Does the hot melt adhesive film contain such harmful substances as formaldehyde?
The main components of the hot melt adhesive film are high molecular polymers, that is, polyamide, polyurethane and other materials.
They have a high degree of polymerization, so they are not harmful to the human body. At the same time, the hot melt adhesive film wets
the surface of the adhered material by heating and melting, and it does not need a solvent to help wet the material.
Therefore, the hot melt adhesive film is an environmentally friendly adhesive that does not contain formaldehyde or solvents.
