What is EVA and what are its uses?

Ethylene vinyl acetate or EVA is a copolymer made of ethylene and vinyl acetate and is used in industrial coatings and laminates. Also, this copolymer has many uses in the film industry due to its high flexibility and transparency. EVA copolymer is composed of 10 to 15 mole percent vinyl acetate, which is attached to ethylene as a polar substituent. If a small percentage of vinyl acetate is used in the production of EVA, it can also be used in food packaging due to its non-toxicity.

EVA is a polymer that is similar to elastomer materials in terms of flexibility and softness, while it is similar to thermoplastic materials in terms of process ability. EVA can be a suitable alternative to PVC due to its high flexibility and the absence of the risk of plasticizers penetrating the surface.

This polymer has many applications in various industries due to its properties and characteristics such as low weight, colorlessness, mold ability, high transparency and lower price compared to natural rubber.
