Color strength determination

To determine the color strength,

• Pigment concentration of the masterbatch is reduced to 0.2 % by diluting it in HDPE
• It is carried out with 10 parts of titanium dioxide at 1 part of pigment in the formulation
• The blend is compounded with minimum shear on a two-roll mill or using a single screw extruder
• Color strength is measured at plates of 2 mm thickness
• For color measurements Datacolor or Macbeth spectrophotometer is used.
