SFT1500 series is a high-temperature fire-proof tube constructed from an alkali-free fiberglass braid coated with iron-oxide red silicone rubber. It offers enhanced thickness than conventional insulation sleeves and can withstand short-term thermal shock up to approximately 1650℃. The fire-proof tube delivers outstanding performance in fire resistance, flame retardancy, thermal insulation, electrical insulation, resistance to acids and alkalis, and aging resistance.
Applications
This fire-proof tube is widely used for pipeline and cable protection in high-temperature environments such as steel plants, smelters, glass factories, rail transit systems, and large transformers. It is also suitable for protecting new energy battery pack harnesses and busbars.
