Quality Control

Our production of Metablen H 632 adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including particle size distribution, glass transition temperature (Tg) analysis, and performance testing in standard PVC formulations. Certificates of Analysis (COA) documenting key parameters are provided with every shipment to support your quality assurance protocols.

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). Keep away from heat sources and open flame. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect performance.
