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.

Over the years, the use of pressure sensitive adhesive tape has grown rapidly in manufacturing and practically all other industries. This means a growing number of design engineers are learning about and sourcing pressure sensitive adhesives for their application. Adhesive selection is an involved process is to determine the surface energy of the two substrates that are being bonded.
