Caustic Soda Microprills are produced at our membrane electrolysis plant in Frankfurt and are of the best quality available in the market.

Big advantage of our Caustic Soda Microprills is that all the microprills are of the same size. There is no wide spread of diameter, which is important when it comes to the manufacturing of (cleaning) formulations where proper mixing properties are required and consequently regular and equally shaped particles are demanded.

Nouryon's Caustic Soda Microprills are solid small fused white pearls, color- and odorless and very hygroscopic. These prills are easily soluble in water and dissolve very rapidly to a caustic soda solution releasing a lot of heat; in methanol and ethanol they are well soluble. Caustic Soda Microprills and caustic soda solutions therefore are corrosive to many materials and have to be handled with great care.

Compared to conventional granules or flakes, Nouryon's Caustic Soda Microprills offer significant advantages:

• Excellent free flowing properties
• Low tendency to stick and agglomerate
• Distinguished for air lifting
• Highly resistant to abrasion
• Minimal dust formation
• Well suited for transportation in road tankers, containers and big bags
• Excellently storable in silo installations
• Precise dosage
• Rapidly dissolving in water, methanol and ethanol


Caustic Soda Microprills are used in many different applications, mainly as basic auxiliary in chemical industry, for the production of aluminum, pulp and paper, surfactants like soaps, detergents, and washing powder, and as catalyst for the production of biodiesel.

Other applications are as cleaning and disinfection agent, for degreasing and paint stripping, preparation of construction materials, manufacturing of cellulose and refining of rayon fibers, metal and wood cleaning, regeneration of ion-exchange resins, production of food and beverages, for neutralization purposes, pH-adjustment and treatment of drinking water and industrial water, treatment of waste water, sewage and waste air cleaning.
