Compressed EVA mold is formed after the EVA hot melt adhesive material through the processing stage, EVA hot melt adhesive is the main component of ethylene and vinyl acetate under high pressure copolymerization resin as the basic resin, which determines the basic performance of hot melt adhesive. Together with the tackifier to improve the bond strength, glue viscosity and solidification rate regulator and a small amount of antioxidants to slow down the hot melt adhesive aging rate.
Hot melt adhesive is mainly used for book binding glue binding line, glue gutter in the gutter will be preheated hot glue, brushing to the back of the book after milling back to fight the hair.
EVA hot melt adhesive is a kind of solid meltable polymer no water and without the solvent. Hot melt at room temperature is solid, after being heated to a certain temperature it begins to melt, become the liquid with adhesive. Therefore, the EVA mould is formed, There are many kinds of hot-melt adhesives, the hot-melt glue be used for books and periodicals is polyethylene vinyl acetate.
