Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Ethylene vinyl acetate structure.

Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. Product name property description. Ethylene vinyl acetate polymer. 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.

It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. Ethylene vinyl acetate copolymer emulsion. The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe.

It is not vulcanized but has some of the properties of a rubber or of plasticized polyvinyl chloride particularly at the higher end of the range.
