Quality Control

Our (Dibutylstannylene)Bis(Thioethylene) Diisooctyl Diphthalate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise industry specifications for polymer stabilization. A Certificate of Analysis (COA) detailing purity, tin content, and other critical parameters is provided with every shipment to guarantee supply reliability and consistent performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) after opening to maintain efficacy. Keep away from strong acids, strong bases, and oxidizing agents.
