For users who use the hot-melt adhesive coater, they may be familiar with it, but there are still many friends who are not familiar with it. There are many brief introductions about the hot-melt adhesive coater on the official website of Yonggao machinery. If you need, you can inquire by yourself. Today we mainly share the hot-melt adhesive density knowledge of the hot-melt adhesive coater.

The density of hot melt adhesive coating machine is generally 0.95-1.6g/cm3, and its density depends on the number of fillers (the more fillers, the higher the density). Because the hot-melt adhesive coater requires a certain coating area when working, the coating amount per unit length of non filler hot-melt adhesive with low density is less than that of filler hot-melt adhesive. It is possible that the usage of unfilled hot melt adhesive is less than that of filled hot melt adhesive to achieve the same edge sealing effect. In order to reduce the amount of gluing, the edge banding machine must have a good gluing system.
