Optical brightener masterbatch

The whitening masterbatch is a plastic masterbatch composed of titanium dioxide, fluorescent whitening agent, dispersant, antioxidant, anti-aging agent, etc. Because the use of recycled materials in plastic production often leads to a grayish tint in the finished plastic products, and directly adding whitening agents often leads to uneven coloration due to inadequate mixing, this masterbatch has been developed to address the issue. By using this masterbatch, the whiteness of product can be significantly enhanced, resulting in a thicker, fuller appearance with a more uniform color. Consequently, it serves the dual purpose of increasing the usage of recycled materials and lowering production costs.

Product performance

High whiteness, high covering, uniform dispersion, and strong tinting strength.

Application field

Applied in film blowing, injection molding, etc.
