Haotian Brand High-Temperature Resistant Sleeve Characteristics and Applications

　1.Safe and environmentally friendly, protecting workers' health
　　Alkali-free glass fiber itself has strong tensile strength, does not wrinkle or break, is resistant to vulcanization, smoke-free, halogen-free, non-toxic, pure oxygen non-combustible, and possesses good insulation properties. After curing with organic silicone rubber, 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 significant hazards 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 special composition and molecular structure give it the characteristics of organic materials and the functions of inorganic materials. Compared to other polymer materials, its outstanding feature is its high-temperature resistance. With a silicon-oxygen (Si－O) bond as the main chain structure, the bond energy of C－C is82.6 kcal/mole, while the bond energy of Si－O in organic silicon is121 kcal/mole, thus its thermal stability is high. Under high temperatures (or radiation exposure), the molecular chemical bonds do not break or decompose. Organic silicone not only withstands high temperatures but also low temperatures, usable over a wide temperature range. Both its chemical properties and physical mechanical properties change very little with temperature. 
　3.Splash-proof, multiple protections
　　In the metallurgical industry, the medium temperature inside electric furnaces is extremely high, easily leading to high-temperature splashes (the same applies to the welding industry). Once cooled and solidified, they form slag on pipelines or cables, causing the rubber on the outer layer of the pipelines or cables to harden and eventually become brittle and crack. This can damage unprotected equipment and cables. The high-temperature sleeve, coated with multiple layers of silicone, provides multiple safety protections, with a high temperature resistance of up to 1300 degrees Celsius, effectively blocking splashes of molten iron, molten copper, molten aluminum, and other high-temperature molten substances, preventing damage to surrounding cables and equipment.
　4.Insulation, energy saving and consumption reduction, radiation resistance
　　In high-temperature workshops, many pipelines, valves, or equipment have very high internal temperatures. If not covered with protective materials, it can easily cause burns to personnel or heat loss. The Haotian high-temperature sleeve has better thermal stability than other polymer materials, as well as resistance to radiation and insulation effects, preventing accidents, reducing energy consumption, and preventing the heat of the medium within the pipeline from directly transferring to the surrounding environment, which can lead to excessively high workshop temperatures, thus saving cooling costs. 
　5.Moisture-proof, oil-proof, weather aging-resistant, pollution-resistant, extending equipment lifespan
　　The high-temperature sleeve has strong chemical stability, as the organic silicone does not react with oil, water, acid, or alkali substances. It can be used long-term without aging at temperatures below 260℃, with a lifespan of several decades in natural environments, greatly protecting the pipelines, cables, and equipment in these situations, significantly extending their service life. 
　6.Ozone-resistant, voltage-resistant, arc-resistant, corona-resistant properties
　　Because the surface is coated with organic silicone rubber, with a main chain of -Si－O－, bonds exist, making it resistant to decomposition by ultraviolet light and ozone. The high-temperature sleeve has excellent electrical insulation properties; its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity are among the best in insulation materials, and their electrical performance is minimally affected by temperature and frequency. Therefore, they are stable electrical insulating materials widely used in the electronics and electrical industries.
　7.Flame retardant, reducing the incidence and spread speed 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 extremely heat-resistant glass fiber woven fabric, with the surface silicone rubber containing 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, still protecting the internal pipelines intact for a longer time, providing ample time to rescue data, documents, and other important information.  7 Commonly Used Areas:
