Note: 
1. When temperature is above 400 centigrade, the product must be used in protective atmosphere or inert gas. 
2. It can be cut free geometrical shape. 
USE: 
1. For thermal insulation: Vacuum resistance furnace, induction furnace, Sintering furnace, etc. 
2. For electrical conductive: Porous electrodes, etc. 
3. For heating materials: Carbon fiber crystal heating tube.
