Plastic

The processing of many plastics today can no longer do without functional filling materials. The most important plastics application for calcium carbonate continues to be in polyvinyl chloride (PVC).

With its specially set properties, SCHAEFER PRECARB significantly contributes to improving optical characteristics such as degree of whiteness, gloss and surface finish, to mechanical strength and also to weathering resistance of PVC window profiles.

Due to its special crystal structure, particle fineness and grain size distribution, SCHAEFER PRECARB is easily dispersed in the polymer matrix without surface treatment, even in the case of higher filler levels. Thus SCHAEFER PRECARB contributes to cost reduction without any loss in quality.
