Simply put, hot melt adhesive is a kind of adhesive product that is melted by heating and hardened by cooling, thus forming a bonding strength. Because it melts when heated, hot melt adhesives do not require solvents to wet the surface of the object to be adhered to, so hot melt adhesives are also an environmentally friendly adhesive.
Hot melt adhesive composition by the basic raw materials, tackifying resin, plasticizers, fillers, other additives, etc., which accounts for the largest proportion of the basic raw materials. The basic raw materials determine the basic properties of hot melt adhesive and the use of characteristics. Hot melt adhesive basic raw materials are divided into EVA, TPU, PA, PES, PO and other categories, the Chinese chemical name were called ethylene vinyl acetate **** polymer, thermoplastic polyurethane, polyamide, polyester, polyolefin.
Hot melt adhesive particles
Hot melt adhesive in accordance with the form, can be divided into hot melt adhesive particles, hot melt adhesive stick, hot melt adhesive block, hot melt adhesive powder, hot melt adhesive film, hot melt adhesive film, hot melt adhesive mesh, hot melt adhesive line and so on.
The application of hot melt adhesive is very wide, at present, there are many applications in the field of clothing, shoes, packaging, automobile industry, home building materials, decorative materials and so on.
