Plastics | PVC

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 are used in the production of so-called non-tox stabilizers of plastics, preferably in combination with zinc stearate, or alternatively with barium stearate or magnesium stearate.  SCHAEFER PRECAL® products are the preferred choice in the production of calcium stearates due to their chemical purity, reactivity and particle fineness.

Applications

Applications

PCC product applications

  • PVC window profiles / frames
    With its specially tuned properties, SCHAEFER PRECARB® contributes significantly to the improvement of optical properties such as whiteness, gloss and surface finish, mechanical properties such as notched impact strength, and to the weathering durability of PVC window profiles. As a result, window frames require less frequent cleaning, have a longer service life and retain their high-quality appearance over the long term.

Lime product applications

  • Calcium stearate
    Calcium stearates are used in the production of so-called non-tox stabilizers of plastics, preferably in combination with zinc stearate, or alternatively with barium stearate or magnesium stearate. They also serve as lubricants in pharmaceutical products, as lubricants in the paper and metal processing industries, and as water repellents for building materials.
