Description

Aluminum Hydroxide Hydrate is a versatile inorganic compound widely utilized as a precursor, intermediate, and functional additive across multiple industries. Its primary value lies in its amphoteric nature and thermal decomposition properties, making it a key material for producing alumina and acting as a flame retardant filler. This product is essential for manufacturers in the ceramics, polymer composites, pharmaceuticals, and water treatment sectors seeking a reliable and consistent raw material.

Application

• As a primary raw material for the production of aluminum oxide (alumina) and aluminum chemicals.
• As a highly effective, non-halogenated flame retardant and smoke suppressant in plastics, rubber, and epoxy resins.
• As an antacid active pharmaceutical ingredient (API) and excipient in pharmaceutical formulations.
• As a clarifying agent and adsorbent in water purification and wastewater treatment processes.
• As a filler and reinforcing agent in ceramics, glass, and advanced composite materials.
• As a catalyst and catalyst support in various chemical synthesis reactions.
• In the manufacture of glass, abrasives, and refractory materials.
• As a mordant in the dyeing of textiles.

Quality Control

Our Aluminum Hydroxide Hydrate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, particle size distribution, and loss on ignition. Certificates of Analysis (COA) documenting these parameters are provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and degradation due to moisture absorption.
