The Evaluation of Dispersing Additives Performance is Based on Color Strength 1. Color strength of a masterbatch with known pigment concentration and standard dispersant PP wax is measured and set to 100 2. PP wax is replaced by our dispersant and color strength is measured 3. Reduction of pigment & dispersant concentration at constant ratio (e.g. 2:1), parts to 100 filled with base polymer 4. Color strength of each masterbatch is measured and formulation with color strength 100 is identified 5. Cost of original and new formulation with color strength 100 are calculated and compared (see next slides) Calculation directly shows which benefit our customers can expect
