The high silica oxide sleeve is made of high silica oxide fibers and possesses excellent properties such as smoothness, softness, high temperature resistance, fire resistance, personal protection, and insulation. It can operate continuously at a temperature of 1000°C. It is an essential protective product for pipes like hoses, oil pipes, and cables in ultra-high temperature and open flame situations.
The high silica oxide sleeve is suitable for metal melt filtration and purification, high-temperature gas dust collection, liquid filtration, high-temperature burning materials, welding insulation protection materials, automotive and motorcycle noise reduction, heat insulation, and exhaust gas filtration, etc. It can be surface-coated according to user requirements.
