Frequently Asked Questions
Sodium Hydroxide is a fundamental base chemical for Chile’s core industries. Key applications include:
-
Mining & Mineral Processing: Essential for pH control in copper leaching and neutralizing acidic mine drainage.
-
Pulp Manufacturing: A critical reagent in the Kraft process for digesting wood pulp.
-
Water & Effluent Treatment: Used for pH adjustment and heavy metal precipitation in municipal and industrial wastewater plants.
-
Food & Beverage Production: Employed as a sanitizing agent in CIP systems.
-
Chemical Synthesis: Acts as a key reactant in producing other industrial chemicals and in biodiesel production.
Proper storage is crucial for maintaining product integrity. Solid forms (flakes and pearls) have a 24-month shelf life when kept in their original, sealed packaging in a cool, dry environment. The liquid caustic soda solution has a 12-month recommended expiry time when stored in designated carbon steel or HDPE tanks, protecting it from contamination and concentration changes to ensure process consistency.
Absolutely. We supply certified Food Grade Sodium Hydroxide that meets stringent international and Chilean regulatory standards. This high-purity product is essential for critical sanitization protocols in CIP (Cleaning-in-Place) systems within the dairy, winery, and meat processing sectors, ensuring compliance with export and domestic hygiene requirements.
We optimize international shipping for cost-effectiveness. For solid caustic soda, a 20ft container typically holds 22-24 metric tons, while a 40ft container accommodates 26-27 metric tons of bagged flakes or pearls. For high-volume liquid shipments, we use ISO tank containers, each transporting approximately 21,000 liters of the 50% solution. This logistical planning ensures efficient delivery to major industrial zones across Chile.
The choice between forms impacts handling, cost, and application efficiency. Sodium Hydroxide Flakes offer a versatile and cost-effective solution for general use in water treatment and chemical manufacturing. Sodium Hydroxide Pearls provide superior purity and rapid dissolution with minimal dust, ideal for precision applications in the pharmaceutical and edible oil refining sectors. Liquid Caustic Soda (50% solution) is ready-to-use, maximizing handling efficiency for high-volume consumers in mining and pulp manufacturing, as it requires no dissolution equipment.
