What Is Eva Material Made Of

Ethylene vinyl acetate also known as eva is an elastic polymer material that is similar to rubber.

What is eva material made of.

Ethylene vinyl acetate or eva material is an elasticized closed cell foam with rubber like softness and flexibility. What we do know is that this material is free from phthalates which are reasonably anticipated to be a human carcinogen so while little is known about ethylene vinyl acetate toxicity from the evidence available it does look like peva is a less harmful material than pvc. It is resistant to cracks and ultraviolet radiation. Eva mouthguard material is an elastomer polymer that has soft flexible and rubber like properties.

It s considered to be a safe alternative to pvc. That is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. However conventional mouthguards that are made from this material are too soft to absorb the entirety of the force of impact and some of the force will travel. Eva stands for ethylene vinyl acetate.

Eva mats will have a glossy appearance and are resistant to uv radiation and cracking. 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. Swimming kickboard is one of products made by eva foam materials. It is a plastic made by combining ethylene and vinyl acetate to create rubber like properties which can be used for shoe soles.

Its purpose is to cushion the force of impact before it travels to the teeth. It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool. Ethylene vinyl acetate is a plastic made by combining ethylene and vinyl acetate. The eva copolymer which has a medium proportion of va approximately 4 to 30 is referred to as thermoplastic ethylene vinyl acetate copolymer and is a thermoplastic elastomer material.

Eva foam puzzle mats are made of molded eva foam materials usually with anti slip texture finishing on surface. Eva can also be made into eva foam with the use of a plasticizer. Eva foam is also waterproof. Therefore they are quite suitable for marine market usage.

It is not vulcanized but has some of the properties of a rubber or of plasticized polyvinyl chloride particularly at the higher end of the range. On the other hand the eva foam materials can be made in low density with lightweight property. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. It s very soft and elastic and it can be made into a plastic that s like rubber yet extremely tough.
