Silicone rubber has unique comprehensive properties, especially its biocompatibility is a key characteristic. It has been successfully used in other occasions where rubber is ineffective, solving many technical problems, and meeting various needs of modern industry and daily life. Like other rubbers, silicone rubber can be processed into various profiles, rubber tubes, rubber strips, rubber rolls, rubber blanket and other products; Room temperature vulcanized silicone rubber can be applied in large area on site and is easy to use.

(1) Automobile industry
The application of silicone rubber in the automobile industry is growing rapidly. Silicone rubber (especially silicone rubber with various characteristics) can resist the corrosion of fuel and lubricating oil, improve the service performance of various automobile parts, and reduce maintenance costs. It can be used for automobile ignition wire, spark plug protective cover, heating and radiator hose, muffler lining, battery connector and fuel pump made of fluorosilicone rubber. With the development of vehicle electronic electrification, RTV silicone rubber is widely used as the sealant for electronic parts, potting materials for electrical assemblies, windshield glass, car body seals and reflectors.

(2) Electronics and electrical industry
The electronic and electrical industries are one of the fields where silicone rubber was first used as insulating materials and has a large demand. Silicone rubber is mainly used for TV anode cover, high-voltage protective cover, high-voltage outgoing line, refrigerator defroster wire, power or signal transmission wire and cable, etc. Insulators made of silicone rubber will replace ceramic products and be widely used in transmission lines, especially ultra-high voltage lines. Conductive silicone rubber is used for electric contact parts of electronic computers, telephones and other instruments and LCD display contact parts. Wires and cables made of flame retardant and radiation resistant silicone rubber are widely used in atomic power stations. Silicone rubber heating sheets and belts are used to control the working temperature of various precision instruments and oil pipelines, and are used as heating blankets for physiotherapy hot applicators in medical treatment. Room temperature vulcanized silicone rubber can be used as a potting material for waterproofing, moisture-proof and shockproof.

Silicone rubber has been widely used in the pump seals of dishwashers and washing machines due to its heat-resistant detergent performance. Silicone rubber is very suitable for use as a gasket on coffee pots, electric fryers, steam irons and other appliances. The padding of stereo earphone ear and head is replaced by silicone rubber, which can eliminate external noise and is soft and comfortable.

(3) Aerospace industry
Silicone rubber is an indispensable high-performance material in the aerospace industry. It can withstand the supercooling of 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 hole seals, electrical connectors, sealing switches, dust and waterproof covers, gaskets, "O" type sealing rings, oxygen masks, control diaphragms, hot air ducts, radar wireless shock absorbers, etc. of jet engines and hydraulic devices. Burn resistant silicone rubber is suitable for coating rocket fuel valve, power source cable and rocket launching well cover to avoid being burnt by rocket jet flow. Room temperature vulcanized silicone rubber can be used as air tight seal for machine body, window frame seal, shockproof and moisture-proof potting material.
(4) Construction industry
Silicone rubber has good weather resistance and workability. As a bonding sealant, it has been widely used in the construction industry, surpassing other types of sealants. In recent years, a low modulus and high elongation two-component sealant has been developed, which is used for large components such as concrete prefabricated parts and curtain walls with large joint movement. Room temperature vulcanized silicone rubber is also used for sealing asbestos cement board joints, bathroom tile joints and toilet appliances. With the decline of rubber price in the future, the application scope will be further expanded, such as replacing asphalt and neoprene in the application of highway joints. High temperature vulcanized silicone rubber sponge strip is used as the door and window sealing strip of buildings.

(5) Medical field
Silicone rubber has good biocompatibility, small reaction to the body, stable performance, low blood coagulation, can withstand high temperature and high pressure cooking for many times, and can be processed into products of various shapes, such as films, sponges, air bags. It is currently the most widely used material in medicine.
