(2) Electronic and electrical industries
Electronic and electrical industry is the earliest use of silicone rubber as insulating materials, a large demand for a field. Silicone rubber is mainly used in TV anode cover, high voltage protective cover, high voltage lead wire, refrigerator defrost wire, power or signal transmission wire and cable. Insulators made of silicone rubber will replace ceramic products widely used in transmission lines, especially in ultra-high voltage lines. Conductive silicone rubber is used in electronic computers, telephone and other instruments of electrical contact parts and liquid crystal display contact parts. Wire and cable made of flame retardant and radiation-resistant silicone rubber are widely used in atomic power stations. Silicone rubber heating sheet and heating belt are used to control the working temperature of various precision instruments and oil pipelines. They are used as heating blankets for physiotherapy heat compresses in medical treatment. RT-silicone rubber can be used as waterproof, moisture-proof and shock-proof potting material.
Silicone rubber has been widely used in the pump seals of dishwashers and washing machines because of its heat-resistant washing liquid properties. Silicone rubber is ideal for gaskets on coffee POTS, fryers, and steam irons. The gasket of stereo earphone ear and head is changed to silicone rubber, which can eliminate external noise and is soft and comfortable.
