Sodium hydroxide flakes 99%

Description

1. Product Overview

Sodium hydroxide flakes 99% (caustic soda) is a high-alkalinity industrial base essential for pH adjustment, chemical intermediate production, and cleaning formulations. Its primary industrial use spans alumina refining, pulp & paper processing, soap & detergent manufacturing, and textile treatment. The key value proposition is a consistent 99% purity that minimizes byproduct reactions, reducing process variability and waste. Strategically important as a backbone commodity chemical, its supply stability directly impacts downstream manufacturing costs and operational continuity across global supply chains.

2. Key Specifications & Technical Characteristics

• Chemical composition – NaOH (sodium hydroxide), trace Na₂CO₃ ≤0.5%, Fe₂O₃ ≤0.003%

• Purity grade – 99% minimum, industrial technical grade

• Physical characteristics – White, odorless flakes; bulk density ~0.9 g/cm³; particle size 0.5–2.5 mm; fully soluble in water with strong exothermic reaction

• Packaging options – 25 kg net multi-wall paper/PE laminated bags; 1 MT supersacks; bulk pneumatic tankers

• Shelf life – 24 months in original unopened packaging, stored in dry, <35°C conditions away from humidity and acids

3. Core Industrial Applications

• Pulp & paper – Delignification and bleaching pH control; reduces pulping time by 15–20% compared to lower-purity grades, lowering energy costs

• Soap & detergents – Saponification of fats/oils; 99% purity yields consistent final product viscosity and fewer neutralization rejects

• Water treatment – Municipal and industrial effluent neutralization; faster reaction kinetics reduce tank residence time and chemical dosing variance

• Alumina refining (Bayer process) – Digestion of bauxite; high purity minimizes scaling in heat exchangers, extending maintenance intervals by ~25%

4. Competitive Advantages

• Quality consistency – Batch-to-batch impurity variance <0.1%, verified via ISO 9001:2025-compliant third-party testing

• Supply reliability – Dedicated manufacturing lines with 50,000 MT/month capacity; safety stock held across three continental warehouses

• Logistics capability – 48-hour dispatch for LTL and FCL; export-ready documentation with hazardous cargo certification (IMDG, ADR)

• Cost competitiveness – Direct-from-plant pricing removes broker margins; volume-based tiered discounts for contracts >500 MT/month

• Sustainability – Zero-liquid-discharge manufacturing process; recyclable packaging options available upon request

• Technical support – Full SDS, COA, and application engineering support provided digitally within 24 hours of request

5. Commercial & Supply Information

• Minimum order quantity (MOQ) – 20 MT (bulk)

• Loading capacity – 25 MT per 20’ dry container (palletized supersacks); 27 MT per 20’ bulk flexitainer
