The Introduction Of EVA Hot-melt Adhesive
- Mar 02, 2017 -

EVA is a plastic item ethylene (e) and vinyl acetate (VA) formed. Both chemicals can be adjusted to meet different application needs, vinyl acetate (VA content) content, the higher its transparency, flexibility and toughness will improve. Ethylene vinyl acetate copolymer (EVA)

Ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer) is made of vinyl (e) and vinyl acetate (VA) copolymer produced, its English name; Ethylene Viny Acetate, also known as EVA or E/VAC. aggregate methods with high pressure polymerization (plastic), solution (PVC processing aid). Emulsion aggregation (bonding agent), the suspension polymerization. Vinyl acetate (VA) levels above 30% by emulsion polymerization and low content of vinyl acetate with high pressure polymerization. EVA uses is very wide. General situation Xia, acetic acid vinyl content in 5% following of EVA, its main products is film, and wire cable LDPE modified sex agent, and adhesive of,; acetic acid vinyl content in 5%-10% of EVA products for elastic film,; acetic acid vinyl content in 20%-28% of EVA, main for hot melt Adhesive and coating products; acetic acid vinyl in 5%-45%, main products for film (including agricultural film) and tablets material, injection, and die plastic products, sent bubble products, hot melt Adhesive,. Is widely used in foam shoes, functional films, packaging, mold, hot-melt Adhesive, wires and cables, toys, and other fields.
