Washed kaolin
1. Performance
This product mainly by igneous rocks, such as rock by natural decomposition from weathering. For the light gray to pale yellow powder, flake hexagonal crystalline particles. Under the ambient temperature is slightly soluble in hydrochloric acid or acetic acid.
2.Features
With good crystallinity, high purity, small particle size, oil absorption amount of moderate, cover the rate of strong, good dispersion of the advantages of easily dispersed in the rubber compound, is easily processed, smooth surface rubber with carbon black and carbon black, when there is favorable at dispersed rubber compound.
3. Use
Applicable to high-grade paint, coating, ink, rubber, plastics, wire and cable and so on.
