Haotian Brand Fireproof and Flame-retardant Insulation Sleeve Features and Applications

1. Safe and environmentally friendly, protecting workers' health
　　Alkali-free glass fiber itself has extremely high tensile strength, does not wrinkle or break, is resistant to vulcanization, produces no smoke, halogen, or toxic substances, is pure oxygen non-combustible, and has good insulation properties. After being cured with organic silicone, its safety and environmental performance are further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose great hazards to human health and the environment.
　2. Excellent high-temperature resistance
　　The surface of the high-temperature sleeve has an organic silicone structure containing both 'organic groups' and 'inorganic structure'. This special composition and molecular structure combine the characteristics of organic substances with the functions of inorganic substances. Compared with other polymer materials, its outstanding feature is high-temperature resistance. With a Si-O (Si－O) bond as the main chain structure, the bond energy of C-C bonds is 82.6 kcal/mol, while the bond energy of Si-O bonds in organosilicon is 121 kcal/mol, which gives it high thermal stability. Under high temperatures (or radiation exposure), the chemical bonds of the molecules do not break or decompose. Organosilicon can withstand high temperatures and is also resistant to low temperatures, allowing it to be used over a wide temperature range. Both its chemical properties and physical mechanical properties change very little with temperature variations. 
　3. Splash-proof, multiple protections
　　In the metallurgy industry, the medium temperature inside electric furnaces is extremely high, making it easy to form high-temperature splashes (the same applies to the welding industry). When cooled and solidified, they form slag on pipes or cables, which can cause the rubber outer layer of the pipes or cables to harden and eventually become brittle and break. This can damage unprotected equipment and cables. The high-temperature sleeve coated with multiple layers of silicone can provide multiple safety protections, with high-temperature resistance reaching up to 1300 degrees Celsius, effectively blocking the splashing of molten iron, molten copper, molten aluminum, and other high-temperature molten materials, preventing damage to surrounding cables and equipment.
　4. Insulation and heat preservation, energy saving and consumption reduction, radiation resistance
　　In high-temperature workshops, many pipes, valves, or equipment have very high internal temperatures. Without protective materials, it is easy to cause burns to personnel or heat loss. Haotian's high-temperature sleeve has better thermal stability than other polymer materials and also provides radiation protection and heat insulation, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipes from directly transferring to the surrounding environment, which can lead to excessively high workshop temperatures, thus saving cooling costs. 
　5. Moisture-proof, oil-proof, climate aging resistance, pollution resistance, prolonging equipment lifespan
　　The high-temperature sleeve has strong chemical stability, with organosilicon being unreactive to oil, water, acids, and bases. It can be used long-term without aging at temperatures up to 260℃, and under natural conditions, its lifespan can reach several decades, providing maximum protection for pipes, cables, and equipment in such environments and greatly extending their lifespan. 
　6. Ozone resistance, voltage resistance, arc resistance, corona resistance
　　Because the surface is coated with organic silicone, which has a main chain of -Si－O－, the bonds are not easily decomposed by ultraviolet light and ozone. The high-temperature sleeve has excellent electrical insulation properties, ranking high in dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity among insulating materials, and their electrical performance is little 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 rate of fires
　　If the medium transported in the pipes is flammable or toxic, leaks can easily lead to fires or casualties; cables often catch fire due to localized high temperatures. The high-temperature sleeve is made from extremely heat-resistant woven glass fiber, with surface silicone containing appropriate flame retardants and other special 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 piping intact for a longer period, providing ample time for the rescue of data and important information.
