Eka® SC (sodium chlorate) is essential to environmentally compatible paper pulp bleaching. It is the functional ingredient in the generation of chlorine dioxide, which, in turn, is the main component in ECF (Elemental Chlorine-Free) bleaching. Up to 95 percent of all sodium chlorate produced worldwide is consumed by the pulp industry. Its second most common use is by the chemical industry where it is used as a precursor in the production of sodium and ammonium perchlorate and sodium chlorite. Sodium chlorate and sodium chlorite are the common precursors to chlorine dioxide, which is used in many water treatment applications. Other common industrial applications for sodium chlorate include as an oxidant in the mining industry for the extraction of uranium and vanadium; in the automotive industry as a surface treatment for metals; it is also used in the Printed Circuit Board industry for the control and replenishment of the cupric chloride etchant. This versatile chemical is utilized in many devices that require an oxygen source (e.g. breathing apparatus).

Safety & Health
- Safety and Handling Information
Eka® SC is classified as dangerous goods. It is a strong oxidizing agent and is very soluble in water. Crystal sodium chlorate is stable at temperatures up to 250°C (482°F). Above this temperature chlorate decomposes and oxygen is liberated. Be aware that sodium chlorate in liquid form is a hazard as well. Sodium chlorate solution is a clear odorless liquid that may become invisible when it dries on any organic material like cloth, leather, paper or wood. All that is required is a spark, minor friction or heat, to ignite. Sodium chlorate in its pure form is not flammable; however, due to the fact it releases oxygen during decomposition, it will act as an extreme combustion accelerant in the presence of flammable materials.
Packaging & Availability
- Packaging Type
- Packaging Information
Depending on the customer set-up, Eka® SC is shipped in bulk tank, drums or in supersacks. Eka® SC is classified as hazardous material and consequently transportation and packaging design must adhere to the all applicable transportation regulations. Transportation may take place by road, railway, air or sea. Each mode of transport demands specific regulations with special requirements regarding packaging, vehicle and documentation.
