Caustic soda pearls are granular, low in dust, free-flowing and suitable for automated lines. Compared with flakes, they reduce labor costs, improve feeding accuracy and create a cleaner working environment. Our 99% high-purity pearls are widely used in fine chemicals, pharmaceuticals, water treatment and metallurgy.
Our 99% caustic soda pearls cover a wide range of industrial and specialized applications, perfectly matching the demands of modern production and precision processes.
Industrial Fields
Fine Chemical Manufacturing: Low-dust, high-purity pearls for precision chemical manufacturing requiring consistent quality and low impurity levels.
Water Treatment: Free-flowing, non-caking pearls ideal for automated dry chemical feeders in UK and European water treatment works. Full COA and SDS provided.
Metallurgy & Mineral Processing: A key raw material in mining and metallurgy, especially in South Africa. Used for flotation agent preparation, gold cyanidation leaching and mineral processing wastewater treatment. The uniform particle size ensures consistent dissolving speed and reaction efficiency.
Automated Textile Lines: Clog-free, consistent dosing for advanced UK and European mercerising and scouring systems.
Fine Chemical Production: Uniform dissolution rates ensuring batch-to-batch consistency in European synthesis processes.
Specialized Fields
Food Industry CIP: High-purity pearls suitable for clean-in-place (CIP) systems in dairy and brewing facilities.
Electroplating Industry: Used for the preparation of chromium plating and zinc plating solutions. Also applied in workpiece pretreatment for degreasing and oxide layer removal, ensuring clean and uniform plating quality.
