he pressure sensitive adhesive can be classified into two types according to the main resin component: a rubber type and a resin type. The rubber type can be further divided into natural rubber and synthetic rubber; the resin type mainly includes acrylic, silicone and polyurethane.
In addition to the main component of the rubber pressure sensitive adhesive, it is also added with other auxiliary components such as tackifying resin, plasticizer, filler, viscosity modifier, vulcanizing agent, anti-aging agent and solvent.
In addition to the main resin, the resin pressure sensitive adhesive needs to be added with an antifoaming agent, a leveling agent, a wetting agent and the like.
In addition to the above classification methods, pressure sensitive adhesives can be divided into water-based and solvent-based pressure-sensitive adhesives according to different dispersion media; and can be divided into packaging, protection, insulation, warning, labeling, stationery and other products according to different purposes.
