  • What Are the Dangers of Ethylene Vinyl Acetate? | …

    Ethylene vinyl acetate is a type of plastic — a polymer with a wide variety of uses, both residential and industrial. Ethylene vinyl acetate is not hazardous by ingestion, unless you eat an object made of EVA that's big enough to cause choking or other problems — in which case it would pose the same hazards as any other plastic object. At very high temperatures it can burn, although it ...
