Caustic Soda Pearls | Granular Sodium Hydroxide (NaOH)

1. Product Overview

2. Product Description & Key Selling Points

Our caustic soda pearls are manufactured through advanced granulation processes, delivering uniform white spherical granules with excellent physical and chemical stability. Compared with flake caustic soda, granular NaOH features low dust, free-flowing properties and easy automatic feeding, which significantly improves operational safety and production efficiency. The 99% high purity guarantees consistent quality across batches, effectively reducing the risk of impurities affecting final products in high-end applications.

As a high-value industrial alkali, caustic soda pearls have obvious differentiated advantages in the global market. They are irreplaceable for automated production lines and highly favored by fine chemical manufacturers, daily chemical brands and pharmaceutical producers. Supported by strong domestic production capacity, we ensure stable supply, sufficient stock and reliable delivery schedules, accepting both small trial orders and large bulk shipments.

We provide one-stop export services with full certifications, professional packaging solutions and flexible trade terms. Our rich experience in serving Middle Eastern, Southeast Asian, South African and European markets enables us to meet regional compliance requirements and local customs standards efficiently.

4. Applications

Our 99% caustic soda pearls cover a wide range of industrial and specialized applications, perfectly matching the demands of modern production and precision processes.

Industrial Fields

Fine Chemical & Pharmaceutical Industry

Widely used for the synthesis of pharmaceutical intermediates such as antibiotics and antipyretic analgesics. Also applied in electronic-grade chemical raw material purification and precise neutralization reactions in spice and dye manufacturing. The high purity ensures stable reaction results and avoids product discoloration or quality deviation.

Water Treatment Industry

Ideal for pH adjustment in automated sewage treatment systems. The dust-free granular form enables clean and safe feeding, while the strong alkalinity effectively neutralizes acidic wastewater. It is also used for scale removal and sterilization in circulating water systems.

Metallurgy & Mineral Processing

A key raw material in mining and metallurgy, especially in South Africa. Used for flotation agent preparation, gold cyanidation leaching and mineral processing wastewater treatment. The uniform particle size ensures consistent dissolving speed and reaction efficiency.

Petroleum Industry

Applied in petroleum refining for diesel and gasoline deacidification. Also used for adjusting viscosity and stability of drilling mud in oilfield operations, supporting smooth exploration and production processes.

Daily Chemical Manufacturing

Serves as a high-purity raw material for premium detergents, cosmetics, hand sanitizers and soap production. Low impurity content prevents finished product discoloration and ensures mild and stable performance in daily care products.

Specialized Fields

Food Processing Industry

Food-grade caustic soda pearls are used for food additive synthesis, such as sodium bicarbonate production, and for regeneration of ion exchange resins in drinking water purification. All food-grade products comply with food safety standards.

Electroplating Industry

Used for the preparation of chromium plating and zinc plating solutions. Also applied in workpiece pretreatment for degreasing and oxide layer removal, ensuring clean and uniform plating quality.

9. FAQ

Q1: What is the difference between caustic soda pearls and caustic soda flakes?
A1: Caustic soda pearls are granular, low in dust, free-flowing and suitable for automated lines. Flakes produce more dust during feeding and are less consistent in dosing. Pearls are preferred for high-end and automated production.

Q2: Do you provide free samples?
A2: Yes, samples are available free of charge; customers only bear the freight cost.

Q3: Can you supply food-grade caustic soda pearls?
A3: Yes, we offer both industrial grade and food grade with complete certifications.

Q4: What certifications are needed for South Africa clearance?
A4: We can prepare SABS certification and a full set of customs documents.

Q5: How to avoid caking during shipping?
