1, Natural rubber pressure sensitive adhesive: Natural rubber type pressure sensitive adhesive is the earliest open, rubber pressure sensitive rubber content is the largest, the first is natural rubber, and adhesion resin, softener, antioxidant, curing agent, solvent. Because natural rubber has high bond strength, elasticity, and pressure sensitivity and creep resistance, excellent compatibility, so prepare pressure sensitizer and excellent wetting. Because of the presence of unsaturated double bonds in the structure of natural rubber macromolecules, there is a defect of poor aging resistance. Hot melt adhesive, hot melt adhesive machine, hot melt adhesive machine, spraying equipment, dispensing machine.


2, synthetic rubber and regenerative rubber type pressure sensitive adhesive: This pressure is butadiene rubber, polypolyethylene, butadiene rubber, butadiene rubber, neoprene rubber, rubber and other synthetic rubber alone or linked as the main body, with adhesion resin softeners, Antioxidants, mixed solvents.


3, thermoplastic elastomer pressure sensitizer: hot melt pressure sensitizer head is based on SIS, SBS's thermoplastic elastomer representative as the primary raw material, using adhesive resin, adding softeners, antioxidants, energy saving, and eliminating pollution. Worth pursuing.


4, C | enoic acid pressure-sensitive binder: C | enoic acid pressure-sensitive binder is a variety of units of the C | enate copolymer working together. It is usually not necessary to add adhesion resins, softeners, anti-aging agents and coordination agents with outstanding pressor sensitivity, excellent anti-aging properties, it is very agile to develop, and in the fall to replace natural rubber pressor.


5,Other resins, silicone pressure sensitizers: The relative molecular weight of silicone pressure sensitizers composed of a mixture of two organic resins and silicone rubber is different, and some appearances can be low and adhesion can be strong. It has outstanding heat resistance and aging resistance. However, the price is high and the use of other amine resins, such as polyurethane, polyester, Eva, PVC, can also be deployed with various pressure sensitizers. According to the shape classification of pressure sensitive glue, it can be divided into six categories: solvent type, emulsion type, hot melt type, reaction type, rolling type, and aqueous solution type.
