Pressure sensitive adhesives have varying degrees of peel strength, and even different varieties of peel strength. When choosing a PSA for your application, you will want to consider the different types of peel strength and determine which are the most important to your application’s proper function.
Peel Strength – The strength of an adhesive joining two sheets of material. The strength is measured by the force required to peel apart those two sheets.
Tensile Strength – The strength of an adhesive relative to the forces that are perpendicular to the joint plane.
Shear Strength – The strength of an adhesive relative to the forces that are parallel to the joint plane. Think of using an adhesive to hang a very heavy picture on the wall. A high level of shear strength would be important.
