Features

Buratex B 4001 is a flexible cotton packing impregnated with black grease and graphite to improve the thermal conductivity. When it is manufactured, particularly tear-resistant cotton threads are pre-impregnated and twisted. At the next diagonal braiding step, the packing undergoes an additional intensive impregnating and graphiting stage.
