Significantly lower production costs for higher profitability
Calcium sulfate with a very high level of purity can partially substitute titanium dioxide as a white colorant. Proof of this application advantage are tests carried out with different types of plastic that show optimal whitening effects without impact on functional properties.
TOROWHITE calcium sulfate of the highest whiteness extends TiO2 in white color masterbatches. In addition a multitude of pastel colors could be also achieved by its addition.
Its high purity, resistance to weak acids and good stability at high temperature, its particle shape and size as well as its narrow particle size distribution and the potential for cost savings it offers, make it an excellent extender in polymers.
Excellent whiteness (L-value >96)
Very good results in terms of brightness and opacity
Increases machine longevity and reduces tool wear due to its low Mohs hardness
