China High Quality Iron Oxide Red Used for Fade-Resistant Dye for Plastics

Product Description

Iron Oxide Red
Formula: Fe2O3
Molecular Weight: 159.69
CASNo.:1332-37-2
EINECS: 215-570-8
Relative density 5-5.25. Fineness 0.4 ~ 20 um. Melting point 1565(decomposition). When burned, oxygen is released, which can be reduced to iron by hydrogen and beta carbon oxide. Insoluble in water, soluble in hydrochloric acid, sulfuric acid, slightly soluble in nitric acid and yeast. It has excellent light resistance, high temperature resistance, acid resistance, alkali resistance and rust resistance. Good dispersity, strong coloring power and hiding power, no oil permeability and water permeability.
