Suggestions for Compounding Colored Rubber

Compound to conserve color cost

The color is usually the most expensive ingredient in a compound. It is often sensitive to curing conditions and to other compounding ingredients. Anything which tends to change the shade of the base compound will affect the color shade.

Compound with the correct grade of rubber

Where crude rubber is used, the darker and cheaper grades should be used only in deep shades. Use light colored rubbers for pastel shades. Use non-staining synthetic rubbers.
Compound with non-discoloring accelerators, antioxidants and plasticizers.

Compound for proper cures

Temperatures above 320℉ are risky with many organic colors, particularly in light shades. Select colors carefully for higher temperatures. See the properties sheet for Akrochem Selected Rubber Colors.

General Notes:

  1. Cool stocks before stacking to prevent change in shade.
  2. Do not use dark colored fillers.
  3. Titanium Dioxide and Zinc Oxide improve brightness in pastel shades.
  4. Reduce the use of Titanium Dioxide to a minimum for deep shades.
  5. Excessive use of fatty acid or softeners may cause mold staining, color streaking or
    blooming of the color.
