Haotian Brand Hydraulic Hose Fireproof SleeveFeatures and Applications

　1.Safe and environmentally friendly, protecting workers' health
　　Non-alkali glass fiber has extremely high tensile strength, does not wrinkle or break, is resistant to vulcanization, produces no smoke, is halogen-free and non-toxic, is pure oxygen non-flammable, and has good insulation properties. After being cured with organic silicone, its safety and environmental protection features are further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose great harm to both human health and the environment.
　2.Excellent high-temperature resistance
　　The surface organic silicone structure 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 high-temperature resistance. With a silicon-oxygen (Si－O) bond as the main chain structure, the bond energy of C－C is 82.6 kcal/mole, while the bond energy of Si－O in organic silicone is 121 kcal/mole, thus providing high thermal stability. Under high temperatures (or radiation exposure), the chemical bonds of the molecules do not break or decompose. Organic silicone can not only withstand high temperatures but also low temperatures, making it suitable for use across a wide temperature range. Both its chemical properties and physical mechanical properties show little variation with temperature changes. 
　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 to the electric welding industry). After cooling and solidification, slag can form on the pipelines or cables, causing the outer layer of rubber to harden and eventually become brittle and crack. This can damage unprotected equipment and cables. The high-temperature sleeve, covered with multiple layers of silicone, provides multiple safety protections, with high-temperature resistance up to 1300 degrees Celsius, effectively blocking splashes of molten iron, molten copper, and molten aluminum, 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. Without protective materials, it is easy to cause burns to personnel or heat loss. The Haotian high-temperature sleeve has better thermal stability than other polymer materials and offers radiation resistance and insulation, preventing accidents and reducing energy consumption. It can also prevent the heat from the medium in the pipeline from being directly transferred to the surrounding environment, thereby preventing excessive workshop temperatures and saving cooling costs. 
　5.Moisture-proof, oil-proof, climate aging-resistant, pollution-resistant, extending equipment lifespan
　　The high-temperature sleeve has strong chemical stability, and organic silicone does not react with oil, water, acids, or bases. It can be used for a long time without aging at temperatures below 260 degrees Celsius, with a service life of several decades in natural conditions, maximizing the protection of pipelines, cables, and equipment in these environments, greatly extending their service life. 
　6.Ozone-resistant, voltage-resistant, arc-resistant, corona-resistant
　　Because the surface is coated with organic silicone, which has a main chain of -Si－O－, the bonds present make 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, and their electrical performance is little affected by temperature and frequency. Therefore, they are a stable electrical insulating material widely used in electronics and electrical industries.
　7.Flame-retardant, reducing the incidence and spread of fires
　　If the medium transported in the pipeline is flammable or toxic, leaks can easily cause fires or casualties; cables often catch fire due to localized high temperatures. The high-temperature sleeve is made of highly heat-resistant glass fiber woven material, and the surface silicone incorporates suitable flame-retardant agents 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 an extended period, providing ample time for the rescue of data, documents, and other important information.
