Product characteristics
In the solid base, the flake caustic soda and the granular caustic soda are the most common and used of a solid base, and the particle caustic soda is better than the flake caustic soda, but the production process is more difficult and more complex than the flake caustic soda, so the price of the caustic soda is naturally higher than the flake caustic soda.
