Haotian Brand High Temperature Sleeve Characteristics and Applications

　1.Safe and environmentally friendly, protecting workers' health
　　Alkali-free fiberglass has excellent tensile strength, is wrinkle-resistant, sulfur resistant, smoke-free, halogen-free, non-toxic, non-flammable in pure oxygen, and has good insulation properties. After being cured with silicone rubber, its safety and environmental performance are further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to human health and the environment.
　2.Outstanding high-temperature resistance
　　The silicone structure on the surface of the high-temperature sleeve contains both 'organic groups' and 'inorganic structures'. This special composition and molecular structure combine the characteristics of organic materials with the functions of inorganic materials. Compared to other polymer materials, its standout feature is high-temperature resistance. With a main chain structure of silicon-oxygen (Si-O) bonds, the bond energy of C-C bonds is 82.6 kilocalories/mole, while the bond energy of Si-O bonds in silicone is 121 kilocalories/mole, which gives it high thermal stability. Under high temperatures (or radiation exposure), the chemical bonds of the molecules do not break or decompose. Silicone not only withstands high temperatures but also low temperatures, allowing it to be used over a wide temperature range. Both its chemical properties and physical mechanical properties change little with temperature fluctuations. 
　3.Splash-proof, multiple protections
　　In the smelting industry, the medium temperature inside electric furnaces is extremely high, making it easy to generate high-temperature splashes (the same goes for the welding industry). After cooling and solidifying, this can form slag on pipes or cables, causing the rubber outer layer to harden and become brittle, leading to cracks. This can damage unprotected equipment and cables. The high-temperature sleeve with multiple layers of silicone coating provides multiple safety protections, with high-temperature resistance up to 1300 degrees Celsius, effectively blocking splashes of molten iron, molten copper, molten aluminum, and other high-temperature molten materials, preventing damage to surrounding cables and equipment.
　4.Thermal insulation, energy saving, radiation resistance
　　In high-temperature workshops, many pipes, valves, or equipment have very high internal temperatures. Without protective covering, it can easily lead to personnel burns or heat loss. Haotian high-temperature sleeves have better thermal stability compared to other polymer materials, as well as radiation resistance and thermal insulation properties to prevent accidents, reduce energy consumption, and prevent the heat of the medium in the pipes from directly transferring to the surrounding environment, which can lead to excessive workshop temperatures and save cooling costs. 
　5.Moisture-proof, oil-proof, climate aging resistance, pollution resistance, extending equipment lifespan
　　High-temperature sleeves have strong chemical stability, and silicone does not react with substances such as oil, water, acids, and bases, allowing for long-term use without aging up to 260℃. Under natural environmental conditions, their lifespan can reach several decades, providing maximum protection for pipes, cables, and equipment in such environments, greatly extending their service life. 
　6.Ozone resistance, voltage resistance, electric arc resistance, corona resistance
　　The surface is coated with silicone rubber, which has a main chain of -Si-O- bonds, making it difficult to decompose under ultraviolet light and ozone. The high-temperature sleeve has excellent electrical insulation properties, with low dielectric loss, voltage resistance, electric arc resistance, corona resistance, volume resistivity, and surface resistivity, all ranking among the best in insulating materials. Additionally, their electrical performance is minimally affected by temperature and frequency. Therefore, they are a stable electrical insulation material widely used in the electronics and electrical industries.
　7.Flame retardant, reducing the incidence and spread of fires
　　If the medium carried in the pipes is flammable or toxic, leaks can easily lead to fires or casualties; cables can also catch fire due to localized high temperatures. The high-temperature sleeve is made of extremely heat-resistant fiberglass, and the silicone surface is added with appropriate flame retardants and other special materials, giving it excellent flame retardancy. Even in the event of a fire, it can prevent the spread of flames and still protect internal pipelines for a considerable time, providing ample time for the rescue of data, materials, and other important information.  7 Common Usage Areas:
