Ethylene-vinyl acetate copolymer (EVA) is obtained by copolymerizing ethylene and vinyl acetate in different proportions. The E in the English abbreviation of EVA represents the ethylene component, and VA represents the vinyl acetate component. Its properties are similar to those of vinyl acetate (VA). The content is closely related, and can be divided into three categories according to the VA content: VA content between 5% Chemicalbook and 40% is called EVA plastic, which is mainly used for polyethylene modification, manufacturing wires and cables, films and other molded products and mixtures; VA content between 40% and 90% is called EVA rubber, which is mainly used in rubber, cables and automotive industry components; VA content above 90% is called polyvinyl acetate emulsion, which is mainly used in adhesives, coatings, etc.

Ethylene-vinyl acetate copolymer has good impact resistance and stress cracking resistance, softness, high elasticity, puncture resistance and chemical stability, good electrical properties, good biocompatibility, low density, and is compatible with fillers and flame retardant. The agent has good compatibility. EVA has a wide range of applications depending on the VA content, from plastic, to rubber, to latex. It is suitable for various processing methods such as extrusion, injection molding, blow molding, coating, thermoforming, etc. It can be applied to cables, Seals, medical, insulating films, pipes, plates, building materials, electrical accessories, auto parts and daily necessities and other products
