EVA Hot Melt Glue Sheet Physical Composition And Development Background
- Jun 19, 2017 -

    EVA is a plastic material consisting of ethylene (E) and vinyl acetate (VA). The higher the content of these two chemicals, the higher the content of vinyl acetate (VA content), the transparency, softness and toughness will be relatively improved. Ethylene / Vinyl Acetate Copolymer (EVA) Ethylene-Vinyl Acetate Copolymer (also known as ethylene-vinyl acetate copolymer) is made by copolymerization of ethylene (E) and vinyl acetate (VA), English name; Ethylene Viny Acetate, referred to as EVA, or E / VAC. Polymerization method with high-pressure bulk polymerization (plastic), solution polymerization (PVC processing aids). Emulsion polymerization (binder), suspension polymerization. Vinyl acetate (VA) content of more than 30% of the use of emulsion polymerization, low vinyl acetate content with high-pressure bulk polymerization.EVA Hot Melt Glue Sheet

   EVA is very versatile. Under normal circumstances, the vinyl acetate content of less than 5% of the EVA, the main products are thin film, wire and cable LDPE modifier, adhesive, etc .; vinyl acetate content of 5% -10% EVA products for the elastic film, etc .; vinyl acetate Content of 20% -28% of the EVA, mainly for hot melt adhesives and coating products; vinyl acetate in 5% -45%, the main products for the film (including agricultural film) and sheet, injection molding, molded products , Foam products, hot melt adhesives and so on. Is widely used in foam shoes, functional film, packaging mold, hot melt adhesives, wire and cable and toys and other fields.EVA Hot Melt Glue Sheet

   Hot melt adhesive is a thermoplastic resin or thermoplastic elastomer as the main component, adding plasticizers, tackifying resin, antioxidants, flame retardants and fillers and other components, the melt-mixing made of solvent-free solid sticky mixture. Because of its non-toxic, no environmental pollution, easy preparation and so on to become the direction of the development of the adhesive market, the world's annual production has been on the rise, the growth rate of the highest in all types of adhesives, more diversified varieties, The more extensive.EVA Hot Melt Glue Sheet

   Ethylene and vinyl acetate copolymer (EVA) hot melt adhesive preparation method is simple, widely used in mechanized packaging, furniture production, footwear, wireless binding, electronic components and daily necessities bonding, quickly become the most widely used hot melt adhesives, The largest one.EVA Hot Melt Glue Sheet
