Electronics and electrical industry is one of the earliest and most demanding fields of silicone rubber as an insulating material. Silicone rubber is mainly used in TV anode cover, high-voltage protective cover, high-voltage lead-out wire, refrigerator defroster wire, power or signal transmission wire and cable, etc. Insulators made of silicone rubber will be widely used in power transmission lines instead of ceramic products, especially ultra-high voltage lines. Conductive silicone rubber is used for electrical contacts and liquid crystal display contacts of electronic computers and telephones. Wires and cables made of flame-retardant and radiation-resistant silicone rubber are widely used in nuclear power stations. Silicone rubber heating sheet and heating belt are used to control the working temperature of a variety of precision instruments and oil pipelines, and are used as heating blankets for physiotherapy thermal applicators in the medical field. Room temperature vulcanized silicone rubber can be used as a potting material for waterproof, moisture-proof and shock-proof.

Silicone rubber has been widely used in pump seals of dishwashers and washing machines due to its heat-resistant washing liquid performance. Silicone rubber is ideal for use as a gasket on appliances such as coffee pots, electric fryers, and steam irons. The earphones and head pads of the stereo headphones are changed to silicone rubber, which can eliminate external noise and is soft and comfortable.
