NEXT-LEVEL SILICONE ELASTOMERS
Upon becoming commercially viable in the 1940s, silicones have developed into a versatile class of polymers that form the basis of many products spanning a wide variety of consumer and industrial applications. Te inherent properties of this class of polymer enable a design space where viscosity, rheology and cure profile (if applicable) can be tailored to suit processing, and hardness along with elements of physical strength such as tensile, tear, and elongation can be
adjusted to enable longevity in the end-use application. Tough inherently insulative, silicones can be formulated into thermally and/or electrically conductive compositions allowing them to serve as a key material in technologically demanding applications. Te ability of silicone to offer protection from the environment or relatively harsh operating conditions is enabled, and sets them apart from other chemistries, by their inherent chemical stability and wide
