In specialized chemical processing, liquid blending, and automated dry-mix manufacturing, the physical geometry of solid sodium hydroxide dictates operational efficiency and workplace safety. Our high-purity caustic soda beads (NaOH ≥ 99.0%) are engineered via advanced prilling towers to provide smooth, spherical particles of uniform diameter. Designed to overcome the bridging, caking, and dust hazards associated with traditional flakes, these free-flowing spherical pearls offer unmatched handling characteristics for precision industrial applications across global markets.
The manufacturing of high-spec spherical sodium hydroxide relies on continuous spray prilling technology. Molten, high-purity sodium hydroxide derived from ion-exchange membrane cells is atomized under controlled thermal gradients, allowing surface tension to form smooth, uniform micro-spheres before solidification.
This precise process yields caustic soda beads with an optimized particle size distribution (typically 0.7 mm to 1.1 mm) and a high bulk density (approx. 1.15 to 1.25 g/cm³). The smooth surface area reduces particle friction, enabling seamless pneumatic conveying and automated hopper discharge without clogging or arching. Crucially, the structural integrity of these hard spheres prevents particle degradation during bulk handling, significantly reducing airborne corrosive dust, enhancing operator safety, and minimizing atmospheric moisture absorption during hopper loading.

1. Optimized solubility: The uniform spherical shape offers large contact area, dissolve completely 40% faster than traditional flakes, saving huge mixing energy.
2. Better process control: Uniform particle size makes precise dosing and stable chemical reaction very easy to control in your automated production line.
3. Efficient supply chain: Our heavy-duty 25kg bags are strong for stacking, which can save much warehouse space and protect against moisture during long ocean shipping.
4. Global compliance: Our factory meets EU REACH standards, ISO 9001 and many international industrial standards. With an annual production of 120,000 tons, we ensure steady and reliable supply of high-purity alkaline pearls for worldwide partners without any shipping delay. Understanding the factory-direct prix de la soude caustique allows distributors to plan their local market retail pricing with confidence.


Classified as a UN 1823 Class 8 corrosive solid (Packing Group II), spherical sodium hydroxide requires strict atmospheric moisture isolation. Product is packed in heavy-duty 25 kg multi-layer PE/PP bags with inner thermo-sealed liners, or 1,000 kg UV-protected bulk bags (Big Bags) equipped with discharge spouts for automated emptying.
Pallets are robotically stretch-wrapped and strapped to ensure structural integrity during ocean freight. Material should be stored in dry, cool, well-ventilated dedicated chemical warehouses away from moisture and reactive acids. Operating personnel must wear full Personal Protective Equipment (PPE), including chemical-resistant nitrile gloves, safety goggles, and protective aprons. When dissolving spherical particles in liquid tanks, always add the compound slowly to water under continuous mechanical agitation to manage exothermic heat generation safely.
