Q:

What is EVA material?

A:

Ethylene vinyl acetate, also known as EVA, is an elastic polymer material that is similar to rubber. EVA usually contains no more than 40 percent vinyl acetate by weight, with the rest of the polymer being ethylene. It is resistant to cracks and ultraviolet radiation.

EVA is known to have an odor similar to vinegar, though the odor is not very strong. It is used in a variety of consumer products including soccer cleats, plastic wrap and foam stickers. In other products, EVA can be used as a substitute for cork.

EVA cannot be broken down by the human body, but it is largely inert and does not cause much of a reaction, if any, when implanted.
