Physical & Chemical Characteristics

A kind of hypo-white powder, which is odorless, tasteless and non-poisonous, the product has a bulk density of 0.7~1.1g/ml. Having dispersivity, the product feels greasy. It is insoluble to water, organic solvent, and various oils & lipids.

Applications & Rang of Use

1. In refinement of animal & vegetable oils, used for decolorization and purification to eliminate harmful pigments, flavacol, phospholipid, saponin, gelatine, and cotton acid etc. in the oil, rendering it into top-grade cooking oil.
2. For decolorization & refinement of industry-used animal & vegetable oils.
3. In petroleum industry, used for decolorization, refinement and purification of petroleum, grease paraffin, white oil, lubricating oil, Vaseline, and kerosene etc.
4. For recycling and regeneration of industrial waste oils (including mineral oil, such as machinery oil and lubricating oil etc.)
5. For decolorization & depuration of resin.
6. For decolorization & depuration of polyether.
7. In food industry, used as clarificant for monosodium glutamate vitamin, grape wine, candy juicy, used for stabilizing treatment of beer, and used for purification of sugar juices.
8. For alkene separation in arene and alkane, cracking of petroleum and alkene polymerization catalyzed.
