Ethylene Vinyl Acetate Copolymer Eva

Ethylene vinyl acetate eva copolymers are used in extrusion film processes for applications including packaging surface protection and greenhouse covers and in photovoltaic cell encapsulation.

Ethylene vinyl acetate copolymer eva. Biodegradable ethylene vinyl acetate eva plastic is the copolymer of ethylene and vinyl acetate polymers. In addition poly vinyl acetate ethylene vae copolymers possess enhanced toughness flexibility and serviceability. Ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate. Skin and eye burns from molten product.

Eva is flexible has good clarity and is resistant to ultraviolet radiation. These material are used when a combination of softness toughness flexibility and polarity are needed. Ethylene vinyl acetate eva copolymer safety data sheet international polymers company safety data sheet according to regulation ec no. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. They are the base polymer in many adhesive resin formulations and in. Most important symptoms and effects both acute and delayed. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below.

The material has low temperature toughness stress crack and uv radiation resistance. Both effects result in a lowering of the tg of the final copolymer. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. Added during the manufacturing process ecopure enhances the biodegradability of eva plastics and shortens the time plastics that have been disposed of.

Eva offers good bondability and adhesion to polar substrates in extrusion coating and multi layer film applications. Eva copolymers are used in molded caps and seals footwear and car interiors. Flexible eva ethylene vinyl acetate is the copolymer of ethylene and vinyl acetate. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

Eva has many attractive properties including low cost excellent. 1272 2008 regulation ec no 1907 2006 ethylene vinyl acetate copolymer rev 1 01 2013 page 3 4 2. On a weight basis ethylene is far more effective a fact that is reflected in the low tg of polyethylene homopolymer below 80 c. Eva based hot melts are able to fulfill various requirements in applications such as packaging bookbinding or label sticking.

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.
