3m pressure sensitive adhesive is a kind of material between viscous liquid and elastic solid.
When more softeners are added, the pressure-sensitive adhesive film shows the characteristics of viscous liquid, is easy to wet the surface of the adherend, and has good initial viscosity.
However, due to the decrease of modulus and viscosity, irreversible viscous deformation increases, cohesion decreases and viscosity retention decreases.
3m pressure sensitive adhesive is generally composed of polymer elastomer, such as sis, SBS, tackifier, plasticizer, filler and antioxidant.
Among them, the matrix of different brands has obvious influence on the mechanical properties of the system.
The hot-melt pressure-sensitive adhesive based on SIS is better than SBS, but in order to reduce the cost, the two can be mixed as the matrix.
3m pressure sensitive adhesive is mainly used for assembling furniture edge sealing, electronic industry, automobile interior sealing, lamp manufacturing and windshield assembly.
At the same time, it can also be used for non-woven sanitary napkins, diapers, diapers, insoles, disposable daily necessities, coating composite trademark paper and label double-sided tape.
