Are you searching for a reliable source of caustic soda 25kg bags for your industrial operations? Look no further. As a leading chemical manufacturer based in Tianjin, China, we produce and export high-purity caustic soda 25kg products to clients across the globe. From soap factories in Southeast Asia to paper mills in Europe and water treatment plants in the Middle East, our caustic soda 25kg bags deliver the consistent quality that industries demand.
Our caustic soda 25kg bags contain precisely engineered flakes and pearls with exceptional purity levels. We understand that different applications require different grades, which is why we offer multiple purity options:
| Grade | Purity | Available Forms |
|---|---|---|
| Industrial Grade | 99% minimum | Pearls, Flakes |
| Standard Grade | 98% | Pearls, Flakes |
Detailed specifications (99% grade):
Sodium hydroxide (NaOH): ≥ 99%
Sodium carbonate (Na₂CO₃): ≤ 0.5%
Sodium chloride (NaCl): ≤ 0.03%
Iron (Fe₂O₃): ≤ 50 ppm
Appearance: White, uniform flakes or pearls
The crystalline structure of our products ensures optimal dissolution rates, while the uniform particle size guarantees consistent reaction times in industrial processes. Each batch of our caustic soda 25kg products undergoes rigorous laboratory testing to verify chemical stability and physical properties, meeting international standards for industrial-grade sodium hydroxide.
We offer multiple packaging options designed to protect your product during international shipping:
| Package Type | Weight | Container Loading (20ft) |
|---|---|---|
| Multi-layer moisture-proof bags | 25 kg | 27 metric tons |
| Jumbo bags | 1000 kg | 20 metric tons |
| Jumbo bags | 1200 kg | 24 metric tons |

Our caustic soda 25kg bags are essential for saponification, transforming oils and fats into quality soap. The consistent purity ensures complete reactions, producing hard, homogeneous bars with excellent lathering properties. Manufacturers from Vietnam's textile industry to Germany's chemical processing plants consistently choose our caustic soda 25kg for their production needs.
In paper production, caustic soda acts as a powerful delignification agent, efficiently separating cellulose fibers to produce whiter, stronger paper with better printability.
Municipal and industrial water treatment facilities worldwide use our products for pH adjustment, water softening, and heavy metal precipitation.
Ideal for mercerizing cotton, scouring fibers, and preparing fabrics for uniform dyeing and finishing.
Serves as a neutralizer, catalyst, and strong base for organic synthesis, biodiesel production, and acid gas treatment in refineries.
Used in equipment cleaning and disinfection, as well as in the production of pesticides and herbicides.
We understand that incomplete paperwork can delay shipments and create compliance issues. Every order includes:
Certificate of Analysis (COA) confirming purity specifications (98% or 99%)
Certificate of Origin (FORM A, FORM E, etc., based on destination)
Bill of Lading
Packing List
Commercial Invoice
Safety Data Sheet (SDS)
SGS/BV inspection available upon request
