Quality Control

Every batch of Rexyn (Cl-So4) is manufactured under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Certificates of Analysis (COA) detailing key parameters such as total exchange capacity, moisture content, and particle size distribution are available upon request.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
