Silicone - What is silicone?
A synthetic polymer made of alternating silicon and oxygen atoms, along with other elements such as carbon and hydrogen. Silicone can be produced in a variety of forms, each of which is manufactured with a key set of properties to suit the intended application. Silicones have exceptionally high thermal stability (their properties remain unchanged even at extreme temperatures), can repel water or absorb it, can act as electrical conductors or insulators, are flexible and durable, can be used to promote adhesion or lubrication, and are chemically resistant.
In labelling, silicone is the standard release agent used in pressure sensitive constructions to facilitate the removal of a label from its backing sheet. It is also used in some adhesives due to its resistance to heat, light, moisture, and various chemicals, and is also used as an additive in printing inks to improve flow.Go Back to Glossary
