Requirements on TiO2 Pigments for the MB Industry, 2002 PLACE Conference Proceedings
The outstanding optical properties of titanium dioxide, such as brightness and high tinting strength, make it the most commonly used white pigment in polyolefins, styrene polymers and engineering plastics.
Masterbatches are a suitable and time-proven means for incorporating pigments into polymers in sufficiently dispersed condition.
In order to achieve optimum processability during batching and the subsequent processes, as well as the associated maximum development of the optical properties and stability in the end-product, TiO2 pigments are given special
surface treatment and thus matched to the carrier polymer and the properties required in the ultimate application.
The present paper discusses the influence of various TiO2 pigments on rheological properties, throughput and state of dispersion in masterbatch production, as well as their impact on the optical properties, UV stability and manufacture of the end-product.
