Haotian Brand Fireproof SleeveFeatures and Applications

　1.Safe and environmentally friendly, protecting workers' health
　　Alkali-free glass fiber has excellent tensile strength, is not prone to wrinkling or breaking, is sulfur-resistant, smoke-free, halogen-free, non-toxic, non-combustible in pure oxygen, 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 pose great harm to human health and the environment.
　2.Excellent high-temperature resistance
　　The surface of the high-temperature sleeve contains both organic groups and inorganic structures in its silicone composition. This unique composition and molecular structure allow it to combine the properties of organic materials with the functions of inorganic ones. Compared to other polymer materials, its outstanding feature is its high-temperature resistance. With a Si-O bond as the main chain structure, the bond energy of C-C is 82.6 kcal/mol, while the bond energy of Si-O in silicone is 121 kcal/mol. Therefore, it has high thermal stability, and its chemical bonds do not break or decompose under high temperatures (or radiation exposure). Silicone can withstand both high and low temperatures and can be used over a wide temperature range. Its chemical and physical mechanical properties change very little with temperature. 
　3.Splash-proof, multi-layer protection
　　In the smelting industry, the medium temperature inside electric furnaces is extremely high, easily leading to high-temperature splashes (this is also the case in the welding industry). When cooled and solidified, it forms slag on pipelines or cables, which can cause the rubber on the outer layer of the pipeline or cable to harden and eventually become brittle and crack. This can damage unprotected equipment and cables. The high-temperature sleeves coated with multiple layers of silicone can provide 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.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, it can easily cause burns to personnel or heat loss. Haotian high-temperature sleeves have 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 inside the pipeline from directly transferring to the surrounding environment, which would cause excessive workshop temperatures, thus saving cooling costs. 
　5.Moisture-proof, oil-proof, weather aging-resistant, pollution-resistant, extending equipment lifespan
　　High-temperature sleeves have strong chemical stability, and the silicone does not react with oils, water, acids, or bases. They can be used long-term without aging below 260 degrees Celsius, with a service life of several decades in natural environments, maximizing the protection of pipelines, cables, and equipment in such environments, significantly extending their service life. 
　6.Ozone-resistant, voltage-resistant, arc-resistant, corona-resistant
　　Due to the surface coated with silicone, which has a main chain of -Si-O-, it is not easily decomposed by ultraviolet light and ozone. High-temperature sleeves have good electrical insulation properties, with dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity all ranking among the best in insulating materials, and their electrical performance is minimally affected by temperature and frequency. Therefore, they are a stable electrical insulating material widely used in the electronics and electrical industries.
　7.Flame-retardant, reducing the incidence and spread of fire
　　If the medium transported in the pipeline is flammable or toxic, leaks can easily cause fires or casualties; cables often ignite due to localized high temperatures. High-temperature sleeves are made from extremely heat-resistant glass fiber woven materials, and the silicone on their surface contains suitable flame retardants and other special materials, giving them excellent flame-retardant properties. Even in the event of a fire, they can prevent the spread of flames and still protect the internal pipelines intact for an extended period, providing ample time for the rescue of important data and information.  7 Common Areas of Use:

　　High-temperature areas in industries such as steel, smelting, shipbuilding, and chemicals; heating area cables, fluid pipelines, rolling mill cables, oil pipelines, saw-cut perimeter cables, generator sets, electrical voltage equipment, large buildings, hydraulic systems, automotive wire harnesses, and exhaust pipes, etc.
