Eva Ethylene Vinyl Acetate Toxic
Eva looks and feels an awful lot like pvc so is it made with the same toxic chemicals.
Eva ethylene vinyl acetate toxic. 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. 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. Eva mats will have a glossy appearance and are resistant to uv radiation and cracking. It readily evaporates into air and dissolves easily in water.
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. If you aren t sure what a plasticizer is phthalates are an example you might be familiar with and i. It s considered to be a safe alternative to pvc.
It has a sweet pleasant fruity smell but the odor may be sharp and irritating to some people. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility. It s also bpa free.
It s very soft and elastic and it can be made into a plastic that s like rubber yet extremely tough. Is eva foam toxic. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. 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.
Our advice regarding products that contain peva at the moment is to use them with caution. Eva stands for ethylene vinyl acetate which is a soft and flexible plastic that s also very strong. 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. Ethylene vinyl acetate eva is widely accepted as safe for use in teethers.
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. Vinyl acetate is a clear colorless liquid. While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber. Vinyl acetate is the acetate ester of vinyl alcohol.
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. Eva foam is also waterproof. It is always good practice to be aware of what your products are made of and what adverse affects these.
