본문내용

Pressure Sensitive is a term commonly used to designate a distinct category of adhesives based on
elastomeric materials, such as Styrene Block Copolymers, which in dry form are permanently tacky at room or low temperature.

The polymer in a pressure sensitive adhesive is a viscoelastic material that is permanently as well as aggressively tacky and has enough cohesive strength and elasticity to be cleanly removed from a substrate surface. These polymers are typically linear polymers with a slight degree of cross-linking. The degree of crosslinking is one of the key features controlling the balance between cohesive and adhesive strength of the polymer. Functional groups to increase adhesive strength can also be placed onto the unsaturation sites.
