Haotian Brand High Temperature Sleeve Features and Applications

　1.Safe and environmentally friendly, protecting workers' health
　　Alkali-free fiberglass has excellent tensile strength, will not wrinkle or break, is resistant to vulcanization, produces no smoke, is halogen-free, non-toxic, oxygen is non-flammable, and has good insulation properties. After being cured with organic silicone, its safety and environmental protection performance is further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to human beings and the environment.
　2.Excellent high-temperature resistance
　　The surface of the high-temperature sleeve contains both 'organic groups' and 'inorganic structures'. This special composition and molecular structure combine the properties of organic materials with the functions of inorganic materials. Compared to other polymer materials, its standout feature is its high-temperature resistance. With a main chain structure of silicon-oxygen (Si－O), the bond energy of the C-C bond is 82.6 kcal/mole, while the bond energy of the Si-O bond in organic silicone is 121 kcal/mole. Therefore, it has high thermal stability, and the chemical bonds of the molecules do not break or decompose under high temperatures (or radiation exposure). Organic silicone can withstand high temperatures as well as low temperatures, making it usable over a wide temperature range. Whether in chemical properties or physical mechanical properties, the changes with temperature are minimal. 
　3.Splash-proof, multiple protections
　　In the smelting industry, the medium temperature inside electric furnaces is extremely high, making it easy to form high-temperature splashes (the same applies in the welding industry). When cooled and solidified, they can form slag on pipelines or cables, which can harden the rubber on the outer layer of the pipelines or cables, leading to brittleness and rupture. This can damage unprotected equipment and cables. The high-temperature sleeve, coated with multiple layers of silicone, can provide multiple safety protections, with a high-temperature resistance of up to 1300 degrees Celsius, effectively blocking splashes of molten iron, copper, 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 pipelines, valves, or equipment have very high internal temperatures. If protective materials are not used for covering, it can easily lead to personnel burns or heat loss. Haotian high-temperature sleeves have better thermal stability than other polymer materials, and have radiation resistance and thermal insulation functions, preventing accidents and reducing energy consumption. They also prevent the heat of the medium inside the pipes from directly transferring to the surrounding environment, which could cause excessive temperatures in the workshop, thus saving cooling costs. 
　5.Damp-proof, oil-proof, climate aging resistant, pollution resistant, prolonging equipment lifespan
　　The high-temperature sleeve possesses strong chemical stability, and does not react with substances like oil, water, acids, and alkalis in organic silicone, and can be used long-term without aging within 260℃. Under natural conditions, its lifespan can reach several decades, maximizing the protection of pipelines, cables, and equipment in such environments, greatly extending their service life. 
　6.Ozone resistant, voltage resistant, arc resistant, corona resistant
　　Because the surface is coated with organic silicone, its main chain is -Si－O－, which makes it resistant to decomposition by ultraviolet light and ozone. The high-temperature sleeve has excellent electrical insulation properties, with dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity ranking among the best in insulating materials. Moreover, their electrical properties are minimally affected by temperature and frequency. Therefore, they are a stable electrical insulation material and are widely used in the electronics and electrical industries.
　7.Flame retardant, reducing the incidence and spread rate of fires
　　If flammable or toxic media are transported in the pipes, leaks can easily cause fires or casualties; cables often ignite due to localized high temperatures. The high-temperature sleeve is woven from extremely heat-resistant fiberglass, and the surface silicone is added with suitable flame retardants and other special raw materials, giving it excellent flame-retardant properties. Even in the event of a fire, it can prevent the spread of flames, and still protect the internal pipelines intact for a longer time, providing ample time for the rescue of data, documents, and other important information.  7 Common Application Areas:

　　High-temperature areas, heating areas of cables, fluid pipelines, rolling mill cables, oil pipes, saw-cut edge cables, generator sets, electrical voltage equipment, large constructions, hydraulic systems, automotive wiring harnesses, and exhaust pipes in industries such as steel, smelting, shipbuilding, and chemical industry.
