Caustic Soda Pearls CAS 86 183 5411 1608

Caustic Soda Pearls

Caustic Soda Pearls are a versatile and highly important chemical raw material, widely used across numerous industries for their powerful alkaline properties and high purity. Also known as sodium hydroxide (NaOH) pearls, these solid granules are preferred for ease of handling, precise dosing, and efficient storage compared to liquid forms.

Serving clients with integrity, our focus is on delivering superior chemical materials that support manufacturing, processing, and environmental management needs.

Product Overview: Caustic Soda Pearls

Caustic Soda Pearls typically appear as white, spherical granules with high purity levels generally above 99%. Due to their highly alkaline nature, they are extremely reactive and require proper handling and storage to maintain stability and safety.

Common Grades and Specifications

• Industrial Grade: High purity (≥99%), suitable for metallurgical, chemical, and pulp & paper industries.
• Food Grade: Manufactured under stringent food safety conditions, used in food processing (e.g. peeling of fruits and vegetables).
• Pharmaceutical Grade: Purified form for pharmaceutical and cosmetic applications.

Characteristics

• Appearance: White, spherical or pearl-shaped granules.
• Purity: Typically ≥ 99% NaOH content.
• Solubility: Highly soluble in water, exothermic dissolution.
• Alkalinity: Strongly alkaline with pH > 13 in aqueous solution.
• Non-flammable solid but highly corrosive.

Production Process

Caustic soda pearls are produced predominantly via the chloralkali process, where brine (sodium chloride solution) undergoes electrolysis to generate sodium hydroxide, chlorine gas, and hydrogen gas. The pure sodium hydroxide solution is then concentrated until molten, extruded, and cooled to form pearls or granules. These pearls are dried, screened, and packaged under controlled environments to prevent moisture absorption and caking.

Common Applications & Uses

Caustic soda pearls have wide-ranging industrial and commercial applications, including but not limited to:

• Pulp and Paper Industry: Used in pulping wood to separate lignin and in paper processing.
• Chemical Manufacturing: Key raw material for producing detergents, soaps, dyestuffs, and other chemicals.
• Water Treatment: pH adjustment and neutralization of acidic waters.
• Metal Processing: Used for cleaning and etching metals, and metal recovery processes.
• Food Industry: Used in food processing such as peeling of fruits and vegetables, cocoa processing.
• Pharmaceuticals and Cosmetics: Used to adjust pH and as a raw material in manufacturing processes.

Packaging and Export

Caustic soda pearls are commonly packed in moisture-resistant bags such as multi-layer kraft paper bags with polyethylene liners or in polypropylene bags to ensure protection from humidity and contamination. Bulk packaging options include jumbo bags (FIBCs) and drums depending on customer requirements and export standards.

Standard packaging weights typically range from 25 kg bags to 1000 kg bulk bags for industrial consumers. Proper packaging and storage conditions are essential to maintain product integrity during transport and storage, especially for export markets subject to varying climatic conditions.
