Fireproof sleeving—also known as high-temperature resistant sleeving, or silicone-coated fiberglass sleeving—is manufactured by weaving alkali-free fiberglass into a tubular form, which is then coated on its outer surface with organic silicone rubber and subjected to a vulcanization process. Once vulcanized, the sleeving can be utilized for extended periods within a temperature range of -65°C to 300°C while retaining its inherent softness and elasticity. It is generally well-suited for protecting relatively short or straight pipelines and cables. Commonly employed for cable protection and in automotive wiring harnesses and generator sets, it also finds extensive application in high-temperature and heating zones across various industries—including steel manufacturing, smelting, shipbuilding, and chemical processing—as well as for fluid lines, rolling mill cables, oil pipes, cables in sawing and edging equipment, electrical voltage apparatus, large-scale construction projects, hydraulic systems, and automotive exhaust systems. The composition of these specialized high-temperature resistant materials endows this fireproof sleeving with a host of characteristics that are difficult for other similar materials to replicate: exceptional resistance to high temperatures, superior thermal insulation properties, flame retardancy, electrical insulation capabilities, chemical stability, resistance to weathering and aging, as well as resistance to cold, water, oil, ozone, high voltage, electrical arcs, and corona discharge.

The wrap-around (hook-and-loop) high-temperature fire-resistant sleeve is designed for on-site installation. Its key advantages include ease of assembly and disassembly without the need to shut down equipment or disconnect cables and hoses. Featuring an internally stitched, fire-resistant hook-and-loop fastener, it provides a secure seal and insulation simply by pressing the edges together; this ensures production continuity while saving installation time. It is commonly used for large smelting equipment and flexible metal hoses, ensuring a tight seal and structural integrity. The fastening mechanism allows for size adjustment to ensure a snug fit. Widely used in industries such as metallurgy, chemicals, power generation, forging, automotive, petroleum, defense, and shipbuilding to encase cables, hoses, oil lines, and more. Key Advantages Flexible, wear-resistant, and resistant to water and oil. Cables and pipelines in high-temperature areas of metallurgical plants typically require protective high-temperature sleeving. However, for active production lines or hard-to-access components—such as rolling mill cables that are difficult to detach—traditional tubular sleeves are often inconvenient to use. To address this, we developed a detachable high-temperature sleeve. It can be wrapped around cables or pipes and sealed with the hook-and-loop fastener, effectively protecting equipment that is currently in operation or difficult to disassemble. Also known as wrap-around or split-type high-temperature sleeves, these products offer the advantage of on-site installation without requiring equipment shutdowns or the disconnection of hoses and cables. They ensure a proper seal and structural integrity. Constructed from high-temperature fiberglass with an internally stitched, fire-resistant hook-and-loop fastener, the sleeve provides insulation and sealing; once adjusted to the correct size, the fastener secures the sleeve tightly in place. Temperature Resistance Specifications This detachable high-temperature sleeve provides reliable protection at 550°C against heat radiation and can withstand short-term exposure to molten steel at temperatures up to 1100°C. Scope of Application for Removable High-Temperature Sleeves High-temperature areas in the electric power, chemical, and other industries; Applications in metallurgical enterprises, including: cables and fluid lines in heating zones; quick-connect couplings for feed systems; roller tables and cables in rolling zones; oil lines; cables, oil lines, and fittings around sawing equipment; and protective coverings for ladle car cables.

Product Description:High-silica self-adhesive tape is an inorganic, fire-resistant wrapping tape featuring a high-silica fiberglass substrate (SiO₂ content ≥95%) coated on one side with a high-temperature-resistant pressure-sensitive adhesive. It is **not** a silicone rubber self-adhesive tape. Its key characteristics include long-term temperature resistance of 1000–1300°C (with short-term peaks exceeding 1600°C), non-melting/non-dripping behavior, non-flammability, and self-extinguishing properties. Upon wrapping, it achieves "self-setting" (bonding via the fiber structure) rather than "self-fusing" (material amalgamation) when exposed to high temperatures. Main Composition and Structure: High-purity high-silica fiber (SiO₂ ≥95%); not silicone rubber. The adhesive backing is typically silicone-based or ceramic-forming pressure-sensitive adhesive; it carbonizes and decomposes at high temperatures (>300–500°C), allowing the fiber itself to wrap tightly around the object and form a mechanical protective layer.Temperature Resistance Range: Long-term use at 800–1000°C; instantaneous resistance up to 1300–1600°C (far exceeding the –50°C to 260°C range of silicone rubber self-adhesive tapes). It maintains electrical insulation properties at high temperatures but does **not** exhibit self-fusing adhesion at room temperature (unlike the "self-fusing" nature of silicone rubber tapes). Application Scenarios:Thermal insulation wrapping for high-temperature piping (e.g., exhaust pipes, turbocharger lines); binding and securing of motor and transformer coils; cable protection near furnaces in the metallurgy and foundry industries; fire-resistant sealing; thermal protection layers for aerospace and military applications; and flame-retardant wrapping for high-temperature areas in marine and rail transport.
