The silicone structure on the surface of high temperature resistant casing contains both “organic group” and “inorganic structure”. This special composition and molecular structure make it a combination of organic properties and inorganic functions. Compared with other polymer materials, the most prominent one is high temperature resistance. The bond energy of C-C bond is 82.6 kcal/molecule. The bond energy of Si-O bond is 121 kcal/molecule in organic silicon. Therefore, the thermal stability of Si-O bond is high. The chemical bond of C-C bond is continuously cracked and does not decompose under high temperature (or irradiation). Silicone is not only resistant to high temperature, but also to low temperature, and can be used in a wide range of temperatures. Both chemical and physical properties vary little with temperature.
In the smelting industry, the medium temperature in the electric furnace is extremely high, and it is easy to form high temperature splash (welding industry is also the case). The slag formed on the pipe or cable after cooling solidification will harden the rubber of the pipe or cable outer layer, and eventually brittle fracture. Then damaged unprotected equipment and cables, through multi-channel silica gel coated high-temperature sleeve, can achieve multiple safety protection, the highest temperature can be as high as 1300 degrees Celsius, can effectively prevent the splash of molten iron, molten copper, molten aluminum and other high-temperature melts, to prevent damage to the surrounding cables and equipment.
