                                            Features and working principle of PUR hot melt adhesive machine

Due to the particularity of the PUR hot-melt adhesive machine, PU hot-melt adhesive is also called moisture-curing reactive polyurethane hot-melt adhesive, also known as moisture-curing reactive polyurethane hot-melt adhesive, referred to as PUR hot-melt adhesive. When in use, it will react and solidify if it comes into contact with water vapor in the air. Therefore, it needs to be completely isolated from the air during melting and use with a PUR hot melt adhesive machine. The PUR hot melt adhesive machine is specially designed for the coating of polyurethane hot melt adhesives. .

The biggest difference between the polyurethane hot melt adhesive machine and the ordinary hot melt adhesive machine is that the whole hot melt adhesive coating process is completely isolated from the air. The ordinary hot melt adhesive machine melts the hot melt adhesive from the bottom to the top, and the PUR hot melt adhesive machine melts from the top to the top. The PUR hot melt adhesive is melted down, so one of the core components of the PUR hot melt adhesive machine is the heating element of the hot melt adhesive plate.
