What is pressure sensitive adhesive?

Pressure sensitive adhesive is a kind of adhesive which is sensitive to pressure.Mainly used for the preparation of pressure sensitive tape.The peeling force of general pressure sensitive adhesives (the peeling force shown by the adhesive tape and the surface to be stuck under pressure)The cohesive force (the force between the molecules of a pressure-sensitive adhesive) of an adhesive.Adhesive base force (adhesion between the adhesive and the substrate).This pressure sensitive adhesive in the use of the process will not have degumming and other phenomena.

The chemical characteristics and properties of pressure sensitive adhesives are mainly reflected in the following nine aspects:

1. Adhesion performance of pressure sensitive adhesive.
2. Wetting property of pressure sensitive adhesive.
3. Anti-peel performance of pressure sensitive adhesive.
4. Initial adhesion and retention of viscosity of pressure sensitive adhesive.
5. Creep shear resistance of pressure sensitive adhesive,
6. Temperature resistance of pressure sensitive adhesive.
7. Flame retardancy of pressure sensitive adhesive.
8. pressure sensitive adhesive anti-aging, anti-oxidation.
9. Corrosion resistance of pressure sensitive adhesive.

The properties of the pressure sensitive adhesive are greatly affected by the composition of the adhesive. For example, the rubber type of pressure sensitive adhesive based on natural rubber has low curing temperature, good viscosity and good temperature resistance, but its oxygen resistance and aging resistance are poor.

Silicone pressure-sensitive adhesives made of silicone rubber and silicone resin have strong peel resistance, but with the same type of pressure-sensitive adhesives mentioned above, they still have poor aging resistance.
