Functional fillers have become indispensable in the manufacture of many plastics. The most important plastics application for calcium carbonate continues to be polyvinyl chloride (PVC). SCHAEFER PRECARB®'s special crystal structure, particle fineness and particle size distribution make it easy to disperse in the polymer matrix without any surface treatment at all, even at higher filler levels. SCHAEFER PRECARB® thereby contributes to cost reduction without any compromise in quality.
Calcium stearates, salts of stearic acid or also called lime soaps, are used, among other things, for the production of stabilizers for plastics. Other applications are: As lubricants for pharmaceutical products, as lubricants in the paper and metal processing industry and as a water repellent for building materials. SCHAEFER PRECAL 54 and SCHAEFER PRECAL 56 are preferred for the production of calcium stearates due to their chemical purity, reactivity and particle fineness.
