Description

Calcium Sodium Aluminosilicate is a synthetic, amorphous aluminosilicate compound widely utilized as a functional additive and processing aid. Its primary commercial value lies in its high surface area, porosity, and ion-exchange capacity, making it an effective desiccant, adsorbent, and anti-caking agent. This material is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking to control moisture, improve flow properties, or modify material characteristics.

Application

• Plastics & Polymer Processing: Acts as a moisture scavenger in moisture-sensitive polymer systems like polyurethanes and polyamides to prevent hydrolysis during processing.
• Coatings & Paints: Used as a matting agent and flatting agent to reduce gloss and improve surface texture in industrial and decorative coatings.
• Anti-Caking Agent: Prevents clumping and maintains free-flowing properties in powdered chemicals, fertilizers, and food-grade products (where compliant grades are used).
• Adsorbent & Desiccant: Employed in packaging and gas drying applications to control humidity and adsorb volatile organic compounds (VOCs).
• Ceramics & Refractories: Serves as a fluxing agent and filler to modify thermal properties and improve the workability of ceramic bodies.
• Catalyst Support: Provides a high-surface-area, inert carrier for various industrial catalysts in chemical synthesis.

Quality Control

Our Calcium Sodium Aluminosilicate is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including moisture content, particle size distribution, and chemical composition to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) are provided with every shipment, and we can supply material compliant with relevant food-grade (FCC) or industrial specifications upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
