White masterbatch is a type of additive that is used to add whiteness or opacity to plastic products. It is a concentrated mixture of titanium dioxide (TiO2) and a carrier resin, which is typically a thermoplastic polymer like polyethylene (PE), polypropylene (PP), or polystyrene (PS).

The TiO2 pigment in the white masterbatch provides the opacity, brightness, and whiteness to the plastic product. The carrier resin ensures that the masterbatch can be easily incorporated into the base polymer during the manufacturing process, resulting in a uniform color distribution.

White masterbatch is widely used in various industries such as packaging, automotive, construction, and household goods. It is used to produce a range of products such as films, sheets, pipes, bottles, and containers.

The concentration of TiO2 in the white masterbatch can vary from 20% up to 80%, depending on the desired level of opacity and color intensity. The masterbatch can also contain other additives such as stabilizers and process aids, which improve the performance and processability of the product.
