The PUR hot melt glue machine is a revolutionary piece of equipment that has significantly impacted the adhesive industry. PUR , which stands for polyurethane reactive adhesive, is a type of adhesive that offers exceptional bonding strength and durability. The PUR hot melt glue machine is specifically designed to apply this adhesive with precision and efficiency. Now widely used in packaging, wood processing, automotive, textile , electromechanical, aerospace and other fields.
PUR adhesives contain polar and chemically active urethane groups (-NHCOO-) or isocyanate groups (-NCO) in their molecular structure, and are used with materials containing active hydrogen, such as wood, leather, fabrics, paper, ceramics and other porous materials. . It also has excellent adhesion to materials with smooth surfaces such as plastics, metals, glass, and rubber.
Due to the particularity of the PUR hot melt glue machine, PUR hot melt glue is also called moisture-curing reactive polyurethane hot-melt glue. It is also called moisture-hardening reactive polyurethane hot-melt glue, or PUR hot-melt glue for short. If it comes into contact with water vapor in the air during use, it will react and solidify. Therefore, it needs to be completely isolated from the air during melting and use with the PUR hot melt glue machine. It is specially designed for the coating of polyurethane hot melt glue.
The biggest difference between polyurethane hot melt glue machines and ordinary hot melt glue machines is that the entire hot melt glue coating process is completely isolated from the air. Ordinary hot melt glue machines melt the hot melt glue from bottom to top, while PUR hot melt glue machines melt the hot melt glue from top to bottom. The PUR hot melt glue is melted under the pressure, so one of the core components of the PUR hot melt glue machine is the hot melt glue pressure plate heating element.
Furthermore, the PUR hot melt glue machine is designed with efficiency in mind. Its automated dispensing system and ergonomic design allow for seamless operation, reducing the time and effort required to apply PUR adhesive. This not only increases productivity but also minimizes waste, as the machine ensures precise application without excess adhesive.
In addition to its technical capabilities, the PUR hot melt glue machine is also valued for its environmental benefits. PUR adhesive is known for its low volatile organic compound (VOC) content and non-toxic nature, making it an eco-friendly choice for adhesive applications. The machine’s efficient adhesive application further reduces material waste, contributing to sustainable manufacturing practices.
In conclusion, the PUR hot melt glue machine represents a significant advancement in adhesive technology. Its precision, versatility, efficiency, and environmental benefits make it a valuable asset for industries and craftspeople seeking high-performance adhesive solutions. As the demand for strong and sustainable bonding solutions continue to grow, the PUR hot melt glue machine has undoubtedly become an indispensable tool in the adhesive industry.
