The car industry

The application of silica gel in the automotive industry is growing rapidly. Silica gel (especially silica gel with various characteristics) can be resistant to the erosion of fuel oil and lubricating oil, improve the performance of automobile parts and reduce maintenance costs. It can be used for automobile ignition line, spark plug protective cover, hose for heating and radiator, muffler lining, battery connector and fuel pump made of fluorine silicone. With the development of vehicle electronic electrification, room temperature curing silica gel is widely used in electronic parts, electrical assembly parts of the pouring sealant, windshield glass, car body around the seal and mirror bonding sealant.

Electronics, electrical industry

Electronics and electrical industry is the earliest use of silica gel as insulating material, a larger demand for a field. Silica gel is mainly used for TV anode cover, high voltage protective cover, high voltage lead line, refrigerator defroster wire, power or signal transmission wire and cable. Insulators made of silica gel will be widely used in transmission lines, especially ultra high voltage lines, instead of ceramics. Conductive silica gel is used for electrical contacts of electronic computers, telephones and other instruments and liquid crystal display contacts. Flame retardant and radiation resistant silicone made of wire, cable is widely used in energy power stations. Silica gel 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 blanket for physiotherapy hot packs in medical treatment. Room temperature solidified silica gel can be used as waterproof, moisture-proof and shockproof potting material.

Silica gel has been widely used in the pump seal of dishwasher and washing machine because of its heat-resistant washing liquid performance. Silica gel is ideal for gaskets on appliances such as coffee pans, electric fryers and steam irons. The padding of the ear and head of stereo earphone is silica gel, which can eliminate the external noise and is soft and comfortable.

The aerospace industry

Silica gel is an indispensable high-performance material in the aerospace industry. It can withstand the ultra-cold space and the scorching heat of returning atmosphere, prolong the life of aircraft parts, reduce maintenance costs and reduce accidents. It is mainly used for aircraft body hole seals, electrical connectors, sealing switches, dust and waterproof covers, gaskets, "O" sealing rings, oxygen masks, regulating diaphragm, hot air ducts and radar wireless shock absorbers. Burn resistant silica gel is suitable for rocket fuel valve, power source cable and rocket launcher cover coating, so as not to be burned by rocket jet flow. Room temperature curing silica gel can be used as airtight sealing, window frame sealing and shockproof, moisture-proof potting material.

Construction industry

Silica gel has good weather resistance and construction, as adhesive sealant in the construction industry has been widely used, more than other types of sealant. In recent years, low modulus and high elongation type two-component sealant has been developed, which is used for large joint movement of concrete prefabricated parts and curtain walls and other large components. Room temperature curing silica gel is also used for sealing asbestos cement board joints, bathroom brick joints and toilet appliances. With the decline of rubber price in the future, the scope of application will be further expanded, such as in the application of highway joints instead of asphalt and neoprene. High temperature solidified silica gel sponge strips are used as sealing panels for doors and Windows of buildings.

The medical field

Silica gel has good biocompatibility, small reaction to the body, stable performance, low blood coagulation, can withstand high temperature and high pressure cooking, and can be processed into various shapes of products, such as film, sponge, air bag, is currently the most widely used in medicine a material.
