HMPU (polyurethane) base material hot melt adhesive, it is a kind of hot melt adhesive with the best performance, and it is the guarantee of high quality sheet edge sealing. It is expensive and requires special usage.
The performance of furniture edge sealant
1. Viscosity of furniture edge sealant
The viscosity of furniture edge sealing glue does not directly reflect the performance of the glue. In general, the higher the viscosity of the furniture edge sealant, the better its initial tack strength, but the worse the coating performance. Low-viscosity hot melt adhesives have a smaller amount of glue and better wetting properties. Some hot melt adhesives with low viscosity and fast curing speed may also have high initial tack strength.
2. Density of furniture edge sealing glue
The density of furniture edge sealant is generally 0.95-1.6g/cm3, and its density depends on the amount of filler.
3. Softening point and use temperature of furniture edge sealing glue
The softening point is an indicator of the heat resistance of the furniture edge sealant. The higher the softening point, the less likely the furniture edge sealant will melt. At the same time, softening point is also an important aspect to measure the temperature resistance of panel furniture.
4. The opening time of the furniture Edge Banding Glue and the feeding speed of the edge banding machine
Furniture edge sealant is widely used in the market because of its solvent-free, water-resistant, and environmental-friendly features.
