Classification by refractoriness:
Ceramic fiber blanket, also known as aluminum silicate fiber blanket. Ceramic Fiber Board is made by special forming process. Ceramic fiber blanket is with white color, standard sizes, thermal insulation and high temperature resistance function. Its working temperature ranges from 950℃~1400℃.
SIJIHUO Refractory provides ceramic fiber board of high temperature 1260℃(2300℉), (1426℃)2600℉. Ceramic fiber boards are available in various of high temperature ratings, sizes, and customized shapes.
