White masterbatch is one of the most widely used mixtures in the polymer industry. White masterbatch is a mixture of base polymer with white pigment and additive, which is added to polymer products to create white coating and color.
An essential additive in the production of white masterbatch is titanium dioxide, which creates desirable final properties due to its high refractive index, good dispersion in the matrix, and chemical and thermal stability. Calcium carbonate, zinc sulfate, barium sulfate, talc, etc., are other standard white pigments that each have a specific use according to their properties.
Our white masterbatches contain high-quality titanium dioxide. Each product’s type of titanium dioxide is selected to match the intended indoor and outdoor applications’ requirements.
Our White masterbatches are processed in state-of-the-art compounding lines, and each lot is subjected to a series of tests based on international standards. We have set strict tolerance limits for each parameter, studying the requirements for each end-use.
Parameters controlled are pigment content, color, dispersion quality, moisture content, and pellet size and quality.

Available white masterbatches include three categories, Rafcolor, Filcolor, and Colorin, and each class contains four grades.
