Manufacturer direct sales of Haotian brand thermal insulation sleeves

Manufacturing process: thermal insulation sleeves are woven from special alkali-free glass fiber and carbon fiber yarn, then coated with silicone resin and subjected to high-temperature treatment.
Product performance: It has flame retardant, thermal insulation, heat preservation, electrical resistance, and flexibility properties.
Application range: Mainly used for insulating protection of cable hoses in high-temperature places such as steel mills, smelting plants, and glass factories.
Basic performance (technical parameters)::
Temperature resistance: –60℃＋560℃, continuous working temperature 560℃, can withstand up to 1650℃ in an instant (within 30 seconds), and a destructive test at 1650℃ can last for half an hour. After half an hour, the outer coating begins to carbonize, while the glass fiber remains intact.
Flame retardant: VW-1
Color: Mainly rust red, other colors can be customized as required.
Specifications: Inner diameter 6.5mm-130 mm, sizes above 130mm can be customized as required.

thermal insulation sleeves Features and Applications
1. thermal insulation sleeves provide safety protection, safeguarding workers' health
Alkali-free glass fiber itself has strong tensile strength, does not wrinkle or break, is resistant to vulcanization, produces no smoke, 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 performance is further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose great harm to human health and the environment.
2. thermal insulation sleeves have superior performance
thermal insulation sleeves have a surface organic silicone structure that contains both 'organic groups' and 'inorganic structures'. This special composition and molecular structure allows it to combine the characteristics 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 the C-C bond is 82.6 kcal/mol, while the bond energy of the Si-O bond in organosilicon is 121 kcal/mol, resulting in high thermal stability. The chemical bonds of the molecules do not break or decompose at high temperatures (or under radiation exposure). Organosilicon can not only withstand high temperatures but also low temperatures, allowing it to be used over a wide temperature range. Whether in terms of chemical properties or physical mechanical properties, the variations with temperature are minimal.
3. thermal insulation sleeves are moisture-resistant, oil-resistant, climate aging-resistant, pollution-resistant, and extend the service life of equipment
thermal insulation sleeves have strong chemical stability, and organosilicon does not react with oils, acids, bases, etc. Within 550℃, it can be used for a long time without aging, and its lifespan in a natural environment can reach several decades, maximizing protection of pipes, cables, and equipment in these environments, significantly extending their service life.
4. thermal insulation sleeves are ozone-resistant, voltage-resistant, arc-resistant, and corona-resistant
Due to the surface coating of organic silicone, which has a main chain of –Si-O-, the bonds are not easily decomposed by ultraviolet light and ozone. Haotian brand fire-resistant sleeves have excellent electrical insulation performance, with dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity among the best in insulation materials, and 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.
