Short for pressure sensitive adhesive. It is a pressure sensitive adhesive. Mainly used for preparing pressure-sensitive adhesive tapes. Peeling force of general pressure-sensitive adhesive (peeling force after pressure bonding between adhesive tape and adhered surface)
Pressure sensitive adhesive can be divided into rubber type and resin type according to the main resin composition. Rubber types can be divided into natural rubber and synthetic rubber; The main resin types are acrylic acid, silicone and polyurethane.
Rubber-based pressure-sensitive adhesive is made of rubber as the main component and other auxiliary components, such as tackifying resin, plasticizer, filler, viscosity regulator, vulcanizing agent, antioxidant and solvent.
Besides the main resin, resin-based pressure-sensitive adhesive also needs additives such as defoamer, leveling agent and wetting agent.
In addition to the above classification methods, pressure-sensitive adhesives can also be divided into water-based and solvent-based pressure-sensitive adhesives according to different dispersion media; It can also be divided into packaging, protection, insulation, warning, labels, stationery and other products according to different uses.
Polypropylene sealing, textured paper and PVc electrical tape are the most common products in the market.
