Description

Bis(Diphenylcarbamodithioato-S,S')-, (T-4)-Lead CAS NO 75790-73-7 is an organolead compound belonging to the dithiocarbamate class, functioning as a highly effective stabilizer and antioxidant. This compound is critical for enhancing the thermal stability and longevity of polymer materials by inhibiting degradation processes. It is primarily needed by manufacturers in the plastics, rubber, and specialty lubricant industries seeking to improve product performance under demanding conditions.

Application

• Polymer Stabilizer: Acts as a primary heat stabilizer in polyvinyl chloride (PVC) and other halogenated polymers to prevent dehydrochlorination during processing and use.
• Rubber Vulcanization Accelerator: Serves as an ultra-accelerator in the sulfur vulcanization of synthetic rubbers, improving cure rates and physical properties.
• Antioxidant for Lubricants & Greases: Provides antioxidant and anti-wear properties in high-performance industrial lubricants and greases.
• Metalworking Fluid Additive: Used as an extreme pressure (EP) additive and corrosion inhibitor in cutting oils and metal forming fluids.
• Wood Preservative Component: Employed in formulations for protecting wood against fungal decay and insect infestation.
• Agricultural Chemical Intermediate: Functions as a key intermediate in the synthesis of certain fungicides and pesticides.

Quality Control

Our production of Bis(Diphenylcarbamodithioato-S,S')-, (T-4)-Lead adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and heavy metal content are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers must be kept sealed under an inert gas blanket (e.g., nitrogen or argon) after opening to maintain product integrity. Keep away from strong oxidizing agents.
