EVA is made from ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer) by copolymerization of ethylene (E) and vinyl acetate (VA). The English name is: Ethylene Vinyl Acetate, referred to as EVA, E \/VAC. The polymerization method uses high-pressure bulk polymerization (for plastics), solution polymerization (PVC processing aid), emulsion polymerization (adhesive), suspension polymerization. Emulsion polymerization, acetic acid if the content of vinyl acetate (VA) is higher than 30 percent If the ethylene content is low, use high-pressure bulk polymerization.
Features and uses of EVA:
EVA particles can be produced into variousEVA sheet, and then the board is processed in various ways, such as punching, it can be used as a packaging lining, and hot pressing can be made into a shoe sole. Shenzhen Yidebao foams in this way and then processes and supplies them to other customers.biodegradable,It will not cause harm to the environment when discarded or burned. EVA materials can be used in electronics, metals, and toys.andThe price of PVC is similar: the price of EVA is more expensive than toxic PVC, but it is cheaper than PVC without phthalates.lighter weight;The density of EVA is between 0.91 and 0.93, while that of PVC is 1.32.no odor,EVA does not contain ammonia or other organic odors.
Does not contain heavy metals and complies with relevant international toy regulations (EN-71 Part 3 and ASTM-F963).Phthalates Free: Suitable for children's toys and will not cause the risk of plasticizer release.High transparency, softness and toughness: The scope of application is very wide.Super low temperature resistance(-70C): Suitable for icing environment.Resistant to water, salt and other substances: It can remain stable in the application of large portions.High thermal paste: Can be firmly attached to nylon, polyester, canvas and other fabrics.low bonding temperature: It can speed up the production speed.Screen printing and offset printing available: It can be used for more fancy products (but EVA ink must be used).
