The silicone material is a new type of synthetic material with excellent performance and wide application. The silicone material is divided into several categories such as silicone oil and its derivatives, silicone rubber, silicone resin, and silicon coupling agent.
Silicone O-ring Manufacturers introduced that silicone has excellent heat resistance, cold resistance, dielectric properties, ozone resistance, and atmospheric aging resistance, and has a very wide range of applications. For long-term use up to +350°C (or higher temperature), pay attention to the extreme temperatures at both ends, and different formulations are required to achieve
1. Heat resistance: Silicone has very good heat resistance. After testing, it can be used almost all the time in a high-temperature environment of 150 ℃ without any change in performance and can be used continuously for 10,000 hours in an environment of 200 ℃. Therefore, it is widely used in electrical equipment with extremely high-temperature environment requirements. For example supercapacitors for new energy vehicles, shock-proof gaskets for high-voltage equipment, etc.
2. Cold resistance: ordinary rubber has lost its own characteristics of rubber under the condition of minus 20℃-30℃, while silicone still has good elasticity at minus 60℃-70℃, and the lower temperature silicone O-ring The silicone sealing ring is made with special formula can also withstand the test of extremely low-temperature environment, such as a low-temperature sealing ring. However, it should be noted that silica gel products are not recommended to be used in most thickened solvents, oils, thickened acids, and diluted sodium hydroxide. The special chemical structure of silicone materials endows them with a series of excellent properties and has been widely used in aerospace, aviation, ships, automobiles, electronic appliances, light industry and textiles, petrochemicals, building materials, energy development, medical care, and other fields.
