The above values are average values  and they do not constitute a specification.

DBU - standard quality  carbon blocks  ;
DBU-A
- carbon blocks with higher  thermal conductivity;
DBU-B
- carbon blocks with  higher strength characteristics;
DBU-A (
М) - carbon blocks with higher thermal conductivity  and strength characteristics;

DBPM - micropore carbon blocks.
