Eva Ethylene Vinyl Acetate Toxic

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Eva ethylene vinyl acetate toxic.

Eva looks and feels an awful lot like pvc so is it made with the same toxic chemicals. It s considered to be a safe alternative to pvc. Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility. Is eva foam toxic.

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. 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. When combined with heat pressure and other plastics eva becomes closed cell eva foam. Eva can also be made into eva foam with the use of a plasticizer.

Ethylene vinyl acetate is widely accepted as a safe alternative to other types of materials because it doesn t require the use of plasticizers to make it and it s very stable once manufactured. It has a sweet pleasant fruity smell but the odor may be sharp and irritating to some people. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. 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.

Vinyl acetate is the acetate ester of vinyl alcohol. Vinyl acetate is a clear colorless liquid. Our advice regarding products that contain peva at the moment is to use them with caution. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

It is always good practice to be aware of what your products are made of and what adverse affects these. If you aren t sure what a plasticizer is phthalates are an example you might be familiar with and i. Eva stands for ethylene vinyl acetate which is a soft and flexible plastic that s also very strong. It readily evaporates into air and dissolves easily in water.

Eva foam is also waterproof. While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber. Ethylene vinyl acetate is a plastic made by combining ethylene and vinyl acetate. 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.

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. Eva is often used as a safe alternative to pvc. It s also bpa free. Ethylene vinyl acetate eva is widely accepted as safe for use in teethers.
