A letter about EVA/PVA online:
"Ed:
When did PVAs begin to be known as EVAs? I thought that EVA stood for the Ethylene Vinyl Acetate group of plastics which are normally solid at room temperatures and are often used in glue guns. I know that there has been some controversy about the "A" in PolyVinyl Acetate and PolyVinyl Alchohol.

> Elmer's Glue is a family menber of the PVA group but like all other families, all the members are different. This group of adhesives is now known as EVA.
> Elmer's is less flexible and doesn't age as well as other EVA's. I advise Elvace or if you wish a soluble EVA.
