The electronics and electrical industries are the earliest and most demanding areas for the use of silica gel as an insulating material. Silicone is mainly used for TV anode covers, high voltage protective covers, high voltage lead wires, refrigerator defroster wires, power or signal transmission wires and cables. Insulators made of silica gel are widely used in place of ceramics for transmission lines, especially ultra-high voltage lines. Conductive silica gel is used for electrical contact parts and liquid crystal display contact parts of electronic computers, telephones and the like. Wires and cables made of flame retardant and radiation resistant silicone are widely used in atomic power stations. Silicone heating sheets and heating belts are used to control the operating temperature of various precision instruments and oil pipelines, and are used as medical heating blankets for medical treatments. Room temperature curing silicone can be used as a potting material for waterproofing, moisture proof and shockproofing.

Silicone has been widely used in pump seals for dishwashers and washing machines due to its heat-resistant washing liquid properties. Silicone is ideal for use as a gasket on appliances such as coffee pots, electric fryers and steam irons. Stereo earphones and head pads are made of silicone, which eliminates external noise and is soft and comfortable.
