EFFECT OF DOLOMITE POWDER ON COMBUSTION AND TECHNOLOGICAL PROPERTIES OF WPC AND NEAT POLYPROPYLENE

ABSTRACT Water resistance, mechanical properties, and limiting oxygen index (LOI) of wood plastic composites (WPCs) and neat polypropylene filled with different amounts (3, 6, and 9% by weight) of dolomite powder and wood flour (15 and 30 by weight) were investigated. Wood flour, dolomite powder, po...
