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 foam sheet.
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.
Products can include foam sheets expanded foam rubber mats sports equipment children s toys and more.
Polyethylene material is another important element for eva foaming production.

The result is a smooth fine cell sheet that is suitable for use in a wide variety of situations.
While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber.
It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool.
The variation amount of foaming additives and catalysts in the molding.
Eva foam is also waterproof.
The material has good low temperature toughness stress crack resistance hot and resistance to uv radiation.
Depending on the mixture and the way of manufacturing eva can be made a number of shapes and molds.
Eva foam is closed cell foam made from ethylene vinyl acetate eva and blended copolymers.
Eva foam is otherwise known as ethylene vinyl acetate foam.
In stock and custom made eva foam sheets continuous rolls flat buns and foam tapes with or without adhesive.
Used for bath or wheelchair seats covers knee pads headset or electronic cassette protectors swim boards fins shoes sandal soles toys and tricycle wheels.
Features include flexible self skinning reticulated and resistant to water uv heat abrasion shock and fire.
Eva ethylene vinyl acetate foam is made from blended copolymers of ethylene and vinyl acetate.
Eva foam is primarily used in industrial and commercial applications.
In one sheet of eva foam the weight percentage of vinyl acetate usually ranges from 10 to 40.
Impact and vibration absorption.
Custom manufacturer of injection molded ethylene vinyl acetate eva foam.
It has a high level of chemical cross linking.
Foam injection molding means that the hot liquid foam mixture of ethylene vinyl and acetate is sprayed into a mold.
Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility.
As eva is a closed cell foam it is particularly suited to gaskets or similar applications.
Several different types of eva are created where the vinyl acetate amount ranges from between 5 percent to 50 percent.
Benefits of eva foam include.
Eva mats will have a glossy appearance and are resistant to uv radiation and cracking.
