Description

Aluminum Magnesium Hydroxide Carbonate is a high-purity, mixed metal hydroxide compound with a layered double hydroxide (LDH) structure. This material serves as a highly effective halogen-free flame retardant and smoke suppressant for polymers, offering significant environmental and safety advantages over traditional additives. It is also a versatile precursor for catalysts and adsorbents. Key industries that utilize this compound include plastics manufacturing, specialty chemicals, and advanced material science.

Application

• Primary Flame Retardant & Smoke Suppressant: A core additive in polyolefins (PP, PE), PVC, rubber, and wire & cable compounds to meet stringent fire safety standards without halogens.
• Polymer Stabilizer: Acts as an acid scavenger and thermal stabilizer, helping to extend the service life of polymers during processing and use.
• Catalyst & Catalyst Support: Used as a solid base catalyst or a precursor for supported catalysts in various organic synthesis reactions.
• Adsorbent Material: Effective for the adsorption of anions, dyes, and other contaminants from aqueous solutions in environmental remediation.
• Pharmaceutical & Cosmetic Ingredient: Functions as an antacid and buffering agent in pharmaceutical formulations and personal care products.
• Ceramic & Composite Precursor: Serves as a starting material for producing advanced ceramics and nanocomposites with tailored properties.

Quality Control

Our Aluminum Magnesium Hydroxide Carbonate is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent chemical composition, particle size distribution, and performance characteristics. We provide comprehensive Certificates of Analysis (COA) detailing purity, metal content, loss on ignition, and specific surface area. Our production can be aligned with relevant industry standards for flame retardants and polymer additives.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F). Ensure the storage area has low humidity and is well-ventilated. Keep the container sealed immediately after use to prevent moisture absorption and caking.
