POLYMER COMPOSITION Russian patent published in 2011 - IPC C08L61/10 

FIELD: chemistry.

SUBSTANCE: polymer composition is based on phenol-formaldehyde novalac resin and urotropin and contains wood dust, carbonaceous filler and lubricant. The carbonaceous filler is schungite and the phenol-formaldehyde novalac resin and urotropin are in form of powdered phenol binder with content of free phenol of not more than 1.0 wt % with the following ratio of components in wt %: binder 38.4-43.7; wood dust 3.0-10.2; schungite 45.2-56.6; lubricant 1.0-2.0.

EFFECT: low volume resistivity of the polymer composition and improved strength characteristics.
