Quality Control

Our N-Phenylbenzothiazole-2-Sulfenamide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with industry specifications for rubber accelerators. Certificates of Analysis (COA) detailing assay, melting point, and ash content are provided with every shipment to guarantee supply reliability and product consistency for your critical formulations.

Storage

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