Description

Aluminum Trihydrate CAS NO 8064-00-4 is a white, crystalline powder widely recognized as a key flame retardant and smoke suppressant filler. Its primary value lies in its ability to release water vapor upon heating, effectively diluting flammable gases and cooling the material, which makes it indispensable for enhancing fire safety. This compound is essential for manufacturers in the plastics, rubber, coatings, and construction industries seeking non-toxic, halogen-free solutions to meet stringent safety regulations.

Application

• As a primary flame retardant and smoke suppressant in polyolefins, PVC, epoxy resins, and rubber compounds.
• As a functional filler in wire & cable insulation, carpet backing, and transportation composites to improve fire resistance.
• In the formulation of intumescent coatings and construction materials like siding and panels.
• As a raw material for the production of other aluminum compounds, including aluminum sulfate and alumina.
• As an antacid agent in pharmaceutical preparations (subject to appropriate grade specifications).
• In the paper industry as a filler and coating pigment to improve brightness and printability.
• As a catalyst carrier and adsorbent in various chemical processes.

Quality Control

Our Aluminum Trihydrate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. We offer various grades tailored to specific applications, from industrial flame retardancy to pharmaceutical excipient use. Certificates of Analysis (COA) documenting purity, particle size distribution, and loss on ignition are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive); therefore, the storage area should maintain low humidity to prevent caking and preserve flow properties. Keep away from strong acids.
