Description: Ethylene - vinyl acetate copolymer (EVA) is made by the copolymerization of ethylene and vinyl acetate in different proportions. The E in the abbreviation EVA stands for ethylene component, and VA stands for vinyl acetate component. Its performance is closely related to the content of vinyl acetate (VA), which can be divided into three categories according to the content of VA: VA content in 5%-40% said EVA plastic, mainly used for polyethylene modification, manufacturing wires and cables, film and other molding products and mixtures; VA content in 40%-90% is called EVA rubber, mainly used for rubber, cable and automotive industry parts; VA content above 90% is called polyvinyl acetate emulsion, mainly used for adhesives, coatings, etc.

Performance: EVA has good impact resistance and stress cracking resistance, softness, high elasticity, puncture resistance and chemical stability, good electrical properties, good biocompatibility, and low density, and with filler, flame retardant has good compatibility. EVA as the VA content is different, from plastic, rubber, and then to the emulsion, has a wide application range, suitable for extrusion, injection molding, blow molding, coating, hot forming and processing a variety of ways, can be applied to the cable, sealers, medical treatment, insulation film, pipe, plate, building materials, electrical accessories, auto accessories and daily necessities and other products. EVA is a brief description in the long chain structure of polyethylene (PE) the introduction of vinyl acetate (VA), the VA content is one of the biggest factors affecting its performance, because the VA is polar group, along with the increase of the content of VA crystallinity decreased, and improves the flexibility, impact resistance and oil resistance, but the polarity of the corresponding increase, so and packing intermiscibility increase, Flame retardancy also increased slightly.
