The application of silica gel in automobile industry is growing rapidly. Silica gel (especially silica gel with various characteristics) can resist the erosion of fuel and lubricating oil, improve the service performance of automobile components, and reduce maintenance costs. It can be used for automobile ignition wire, spark plug protective cover, hose for heating and radiator, muffler lining, battery connector and refueling pump made of fluorosilicone. With the development of vehicle electronic electrification, room temperature curing silica gel is widely used in filling sealant for electronic parts and electrical assembly parts, windshield glass, sealing around car body and adhesive sealant for reflector.

The electronic and electrical industry is an area where silica gel is the earliest used insulating material and has a large demand. Silica gel is mainly used for TV anode cover, high voltage protection cover, high voltage outgoing line, refrigerator defroster wire, power or signal transmission wire and cable. The insulator made of silica gel will replace ceramic products and be widely used in transmission lines, especially ultra-high voltage lines. Conductive silica gel is used for electric contact parts of electronic computers, telephones and other instruments, as well as contact parts of liquid crystal display.

Silica gel is an indispensable high-performance material in the aerospace industry. It can withstand the super cold in space and the heat of returning to the atmosphere, extend the life of aircraft parts, reduce maintenance costs and reduce accidents. It is mainly used for aircraft body cavity seal, electric connector, sealing switch, dust and waterproof cover, gasket, O-ring of jet engine and hydraulic device, oxygen mask, regulating diaphragm, hot air duct and radar wireless shock absorber.

Silica gel has good weather resistance and construction performance. As a kind of adhesive sealant, it has been widely used in the construction industry. In recent years, a low modulus and high elongation two-component sealant has been developed, which is used for large-scale components such as precast concrete and curtain wall with large joint movement. Room temperature curing silica gel is also used for sealing the joints of asbestos cement board, the joints of bathroom bricks and the sealing of toilet appliances.
