Emulsified Sulphur
Chemtrade manufactures a flowable, micronized sulphur emulsion suspended in water called Sulex 70, which is used in pulp and paper applications as a cost-effective sulphidity builder. It is also used in agricultural applications as a slow release sulphur fertilizer and as an effective soil amendment to modify alkaline soils.
Sulphur, in various forms, is also important in EV Battery production. For more information, visit our EV Battery chemicals page.
Chemtrade’s Sulex 70 is manufactured at our Mount Vernon, Washington facility and is available in bulk, truckload quantities for shipment throughout the Pacific Northwest and Western Canada.
