Definition of PUR Hot Melt Glue Laminating Machine: PUR (Polyurethane Reactive) is referred to as moisture-curing reactive polyurethane hot melt glue, hence the PUR hot melt glue laminating machine is also known as a moisture-curing reactive polyurethane hot melt laminating machine or PUR hot melt glue coating laminating machine.
A PUR hot melt glue laminating machine is a type of polymer equipment that utilizes a solvent-free, water-free, and 100% solid melt characteristic. It remains solid at room temperature but can melt once heated to a certain degree. Its working principle involves applying genuine hot melt glue onto a substrate, forming a liquid glue with flowability and viscosity, and then adhering another substrate onto the coated substrate. The bonding strength formed after the curing of PUR hot melt glue is high, capable of firmly bonding different types of materials.
