Magnesium Hydroxide Technical

Product Overview

Magnesium Hydroxide Technical (Mg(OH)₂) is a white solid powder widely specified for industrial chemical processing and environmental management. With a typical assay of 97.5%, this high-purity technical grade material offers consistent performance in neutralization, buffering, and acid-scavenging applications. It serves as a safer, more controlled alternative to stronger alkalis like caustic soda, providing a buffering effect that prevents pH overshoot.

In industrial operations, Magnesium Hydroxide acts as a primary neutralizing agent for acidic wastewater and flue gas desulfurization. Its low solubility allows for the gradual release of hydroxide ions, maintaining stable pH levels in biological treatment systems. The material exhibits a density of approximately 2.36 g/mL at 25°C and rigorous impurity controls for chlorides and heavy metals, making it suitable for sensitive formulation strategies in plastics, flame retardants, and composite materials.

Common Applications

• Wastewater Treatment: Used to adjust pH levels in effluent streams, providing controlled neutralization and precipitation of heavy metals without the risk of drastic pH spikes.
• Flue Gas Desulfurization: Captures sulfur dioxide (SO₂) in scrubbing systems to reduce industrial emissions.
• Flame Retardant: Incorporated into construction materials and plastics to enhance fire resistance through endothermic decomposition and char formation.
• Plastic Filler: utilized in polymer formulations to improve mechanical properties, dimensional stability, and processing behavior.
• Chemical Manufacturing: Acts as a raw material and neutralizing agent in chemical synthesis and catalyst production.

Safety Precautions

Handle Magnesium Hydroxide Technical with appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves, safety goggles, and protective clothing to prevent dust irritation. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Keep containers tightly closed to prevent moisture absorption.

First Aid: In case of eye contact, rinse cautiously with water for several minutes. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air. Refer to the Safety Data Sheet (SDS) for comprehensive handling and emergency procedures.
