Ceramic fiber module

Product description:
RACOFIBER™ ceramic fiber module is made by folding and compressing the high quality double needled ceramic fiber blanket ,then install the anchoring accessories to bundle them tight together .

Features:
Low density ,low heat capacity, extremely speed up the heating and cooling time of the kiln
Low heat conductivity, efficiently saving the energy.
Good performance of heat shock resistance
Airflow shock resistance
Good mechanical capacity
Easy to be installed and used
