Rubber vs. Silicone vs. Acrylic Adhesives

Posted by Packaging Group on

What Is A Pressure Sensitive Adhesive (PSA)?

Pressure sensitive adhesive (PSA, self adhesive, self stick adhesive) is an adhesive tape that is permanently tacky and adhere spontaneously to a surface with only light pressure. Pressure Sensitive Adhesives do not require solvent, water, or heat to activate the adhesive. Rather, they are bonded by the initial force of application. PSA will adhere to a variety of diverse materials such as paper, glass, wood, plastic or metal, when applied to clean and dry surfaces with no more than finger or hand pressure. A PSA has a balance between adhesion and cohesion forces.

Advantages of Pressure Sensitive Adhesives:

  • Thinner and lighter materials

  • Bonds various substrates

  • Inherently tacky

  • Tailorable to the application

  • Can serve a variety of temperature ranges

  • Eliminates the need for surface refinishing

  • Eliminatesthe need for mechanical fasteners

  • Safe and easy to install or apply.

  • Cost effective to apply

Three Types Of Pressure Sensitive Adhesives:

Rubber - Rubber adhesives are based on natural or synthetic rubbers. Rubber adhesives are the most cost effective with quick stick characteristics. Rubber adhesives are not recommended for high temperature applications.

Acrylic - Acrylic adhesives are formulated with acrylic polymers. They generally possess resistance to environmental factors giving them better long-term aging. Acrylic adhesives tend to develop a stronger bond than rubber adhesives and can withstand higher temperatures.

Silicone: Silicone adhesives are formulated with silicone polymers and thus are the only adhesive that will bond well with silicone substrates. These adhesives are generally higher priced and possess a very low initial tack.
