Description

Dawsonite CAS NO 12011-76-6 is a naturally occurring and synthetically produced sodium aluminum carbonate hydroxide mineral. This compound is valued for its unique properties, including its role as a flame retardant and smoke suppressant filler in polymer composites. It is primarily sought after by manufacturers in the plastics, rubber, and coatings industries seeking to enhance the fire safety and thermal stability of their products while maintaining material integrity.

Application

As a flame retardant and smoke suppressant additive in polyvinyl chloride (PVC), polyolefins, and various thermoplastics.
As a functional filler in wire and cable insulation compounds to improve fire resistance.
In the formulation of intumescent coatings and fireproofing materials for construction applications.
As a component in rubber goods to enhance flame retardancy and thermal properties.
In the production of ceramics and glass as a source of alumina and sodium.
As a potential precursor for catalytic materials and advanced ceramics synthesis.
In environmental remediation processes for its ion-exchange properties.

Quality Control

Our Dawsonite is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as chemical composition, particle size distribution, and loss on ignition. Our quality management system is designed to meet the rigorous demands of industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep container tightly sealed when not in use to prevent caking and degradation from atmospheric moisture.
