What is hot melt adhesive?
Hot melt adhesive is a plastic adhesive. Hot melt adhesive is a type of glue, and the range of use of hot melt adhesive is also very wide, mainly for bonding after heating, and the bonding effect is very good. Poisonous and tasteless, it is an environmentally friendly chemical product. Since the product itself is solid, it is easy to package, transport and store, without solvent, pollution, and toxicity, and has the advantages of simple production process, high added value, high bonding strength, and fast speed. It is heated and melted to a certain temperature to form a flowable liquid with a certain viscosity. The melted hot melt adhesive is light brown or white, and the hot melt adhesive is composed of base resin, tackifier, viscosity modifier and antioxidant.
Application 1 of hot melt adhesive:
There are many types of hot melt adhesives with a wide range of uses. Typically, hot melt adhesives are applied by extrusion, rolling or spraying, and their high melt viscosity makes them ideal for porous and permeable substrates. Hot melt adhesives can bond a range of different substrates including: rubber, ceramic, metal, plastic, glass and wood.
Application 2 of hot melt adhesive:
Today, hot melt adhesives are used in a wide variety of applications across multiple industries. For hobby or craft projects, such as the assembly or repair of remote-controlled foam model airplanes, and artificial flower arrangements, hot melt sticks and hot glue guns are used in adhesive applications. For use in industrial processes, adhesives are supplied in larger sticks and glue guns with higher melting rates. In addition to hot melt glue sticks, hot melt adhesives are also available in other forms, such as granular or powdered hot melt blocks for bulk melt processors. Larger applications of hot melt adhesives have traditionally used pneumatic systems to supply the adhesive.
