Eva Rubber Ethylene Vinyl Acetate

That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility.

Eva rubber ethylene vinyl acetate.

Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility. They are both in the polyolefin family. 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 is a type of plastic a polymer with a wide variety of uses both residential and industrial.

The weight percent vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Ethylene vinyl acetate copolymer eva properties and applications. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.

It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. Eva foam is the acronym for the closed cell ethylene vinyl acetate copolymer foam used as an effective substitute for a variety of materials used in production. Ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate. It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool.

The higher the va content the more rubber like the eva resin is. Eva is a step up from straight polyethylene. Eva ethylene vinyl acetate has rubber like properties but tends to be softer than rubber which means lesser padding and more flexibility. While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber.

Eva foam is also waterproof. Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings. 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. Eva stands for ethylene vinyl acetate.

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. It is a plastic made by combining ethylene and vinyl acetate to create rubber like properties which can be used for shoe soles. Rubber on the other hand provides better traction and does not.
