Description

Calciumpolysulphides CAS NO 8028-82-8 is an inorganic chemical compound primarily composed of calcium and sulfur, known for its role as a reducing agent and sulfur source. This product is valued in industrial processes for its ability to facilitate specific chemical transformations and deliver sulfur in a reactive form. It is a critical material for sectors including agriculture, chemical synthesis, and metallurgy, where controlled sulfur chemistry is required.

Application

• Agricultural Fungicide and Acaricide: Used in the formulation of lime-sulfur solutions for controlling fungal diseases and mites on fruit trees, ornamentals, and other crops.
• Chemical Synthesis Intermediate: Acts as a key sulfurating or reducing agent in the production of specialty chemicals, dyes, and pharmaceutical intermediates.
• Metallurgical Processing: Employed in ore flotation and metal extraction processes where its sulfide properties aid in mineral separation.
• Leather Tanning Industry: Utilized in the dehairing and processing of hides.
• Wastewater Treatment: Functions as a precipitating agent for the removal of heavy metals from industrial effluents.
• Rubber Vulcanization: Serves as a secondary vulcanizing agent or accelerator in certain rubber compounding applications.

Quality Control

Our Calciumpolysulphides is manufactured under strict process controls to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests, including assay of active sulfide content and impurity profiling. A Certificate of Analysis (COA) documenting key parameters is provided with each shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Due to its alkaline nature and sensitivity to oxidation and moisture, it is recommended to keep containers sealed under an inert atmosphere for long-term stability. Optimal storage temperature is 15-25°C.
