Caustic Soda Flakes in South America

Caustic Soda in Djibouti

Caustic Soda Supplier in South America – Comprehensive Overview

Caustic soda (sodium hydroxide, NaOH) is one of the most essential industrial chemicals in South America, supporting a wide range of sectors from chemical manufacturing to mining, water treatment, and petroleum refining. In solid form, it typically appears as white, odorless flakes or pearls that dissolve readily in water, producing heat and forming a highly alkaline solution.

As a trusted caustic soda supplier in South America, we ensure that our products meet international quality standards, offering exceptional purity, stability, and consistent performance across all industrial applications.


Chemical and Physical Properties of Caustic Soda

Property Specification
Chemical Formula NaOH
Appearance White, solid flakes or pearls
Solubility Highly soluble in water, ethanol, and methanol
pH Level Strongly alkaline (approx. 14 in aqueous solution)
Reactivity Reacts vigorously with acids and certain metals
Purity 98–99% (industrial grade)
Odor Odorless

 

These characteristics make caustic soda one of the most versatile and valuable raw materials for industrial use throughout South America.


Types and Grades We Supply

We supply high-quality caustic soda in two main forms—Caustic Soda Flakes and Caustic Soda Pearls—to suit a wide range of industrial applications.

1. Caustic Soda Flakes

Caustic soda flakes are solid white crystals with a purity level of 98–99%. They are easy to store, handle, and dissolve, making them ideal for industries such as:

  • Pulp and paper – for pulping, bleaching, and deinking processes.

  • Textile – for mercerizing cotton and improving dye absorption.

  • Water treatment – for neutralizing acids and removing impurities.

  • Petroleum refining – for sulfur removal and pH adjustment.
    Caustic soda flakes are favored for their long shelf life, ease of transport, and high solubility.

2. Caustic Soda Pearls

Caustic soda pearls are small, spherical granules of sodium hydroxide with the same high purity as flakes. Their uniform particle size ensures precise dosing and controlled dissolution. They are widely used in:

  • Soap and detergent production – for saponification and cleaning formulations.

  • Pharmaceutical and cosmetic manufacturing – for controlled chemical reactions.

  • Food industry applications (under regulation) – for peeling fruits and vegetable processing.
    Their low dust formation and consistent quality make them a preferred choice in automated industrial systems.

Grades Available

We supply two primary grades of caustic soda suitable for different industrial standards:

  • Industrial Grade (98–99% purity): Ideal for large-scale applications such as mining, textiles, and refining.

  • Technical Grade (96–98% purity): Suitable for detergent, cleaning, and water treatment industries.

Both grades comply with international quality specifications, ensuring maximum efficiency and reliability in production processes.


Applications and Industrial Uses of Caustic Soda in South America

1. Chemical Manufacturing

  • Used in the production of soaps, detergents, surfactants, and dyes.

  • Essential for neutralization and saponification reactions.

  • Supports the manufacture of pharmaceuticals, resins, and plastics.

2. Pulp and Paper Industry

  • Used in wood pulping, bleaching, and deinking.

  • A vital chemical for recycled paper production in countries like Brazil and Chile.

3. Mining and Metallurgical Sector

  • Integral to bauxite refining for aluminum production.

  • Applied in ore processing and gold extraction to separate valuable minerals.

  • Used in wastewater treatment within mining operations to neutralize acidity.

4. Textile and Leather Processing

  • Enhances fiber strength and dye uptake in cotton.

  • Removes fats and impurities in leather tanning processes.

5. Water and Wastewater Treatment

  • Neutralizes acidic effluents.

  • Removes heavy metals and organic contaminants.

  • Maintains stable pH levels in industrial and municipal water systems.

6. Petroleum and Gas Industry

  • Used to refine crude oil, remove acidic impurities, and desulfurize fuels.

  • Improves process efficiency and environmental compliance in refineries.

7. Food and Beverage Industry

  • Applied in limited food processing under strict supervision.

  • Used for fruit peeling, cocoa treatment, and soft drink formulation.


Handling and Storage Guidelines

Caustic soda is corrosive and hygroscopic, requiring careful handling and storage to ensure safety:

  • Always wear protective gloves, goggles, and clothing.

  • Avoid contact with skin or eyes; rinse with plenty of water in case of exposure.

  • Store in cool, dry, well-ventilated areas, away from acids and moisture.

  • Use HDPE-lined or polyethylene containers for packaging.

  • Keep containers sealed to prevent moisture absorption.

Safe handling ensures both operator protection and product stability during transportation and use.


Caustic Soda Market and Supply in South America

The South American caustic soda market is expanding rapidly, driven by increased demand in mining, pulp & paper, water treatment, and petrochemical industries. Key consumers include Brazil, Argentina, Chile, Peru, and Colombia, where industrial growth has boosted the need for reliable sodium hydroxide suppliers.

We are committed to supporting this growth by delivering high-purity caustic soda flakes and pearls that meet the demands of diverse industrial applications. Our logistics network ensures efficient delivery to major ports and industrial hubs across South America, maintaining consistent supply and competitive pricing.


Packaging and Transportation 

Proper packaging preserves product quality and prevents contamination during shipment:

  • Standard Packaging: 25 kg two-layer laminated PP bags.

  • Bulk Packaging: 1250 kg jumbo bags for industrial use.

  • Container Loading:

    • 20-foot container = approx. 25 metric tons (1,000 bags × 25 kg).

    • All shipments are palletized and shrink-wrapped to protect from humidity.

We ensure all shipments comply with international transport and safety standards for corrosive substances.
