Caustic soda, also known as sodium hydroxide, is a versatile inorganic compound that appears as white solid or liquid. It has strong deliquescence, meaning it can easily absorb moisture from the air, and it dissolves quickly in water with a slight exothermic reaction. This compound is highly corrosive, so proper handling is necessary, but its excellent performance makes it an indispensable raw material in many industrial fields, especially paper making, textile manufacturing, mining, oil processing and water treatment.

Specification:
| Composing | Flake/solid 96 | Flake/solid 98 | Flake/pearl 99 |
| NaOH, % | 96 Min | 98 Min | 99 Min |
| Na2CO3, % | 1 Max | 0.5 Max. | 0.4 Max. |
| NaCl, % | 2 Max. | 0.03 Max. | 0.015 Max |
| Fe as Fe203, % | 0.01 Max | 0.005 Max | 0.001 Max |
Among our products, the Premium caustic soda flakes with a minimum purity of 99% is a star product. This high-quality chemical is widely used in industrial cleaning, water treatment, textile processing, and also in the production of soap, detergents and other daily chemical products. Each batch is tested strictly before leaving the factory, ensuring that it meets industrial-grade standards.

As a professional manufacturer with 25 years of experience, we pay attention to every detail that affects your factory's bottom line:
1. Heavy-Duty Moisture-Proof Packaging
Because this chemical is highly hygroscopic, cheap packaging will cause the flakes to absorb moisture during long transit on the sea, turning into a hard rock block. To prevent this bad situation, we pack our products in 25kg waterproof bags (PP woven bags with a thick PE inner liner). Your cargo arrives loose, dry, and ready for use. We also provide 1000kg and 1200kg jumbo big bags for large enterprises.
2. Perfect for Soap and Detergent Factories
For our buyers in Africa and South America making laundry soaps, our 99% min purity ensures a complete saponification reaction. Your soaps will harden perfectly and will not have any bad chemical smell, helping you protect your brand reputation.
3. Rapid Dissolution for Low Energy Waste
Our white, translucent crystalline flakes are very thin, meaning they dissolve instantly in water without leaving any insoluble residues at the bottom of your mixing tanks. This saves your factory electricity and processing time.
