The composition structure of pressure sensitive tape

Under normal circumstances, the composition of single-sided tape structure is: the release of the substrate, adhesive. The following image:

Categories of adhesives and their respective properties

The main adhesives are acrylic rubber, natural rubber, synthetic rubber, silicone and so on. For different application requirements, coating on the established release substrate.

For the above adhesive characteristics comparison:

Acrylic adhesive

Advantage:

Strong resistance to aging

Strong weather resistance

Strong temperature resistance

It usually has strong resistance to shear force at high temperature

Good adhesion to polar surfaces

Disadvantage

The initial peeling strength is low

The adhesion to non-polar surfaces is poor

High cost

Natural rubber

Advantage

The initial peel strength is high

It has strong resistance to shear force at high temperature

There are adhesive forces on all kinds of surfaces

Disadvantage

Poor aging resistance

Poor solvent resistance

Higher cost

Synthetic rubber

Advantage

There are adhesive forces for various surfaces, and non-polar surfaces are relatively better

The initial peel strength is high

Low cost

Disadvantage

High temperature resistance is very poor

Poor aging resistance

Poor weather resistance
