Titanium Dioxide Application
This titanium dioxide of general-purpose is one of the main products of our company. This product is wet-milled by imported sand mill, with good particle size distribution; The surface is treated with a dense inorganic coating of silica and alumina, which has superior pigment performance.
It is used for plastics articles like PVC pipeline, coating, papermaking, ink, master batch, etc.
Main Features
1) Good whiteness and gloss;
2) Excellent color reduction and hiding power;
3) Better resistance for weather, heat and light;
4) Broad application.
