Eva Ethylene Vinyl Acetate

Biodegradable ethylene vinyl acetate eva plastic is the copolymer of ethylene and vinyl acetate polymers.

Eva ethylene vinyl acetate.

Eva mats will have a glossy appearance and are resistant to uv radiation and cracking. Eva is flexible has good clarity and is resistant to ultraviolet radiation. Eva is the copolymer of ethylene and vinyl acetate. The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Ethylene vinyl acetate a k a. Ethylene vinyl acetate copolymer resins sealing the deal our elvax ethylene vinyl acetate eva copolymer resins offer a variety of solutions for your sealants in meat and dairy packaging structures footwear wire and cable insulation as well as photovoltaic encapsulants and sheets.

Eva is used in several applications thanks to the varied properties it possesses. 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. Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility. Ethylene vinyl acetate offers good low temperature flexibility.

Eva foam is also waterproof. Added during the manufacturing process ecopure enhances the biodegradability of eva plastics and shortens the time plastics that have been disposed of. Emblem in packaging technology 2012. Ethylene vinyl acetate eva is a copolymer that is manufactured from ethylene and vinyl acetate monomer vam.

Vinyl acetate increases gas permeability impact strength crystallinity coefficient of friction and optical qualities. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. It shows good chemical resistance. As the va content increases crystallinity decreases until at 50 the eva is.

While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber. About ethylene vinyl acetate. The main advantages of eva is that it has good toughness flexibility clarity and gloss the ability to withstand low temperatures and good tear resistance. Eva shows good barrier and stretch properties.

Eva properties vary depending on the comonomers contents. Vinyl acetate ethylene vae emulsions are based on the copolymerization of vinyl acetate and ethylene in which the vinyl acetate content can range between 60 and 95 percent and the ethylene content ranges between 5 and 40 percent of the total formulation.
