After vulcanization, liquid silicone rubber has excellent high and low temperature resistance, weather resistance, water repellency, electrical insulation, physiological inertia, etc., and has been widely used in national defense, medical and health, and people's daily life. Silicone rubber can be divided into high temperature (heating) vulcanization type and room temperature vulcanization type according to its vulcanization temperature. High temperature vulcanization type silicone rubber is mainly used for making various silicone rubber products, while room temperature vulcanization type Mixture, potting material or mold.

Aerospace and aviation industry

Silicone rubber can withstand extreme temperatures and remain stable under extreme stress conditions and harsh environments without affecting its use. Therefore, it can be used to manufacture door and window and panel seals, body cavity seals, and gaskets inside and outside aircraft or spacecraft. Various components such as gaskets, sealing switches, sealing rings of engines and hydraulic devices, and cable insulation. The ablation resistant silicone rubber can be used for rocket fuel valve, launcher cover coating and power source cable, etc. Room temperature vulcanized silicone rubber can also be used as a potting material for air-tight sealing, window frame sealing, moisture-proof and shock-proof. Fluorosilicone rubber has excellent oil resistance and is an ideal material for fuel control diaphragms, hydraulic pipelines and cable clamps. Both the ground and space station computers use keyboards made of silicone rubber. Silicone rubber has become one of the important high-performance materials in the aerospace and aviation industries.

Auto industry

Silicone rubber has excellent properties such as insulation, heat resistance, oil resistance, and aging resistance, which can improve the performance of various parts of the automobile and can be used in almost all aspects of the automobile industry. Silicone rubber is used in automobile sealing gaskets and other seals. It can provide strong and long-lasting sealing protection for all devices from headlights to oil filters. It is leak-proof and durable, and will not crack or break under extreme temperature and pressure; For connectors, it can protect the electrical connections of automobile connectors, including electrical plugs and sockets, to avoid moisture and corrosion; for spark plug protective covers, it can prevent spark plugs from splashing, damp, and dust adhesion, which is good for the ignition system to work well. It is important, but also has good electrical insulation properties and heat resistance; used for radiators, heat exchangers and water pump gaskets to ensure that these parts are not corroded during the process of delivering antifreeze; it can also be used for cylinder head gaskets To improve oil resistance.

Electronics industry

The extremely professional applications in the electronics industry put high demands on sealing materials, and the excellent properties of silicone rubber can fully meet the requirements of the electronics industry. Silicone rubber can be used as a seal in the engine industry production field that has extremely high requirements for heater hoses and coolant hoses; it can be used as the main material of insulating parts for engine gaskets, electronic packaging, control device gaskets, circuits and retreats. A special component for coupling noise reduction; it can also be used as the main material of various electronic tubes or electrical components for coating and sealing. It has the effects of moisture-proof, dust-proof, shock-proof and improved electrical performance. Since silicone rubber has a wide operating temperature and burst strength, the use of silicone rubber to make hoses can avoid kinks and vacuum collapse. In the cable field, silicone rubber is used for indoor and outdoor cable terminal connectors, insulation devices and surge arresters. High-pressure liquid silicone rubber is very suitable for power transmission and distribution.

Medical field

Medical silicone rubber has been widely and importantly applied in the fields of life sciences, medical equipment, medicine and so on. In addition to meeting the basic requirements of medical polymer materials, silicone rubber also has the characteristics of heat resistance, cold resistance, non-toxicity, biological aging resistance, minimal negative effects on human tissues, and good physical and mechanical properties, making it the most typical Medical polymer materials.

Silicone rubber can be used to manufacture key parts of medical machinery, including artificial heart-lung machine blood transfusion pump tube, membrane type artificial heart-lung machine, fetal aspirator and artificial blood circulation device, etc.; it can be used as an organ or tissue substitute, and products that are left in the body for a long time include cerebral accumulation. Water drainage devices, artificial tympanic membranes, artificial tendons, artificial heart valve accessories, etc., are kept in the body for a short period of time, and the products that play the role of rehydration, rescue, drainage and injection, anti-adhesion or defoaming are intravenous catheters, peritoneal dialysis tubes, and vascular gastroscope sets. Tube, catheter, nasal cannula, etc. Silicone rubber has also been widely used in cosmetic and prosthetic surgery, such as facial, skull and chest cosmetic surgery and internal organ repair. Medical silicone tube is the fastest growing and most versatile product among silicone rubber products. Its development trend is miniature, thin-walled, multi-cavity, and one tube with multiple functions, such as sampling and testing, as well as lavage and infusion.

Other

Silicone rubber is also widely used in machinery, construction, textile, chemical, light industry, printing and other industries. It is used as insulation, encapsulation, caulking, sealing, moisture-proof, and earthquake-resistant materials. It can also be used to make rollers. As a soft mold material, it is widely used in the reproduction and manufacture of cultural relics, handicrafts, toys, mechanical parts, etc. Silicone rubber sealed semiconductors can be used for high-frequency communications such as industrial motors, locomotives and power supplies that require high-voltage switches, mobile phone base stations, satellites, and radars. Toys made of silicone rubber are not afraid of biting, have an excellent touch, are easy to color and can be sterilized at high temperature, and the made game equipment is durable and not afraid of wind and rain.
