About me: Hot melt adhesives exist in solid form and are
classified by different types of raw materials.
Polyurethane (Polyurethane Hot Melt Adhesive) is a
reactive type of hot melt adhesive for the base
material. After cooling, there will be a chemical
cross-linking reaction. Rubber-based
pressure-sensitive hot melt adhesives are mainly
used in packaging, labels ,metal back stickers and
so on.
