EVA EVA sheet extrusion machine is a plastic material of ethylene (E), and vinyl acetate (VA) of the composition. These two chemicals in line with the proportion of adjustable so different application needs, the higher the vinyl acetate (VA content) content, its transparency, softness and toughness will be relatively increased. Ethylene / vinyl acetate copolymer (EVA) ethylene - vinyl acetate copolymer (also referred to as ethylene - vinyl acetate copolymer A) is prepared from ethylene (E) and vinyl acetate (VA) copolymer, English called; Ethylene Viny Acetate, referred to as EVA, or E / VAC. polymerization process (for plastics) high-pressure bulk, solution polymerization (PVC processing aids). Emulsion (binder), suspension polymerization. Vinyl acetate (VA) content higher than 30% by emulsion, vinyl acetate content of low to high pressure bulk polymerization. EVA is very versatile. In general, vinyl acetate content EVA at 5% or less, and its main product is a thin film, wire and cable LDPE modifiers, adhesives and the like; vinyl acetate content of 5% -10% of the EVA product elastic membrane, etc; vinyl acetate content of 20% -28% of EVA, is mainly used for hot-melt adhesives and coating products; vinyl acetate in 5% -45%, the main products for film (including agricultural film) and sheet, injection molding, molded products , foam products, hot melt adhesives. It is widely used in foam shoes, functional films, packaging, molding, hot melt adhesives, wire and cable and toys and other fields. [1] an ethylene - vinyl acetate copolymer, referred to as EVA. Usually vinyl acetate (VA) content of 5% -40%, compared with polyethylene (PE), EVA molecular chain due to the introduction of vinyl acetate monomer, thus reducing the high crystallinity, improved toughness, impact resistance filler compatibility and heat sealing properties, it is widely used foam shoes, functional films, packaging, molding, hot melt adhesives, wire and cable and toys and other fields.
