Quality Control

Every batch of our methyl methacrylate-styrene-N-phenylmaleimide terpolymer is manufactured under a strict quality management system. We ensure consistent performance through rigorous in-process and final product testing, including analysis of molecular weight distribution, thermal properties, and compositional uniformity. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with each shipment to guarantee it meets your specific application requirements.

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 material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent moisture absorption, which may affect performance.
