The first step in product selection is determining the physical characteristics you want to impart to an end product. For example: increase or reduce weight; increase strength, flexibility or rigidity; add absorption characteristics; or introduce non-slip / anti-skid texture. The next step is to quantify the sought after attributes in the Filler or Extender, including particle shape or size; hardness; specific gravity; absorbency; reactive or inert; and temperature.
