Description：
● Huolong Ceramic Fiber Blanket was adopted continuous processing method，the fiber interweaved shapely after being needled，which of excellent tensile strength. The blanket contains not any bonding agent 。
● Our needled blanket has various density and thickness so that our client can have many choices, which will bring the perfect insulating framework and profit.
● Huolong Ceramic Fiber Blanket can resist the chemical species well, but not the Hydrofluoric Acid, Phosphoric Acid and Strong Base.
● Huolong Ceramic Fiber Blanket have excellent capability of resisting the oil, after being dried it will repossess the thermal characteristic and the physical feature.

Characteristic： ● Excellent Chemical Stability ● Excellent Thermal Stability ● Excellent Tensile Strength ● Low Thermal Conductivity ● Low Heat Storage
