Ethylene Vinyl Acetate Structure

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

Ethylene vinyl acetate structure.

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. 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. Product name property description. Ethylene vinyl acetate polymer.

As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. Poly ethylene co vinyl acetate 4 product results. The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe.

The eva copolymer which is based on a medium proportion of va approximately 4 to 30 is referred to as thermoplastic ethylene vinyl acetate copolymer and is a thermoplastic elastomer material.
