1. Safety and environmental protection, protect the health of workers
The alkali-free glass fiber itself has extremely strong tensile force, will not be wrinkled and broken, is vulcanized, is smoke-free, halogen-free, non-toxic, pure oxygen, non-combustible, and has good insulation characteristics. After the organic silica gel is cured, its safety and environmental protection performance is strengthened, and its protection is effective. Workers are healthy and reduce the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to the human body and the environment.

2. Superior high temperature resistance
The organosilicon structure on the surface of the high temperature resistant casing contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it integrate the characteristics of organic substances and the functions of inorganic substances. Compared with other polymer materials, its most prominent feature is its high temperature resistance. With silicon-oxygen (Si-O) bond as the main chain structure, the bond energy of C-C bond is 82.6 kcal/mole, and the bond energy of Si-O bond is 121 kcal/mole in organosilicon, so Its thermal stability is high, and the chemical bonds of molecules will not break or decompose under high temperature (or radiation exposure). Silicone is not only resistant to high temperature, but also resistant to low temperature, and can be used in a wide temperature range. Whether it is chemical properties or physical mechanical properties, the change with temperature is very small.

3. Splash-proof, multiple protection
In the smelting industry, the temperature of the medium in the electric furnace is extremely high, which is easy to form high-temperature splash (the same is true in the electric welding industry). After cooling and solidification, slag is formed on the pipe or cable, which will harden the rubber on the outer layer of the pipe or cable, and finally Embrittlement and cracking. Furthermore, unprotected equipment and cables will be damaged. The high temperature resistant casing coated with multiple silicone gels can achieve multiple safety protections. The maximum temperature can be as high as 1300 degrees Celsius, which can effectively block the high temperature melting of molten iron, molten copper, and molten aluminum. Splashing of objects to prevent damage to surrounding cables and equipment.

4. Thermal insulation, energy saving and consumption reduction, radiation resistance
In high-temperature workshops, many pipelines, valves or equipment have very high internal temperatures. If they are not covered with protective materials, it is easy to cause burns or heat loss. Baite high temperature resistant casing has better thermal stability than other polymer materials, as well as radiation resistance and thermal insulation, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipeline from being directly transferred to the surrounding environment The temperature in the workshop is too high, saving the cost of cooling.

5. Anti-moisture, anti-oil, anti-climatic aging, anti-pollution, and prolong the service life of equipment
The high temperature resistant casing has strong chemical stability. The organic silicon does not react to oil, water, acid, alkali and other substances. It can be used for a long time without aging within 260°C. The service life under natural environment can reach several decades. It can protect the pipes, cables and equipment in these occasions to the greatest extent, and greatly extend their service life.

6. Ozone resistance, voltage resistance, arc resistance and corona resistance
Because the surface is coated with organic silica gel, its main chain is -Si-O-, and there is no double bond, so it is not easy to be decomposed by ultraviolet light and ozone. High temperature resistant bushings have good electrical insulation properties. Their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. The impact is very small. Therefore, they are a kind of stable electrical insulating materials, which are widely used in the electronics and electrical industries.
