Titanium Dioxide

In order to satisfy requirements of different customers, we can provide internally piloting index of distribution of sizes , specific surface area, dispersancy, chromatic aberratio, iron content, microelement etc. Packed in bag with net weight of 25kg, or additionally with a plastic-weaved, paper plastic or paper bag. There are two package methods for them,sewed package and poured package for the customers' requests.

Quality standard

The standard for the products sold in domestic market is GB1706-93, while ISO787 or GB1706-93 is for the products sold in abroad market.
