ceramic fiber blanket

HYWOOL Ceramic Fiber Blanket is a new type of Refractory Insulation material. It is also known as Alumina Silicate Fiber because one of their main components is alumina, which is the main component of porcelain.

HYWOOL Ceramic Fiber Blanket is made of spun aluminum silicate fiber by double-sided needle punching process. After the double-sided needle punching process, the Ceramic Fiber Blanket has excellent delamination resistance, tensile strength and the surface smoothness.

HYWOOL Ceramic Fiber Blanket do not contain any binders to ensure the maintain stability under higher or lower temperature conditions.
