Eva Rubber Ethylene Vinyl Acetate

Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility.

Eva rubber ethylene vinyl acetate.

They are both in the polyolefin family. It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool. Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. Eva stands for ethylene vinyl acetate.

Eva ethylene vinyl acetate has rubber like properties but tends to be softer than rubber which means lesser padding and more flexibility. Ethylene vinyl acetate eva is the copolymer of ethylene and vinyl acetate. The higher the va content the more rubber like the eva resin is. Rubber on the other hand provides better traction and does not.

It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. Eva foam is also waterproof. While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber. Eva mats will have a glossy appearance and are resistant to uv radiation and cracking.

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

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier. 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. Eva is a step up from straight polyethylene.

Both these materials have unique properties. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.
