Application of silicone rubber
Silicone rubber has unique comprehensive properties, especially the biocompatibility of silicone rubber is a key characteristic. It has been successfully used in occasions where other rubbers are ineffective, solved many technical problems, and met the needs of modern industry and society. various needs of daily life. Like other rubbers, silicone rubber can be processed into various profiles, rubber hoses, rubber strips, rubber rollers, rubber cloths and other products; room temperature vulcanized silicone rubber can be used for large-scale construction on site and is easy to use.
The application of silicone rubber in the automobile industry is growing rapidly. Silicone rubber (especially silicone rubber with various characteristics) can resist the erosion of fuel and lubricating oil, improve the performance of various parts of the automobile, and reduce maintenance costs. It can be used in automobile ignition wires, spark plug protection covers, heating and radiator hoses, muffler linings, battery connectors, and fuel pumps made of fluorosilicone rubber. With the development of vehicle electronics and electrification, room temperature vulcanized silicone rubber is widely used in potting materials for electronic parts, electrical assemblies, windshields, seals around the car body, and adhesive sealants for reflectors.
(2) Electronics and electrical industry
The electronics and electrical industries are the earliest fields where silicone rubber is used as an insulating material and has a large demand. Silicone rubber is mainly used in TV anode covers, high voltage protective covers, high voltage lead wires, refrigerator defroster wires, power or signal transmission wires and cables, etc. Insulators made of silicone rubber will replace ceramic products and are widely used in power transmission lines, especially ultra-high voltage lines. Conductive silicone rubber is used in electrical contacts and liquid crystal display contacts of electronic computers, telephones and other instruments. Wires and cables made of flame-retardant and radiation-resistant silicone rubber are widely used in atomic power stations. Silicone rubber heating sheets and heating belts are used to control the working temperature of various precision instruments and oil pipelines, and are used as heating blankets for physiotherapy heat compresses in medical treatment. Room temperature vulcanizing silicone rubber can be used as a potting material for waterproof, moisture-proof and shock-proof.
Silicone rubber has been widely used in pump seals of dishwashers and washing machines due to its heat-resistant detergent properties. Silicone rubber is ideal for use as gaskets on appliances such as coffee pots, electric fryers and steam irons. The ear and head pads of the stereo earphones are made of 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 ultra-cold space and the scorching heat of returning to the atmosphere, prolong the life of aircraft parts, reduce maintenance costs, and reduce accidents. Mainly used for aircraft body cavity seals, electrical connectors, sealed switches, dustproof and waterproof covers, gasket gaskets, "O" rings for jet engines and hydraulic devices, oxygen masks, regulating diaphragms, hot air ducts and Radar wireless shock absorbers, etc. Burn-resistant silicone rubber is suitable for rocket fuel valves, power source cables and rocket silo cover coatings, so as not to be burned by rocket jets. Room temperature vulcanized silicone rubber can be used as the airtight seal of the body, window frame seal and shockproof, moisture-proof potting material.
(4) Construction industry
Silicone rubber has good weather resistance and workability, and has been widely used as an adhesive sealant in the construction industry, surpassing other types of sealants. In recent years, a low-modulus 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. RTV silicone rubber is also used for sealing joints of asbestos cement boards, bathroom tile joints and toilet utensils. With the decline of rubber prices in the future, the scope of application will be further expanded, such as replacing asphalt and neoprene in the application of road joints. High-temperature vulcanized silicone rubber sponge strips are used as sealing strips for doors and windows of buildings.
(5) Medical field
Silicone rubber has good biocompatibility, small reaction to the body, stable performance, low hemagglutination, can withstand high temperature and high pressure for multiple cooking, and can be processed into products of various shapes, such as films, sponges, and air bags. One of the most widely used materials in medicine.
(6)Other fields
In addition to the various applications mentioned above, the application of silicone rubber in the fields of textiles, printing, machinery, plastics, chemistry, papermaking, food and cosmetics has also increased significantly. Typical products are rollers made of silicone rubber for heat setting of fabrics, plastics, embossing, calendering and fusing in copiers. Air-conditioning windows made of silicone rubber films have been used to store fruits and vegetables. In addition, silicone rubber has also achieved good results as a sealing material in textile high-temperature equipment and equipment with high concentrations of alkali, sodium hypochlorite and hydrogen peroxide.
