PRODUCT OVERVIEW

Product Description

CSP Series Caustic Soda Pearls is a high-purity sodium hydroxide product supplied in white pearl form. Sodium hydroxide is a strong alkaline inorganic compound widely used in industrial processing. The pearl form provides a solid commercial grade suitable for applications including soap and detergent powder, paper making, fiberglass, oil refining, and water treatment. The product is hygroscopic and can absorb moisture and carbon dioxide from the surrounding air, so its physical quality depends on appropriate sealed storage conditions.
