EVA molding material is composed of ethylene-vinyl acetate copolymer, and it is made by copolymerization of ethylene and vinyl acetate, and its polymerization method is high-pressure bulk polymerization, which has very good performance and can be used in many industries. , Play a role in usage.
Characteristics and uses of EVA:
EVA particles can be produced into various types of EVA sheets, and then the sheets are processed in various ways. For example, punching can be used as packaging lining, and hot pressing can be made into shoe soles.
Biodegradable: Will not harm the environment when discarded or burned. EVA materials can be used in electronics, hardware, and toy industries.
Similar in price to PVX: EVA is more expensive than toxic PVC, but cheaper than phthalate-free PVC.
Does not contain phthalates: suitable for children's toys and will not produce plasticizer release hazards. High transparency, softness and toughness. The scope of application is very wide, super low temperature resistance (-70℃). Suitable for freezing environment. Resistant to water, salt and other substances, it can remain stable in most cases.
High heat adhesion: It can be firmly attached to nylon, polyester, canvas and other cloths.
Low bonding temperature: can speed up the production speed.
Lighter weight: EVA has a density of 0.91 to 0.93, while PVC has a density of 1.32. Silk screen and offset printing. It can be used for more fancy products, but EVA ink must be used.
