Hot melt pressure sensitive adhesive ( hmpsa ) is a special type of hot melt adhesive that turns into a liquid state when heated and forms a viscous solid after cooling. It is pressure sensitive at room temperature. Pressure sensitive adhesives are divided into solvent type, emulsion type, hot melt type, etc. Hot melt pressure sensitive adhesive is the third generation of pressure sensitive adhesive products after solvent-based and emulsion-based pressure sensitive adhesives. Compared with the first two, hot melt pressure sensitive adhesive is more conducive to environmental protection and safe production. The biggest advantages of hot melt pressure sensitive adhesive are that it does not contain organic solvents, has low pollution, fast coating speed, high degree of automation, and low production cost. Hot melt pressure sensitive adhesive can be widely used in the automotive industry, electronics industry, packaging, medical and health care, wood processing, double-sided tape, label wallpaper, etc.
Features and Advantages of hmpsa
1) Good stickiness: Hot melt pressure sensitive adhesive has good stickiness at room temperature and can quickly adhere to many different surfaces, such as paper, plastic, metal, cloth, etc., without additional pressure.
2) Adhesion Reversible: Can be easily peeled off without leaving residue or damaging the surface.
3) Fast Adhesion:The adhesion of hot melt pressure sensitive adhesives occurs very quickly, and the adhesion effect is almost immediately visible upon contact with the surface.
4) Environmentally Friendly: Most hot melt pressure sensitive adhesives have lower emissions of volatile organic compounds (VOCs), making them more environmentally competitive.
