PUR hot melt adhesive (reactive polyurethane hot melt adhesive) is a high-performance adhesive. Its main component is isocyanate terminated polyurethane prepolymer, which endows PUR hot melt adhesive with adjustable adhesion and toughness, as well as excellent bonding strength, temperature resistance, chemical corrosion resistance, and aging resistance.
PUR hot melt adhesive changes from solid to liquid under heating conditions, making it easy to apply to the surface of the material to be bonded. After cooling, it quickly returns to solid state, completing the bonding process. Its curing process is unique, through the combined action of physical curing and chemical cross-linking reactions, producing polyurethane elastomers with high cohesion, thereby achieving strong adhesion to various materials.
PUR hot melt adhesive has a wide range of applications, including but not limited to automotive manufacturing, electronic assembly, packaging printing, woodworking furniture and other fields. In the automotive industry, it is often used to bond waterproof fabrics, seats, body shells and other components; In electronic assembly, it can be used for bonding precision components such as screens and backboards.
