What is the descriptions of ceramic fiber blanket ?
1.Ceramic fiber blanket is made of high quality alumina-silicate ceramic fiber by using double side needling methods which improve the tensile strength and the flatness of the ceramic fiber blanket.
2.Ceramic fiber blanket contains no organic binders which guarantee the stability and constructability of the ceramic fiber blanket at both high temperature and low temperature.
