Hot melt adhesive is the name of any polymer-based glue applied in a molten state. The application of adhesives is usually carried out through industrial glue guns, which work by triggering actions or finger pressure. Due to its versatility, hot melt adhesives are used in various environments, including packaging, binding, carton manufacturing, graphic arts, tapes and labels, product assembly, and the automotive industry.
Hot melt adhesive has become so popular that it has surpassed solvent-based adhesives. Solvent-based adhesives are mixtures of various components dissolved in solvents. When the solvent evaporates, the material will stick together. Polymer-based hot melt adhesives have solved many problems of solvent-based adhesives.
Compared with solvent-based adhesives, hot melt adhesives are faster, less costly, have stronger adhesion, and produce less volatile organic compounds.
Due to its chemical properties, hot melt adhesives can take various forms. This includes glue sticks, pellets, bags, cakes, drums, bricks, slats and pillows. Hot melt adhesives can also be applied in various ways, including through nozzles, extrusion, meltblown, spiral spraying, screen printing and slot die coating. Hot melt adhesive dispensing equipment can take the form of melt adhesive containers, vacuum conveyors, roller or bucket unloaders and pre-melt machines.

Hot melt adhesive is a type of plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Hot melt adhesive is melted by heating. The molten adhesive turns into a liquid and is then […]
Direct answer:Hot melt adhesive pelletsThe residual glue cannot be washed with water or ordinary alcohol. Commonly used are specialized hot melt adhesive cleaning agents (glue cleaning agents), high flash point white oil/mineral oil, and citrus terpene cleaning agents used in small quantities. The principle is to ‘soften with oil while hot, mechanically remove after cooling’, […]
