Which is the better fireproof effect, aluminum silicate cotton fireproof sheath or silicone rubber fireproof sheath?

Aluminum silicate wool fireproof sheath and silicone rubber fireproof sheath. Aluminum silicate wool is a kind of fireproof material made of aluminum silicate fiber, which has good fire resistance, heat insulation and high temperature resistance. It is usually used for heat preservation and fire prevention of high-temperature equipment such as boilers, kilns and high-temperature pipelines. Silicone rubber is a kind of polymer material, which has good high temperature resistance, corrosion resistance and aging resistance. Usually used to make seals, insulating materials, high-temperature gloves, etc. Therefore, in terms of fire prevention, both aluminum silicate cotton and silicone rubber have good fire prevention performance.
