How to choose white masterbatch by coverage and cost
Choosing white by coverage, appearance, and practical cost instead of random overuse.
Choosing white masterbatch is not only a matter of color; the requirement is usually consistent white coverage and a clean look at a reasonable cost. When coverage is weak, the base material color shows through the white, and the answer is not always to increase the quantity.
Factors like product thickness, base material color, and process affect the white grade needed. A thin product needs higher coverage than a thick one, and a darker base material needs more effort to cover.
White masterbatch is available in different loadings to balance coverage and cost by application. Choosing the higher grade is not always necessary; sometimes a lower grade is enough when the selection is right.
Random overuse raises cost and may not fully solve the problem. The correct comparison is on the coloring cost per unit of product and the final result, not the price per kilogram of masterbatch alone.
The best approach is to test the grade on the same product and thickness and see the real coverage before committing to a large quantity.
