**Characteristics and Applications of Thermal Insulation Sleeves** - Weather aging resistance, pollution resistance, extend the service life of equipment. The service life in natural environments can reach several decades, maximizing the protection of pipes, cables, and equipment in these situations, significantly extending their service life. - Ozone resistance, voltage resistance, arc resistance, and corona resistance. Due to the surface coating of silicone rubber, whose main chain is -Si-O-, the bonds present make it difficult to be decomposed by ultraviolet light and ozone. High-temperature protective sleeves have excellent electrical insulation properties, ranking among the best in dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity among insulating materials. Moreover, their electrical performance is minimally affected by temperature and frequency. Therefore, they are a stable electrical insulation material widely used in the electronics and electrical industries. - Superior high-temperature resistance. High-temperature protective sleeves can withstand continuous exposure to temperatures of 260°C without damage, endure high temperatures of up to 1090°C for 15 to 20 minutes, and withstand temperatures of 1650°C for 15 to 30 seconds. Their unique flame-retardant properties not only effectively prevent personnel from being burned by high-temperature pipelines but also significantly reduce costs associated with thermal energy loss. - Unique chemical stability. High-temperature protective sleeves exhibit strong chemical stability, showing no reaction to oil, water, acids, and alkalis in organic silicone, and can be used long-term without aging at temperatures below 260°C. Because of the surface coating of silicone, they are not easily decomposed by ultraviolet light and ozone. - Splash-proof, multi-layer protection. In the smelting industry, the medium temperature inside electric furnaces is extremely high, making high-temperature splashes easy (the same applies to the electric welding industry). After cooling and solidifying, they form slag on pipes or cables, which can harden the rubber outer layer and eventually lead to brittleness and cracking. This damages unprotected equipment and cables. The high-temperature sleeves with multiple layers of silicone coating provide multi-layer safety protection, with high-temperature resistance up to 1300°C, effectively blocking splashes of molten iron, copper, aluminum, and other high-temperature molten materials to prevent damage to surrounding cables and equipment. - Safe and environmentally friendly. Alkali-free glass fiber itself has strong tensile strength, is wrinkle-resistant, sulfur-resistant, smoke-free, halogen-free, non-toxic, pure oxygen non-flammable, and has good insulation properties. After being cured with silicone rubber, its safety and environmental performance are further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose significant harm to human health and the environment.
