The use of KREIDER’s coated calcium carbonate of MK-90T and MK-60T grades in polyethylene & polypropylene compositions allows obtaining the optimal balance between rigidity and impact resistance of the final product.

High-quality stearic acid treatment makes our GCC fillers as compatible with synthetic and natural polymers as possible.

Narrow particle sizes distribution of MK-90T chalk (d99% – 4µm) provides excellent mechanical properties even in the most highly filled PP and PE compositions.

Natural chalk has a several times higher thermal conductivity and a lower coefficient of expansion, compared to polyolefins. This allows to increase molding speed, accelerate the process of cooling of the finished product and boost the productivity of processing as a whole.
