Caustic soda flakes
| Purity ( W/W%) | 98 |
|---|---|
| Application(s): | Pulp and paper industry , Oil and gas industry , Pharmaceutical industry |
Description
Caustic soda flakes (sodium hydroxide flakes) are solid white flakes that are hygroscopic and highly soluble in water. These flakes are produced by evaporating high-quality liquid caustic soda, which is manufactured using membrane technology. The result is a high-purity sodium hydroxide solid suitable for a wide range of industrial applications.
Applications of Caustic Soda Flakes
This NaOH 98% solid is widely used in:
- Acid neutralization processes
- Manufacturing of soaps and detergents
- Pulp and paper industry
- Oil and gas processing
- Pharmaceutical production
- Aluminum refining and surface treatment
Its chemical stability and purity make it ideal for sectors requiring industrial-grade caustic soda.
