You can almost find EVA foam material everywhere! They are usually provided by EVA foam suppliers as EVA foam sheets, EVA foam rolls, EVA foam puzzle mats, EVA foam tapes and so on. But do you really know this foam material? Here we are showing you the way to know EVA foam materials better. Just simply follow us as below! You will get to know what the EVA foam is, how this foam material is manufactured and fabricated by foam manufacturers. This can definitely guide you when you want to buy EVA foam sheets.
Definition of EVA foam material
EVA (Ethylene-vinyl acetate) foam is made from blended copolymers of ethylene and vinyl acetate. In one sheet of EVA foam, The weight percentage of vinyl acetate usually ranges from 10 to 40%. Polyethylene material is another important element for EVA foaming production. The variation amount of foaming additives and catalysts in the molding process of EVA foam can affect its density, hardness, color, resilience and so on. EVA foam materials are of closed cell foam structure. They have lots of excellent performances including good water & moisture resistance, excellent cushioning & shock absorption, strong heat insulation and long term durability etc.. They are quite frequently used by various industries so that we can find out it in many places and products, such as shoe insole, soft foam mats, foam packaging, yoga block, swimming kickboard, floor underlay, custom EVA foam components and so on. Look: Here is how EVA foam sheets are manufactured. After the below 4 production processes, we will see a full sheet of EVA foam materials.
