| Grade | Solubility | Function and Application | Remark |
| TC-J18 | Water-soluble | Viscosity reduction of oil, for such as the transportation of oilfield, crude oil. | Polyoxyalkylene |
The main components of TC-J18 crude oil viscosity reducing agent are non-ionic surfactants based on polyoxyalkylene compounds, which are complexed by high molecular weight polymers formed by block polymerization of initiators with propylene epoxide and ethylene oxide. The product is mainly used for reducing the viscosity of crude oil in oilfield extraction. The product is soluble in water and alcohols.
