a plasticizer and is bpa free so it is considered to be a safer alternative material. Ethylene vinyl acetate eva is widely accepted as safe for use in teethers. 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. It readily evaporates into air and dissolves easily in water.

Eva looks and feels an awful lot like pvc so is it made with the same toxic chemicals. It has a sweet pleasant fruity smell but the odor may be sharp and irritating to some people. Comes from industry data where a majority of data submitters agree the substance is toxic to reproduction. Vinyl acetate is the acetate ester of vinyl alcohol.

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. Ethylene vinyl acetate is a plastic made by combining ethylene and vinyl acetate. You can easily smell vinyl acetate when it is in the air at levels around 0 5 ppm half a part of vinyl acetate in 1 million parts of air. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Sodium acetate is a ionic compound with the chemical formula c2h3nao2 commonly used in labs especially biochemistry labs 2 3. Our advice regarding products that contain peva at the moment is to use them with caution.
