Reliable Caustic Soda Company with Bulk Supply and Global Delivery

Product Description:

Key Product Features – Pearl Caustic Soda

Our pearl caustic soda (CAS 1310-73-2) is a premium solid alkali that appears as translucent white granules, with particle sizes between 0.5 mm and 2.0 mm. It has a density of 2.130 g/cm³ and melting point at 318.4°C, making it ideal for heavy-duty industrial use. The biggest advantage is its unique granular shape: unlike flake types, these pearls dissolve much more evenly, prevent local overheating and splashing, and flow smoothly for accurate dosing with automated systems. This cuts down human error and material waste a lot.

Produced with advanced ion-exchange membrane technology, our high-purity grade reaches over 99.9% purity, with harmful impurities like mercury and arsenic below 0.001%. It meets not only general industrial standards but also strict requirements for fine chemicals and pharmaceuticals. Though it absorbs moisture similar to flakes, its particle structure improves storage stability by over 15% when properly sealed. As a trusted caustic soda company, we ensure every batch is carefully tested before shipping.

We offer standard packaging in 25kg bags with PE inner liners and woven polypropylene outer bags, plus 1000kg jumbo bags with lifting loops for easy handling. Custom logo printing and warning labels are available upon request. Logistics include full 30-ton truck loads and less-than-truckload options, with fast delivery across many regions.
