Caustic Soda Flakes 99% — Sodium Hydroxide Industrial Grade

Caustic Soda, chemically known as Sodium Hydroxide (NaOH), is a widely used inorganic alkaline chemical for industrial manufacturing, chemical processing, water treatment, pulp and paper production, textile processing, detergent manufacturing, petroleum processing and other technical applications.

Our industrial-grade Caustic Soda Flakes are supplied with a target Sodium Hydroxide content of ≥99.0%, subject to the applicable product specification and batch Certificate of Analysis.

The product is typically supplied as white hygroscopic flakes that dissolve readily in water and produce a strongly alkaline solution.

Sodium Hydroxide is an important basic raw material for industrial processes requiring alkalinity, pH adjustment, neutralization, cleaning, chemical conversion or process control.

Packaging & Storage

Packaging

Standard export packaging:

25 kg PP woven bags with moisture-resistant PE inner liner

Typical container loading depends on:

• bag configuration
• palletization
• shipping regulations
• container weight restrictions
• destination-country requirements

Commercial loads of approximately 25–26 MT per 20-foot container are commonly seen in the market, but the final loading quantity must be confirmed by the supplier and freight provider.

Storage

Store Caustic Soda:

• In a cool location
• In a dry area
• In a well-ventilated warehouse
• In tightly sealed original packaging
• Away from moisture
• Away from acids
• Away from incompatible metals and materials
• Away from unauthorized personnel

Caustic Soda readily absorbs moisture and carbon dioxide from the atmosphere.

Packaging should remain securely closed when not in use.

Handling

Sodium Hydroxide is highly corrosive.

Personnel should follow the current Safety Data Sheet and use appropriate personal protective equipment.

Appropriate PPE may include:

• Chemical-resistant gloves
• Chemical protective clothing
• Safety goggles
• Face shield where splash exposure is possible
• Suitable footwear
• Appropriate respiratory protection where required by risk assessment

Avoid contact with eyes, skin and clothing.
