Silicone rubber materials and some plastic films have chemically inert and non-porous surfaces, which equates to low surface energy. This means they have a weak molecular bonding force making it difficult to create a bond with many pressure sensitive adhesives.

Silicone Rubber, a "Low Surface Energy" Elastomer - What Does This Mean?
Silicone is a high-performance elastomer with the ability to withstand extreme temperatures, both high and low. It also naturally repels, which makes it an excellent choice for a water seal or a moisture barrier. However, this also makes silicone tricky to bond to other surfaces.

The use of pressure sensitive adhesive tape is growing rapidly in manufacturing in practically all industries. This means more and more design engineers are in the process of selecting a pressure sensitive adhesive for their application. An imperative part of the adhesive selection process is to determine the surface energy of the two substrates that are being bonded.
