Description

Di-tert-Nonyl Polysulfide is a high-performance sulfur-containing organic compound, primarily valued for its role as a versatile sulfur donor and chemical intermediate. Its unique structure provides excellent thermal stability and controlled reactivity, making it a critical component in advanced material synthesis and industrial processes. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Vulcanizing Agent: Used as a sulfur donor in the vulcanization of synthetic rubbers, such as EPDM and NBR, to improve heat resistance and compression set.
• Lubricant & Grease Additive: Functions as an extreme pressure (EP) and anti-wear additive in industrial lubricants and greases, providing enhanced film strength and protection under high loads.
• Polymer Modification: Serves as a cross-linking agent and stabilizer in the production of specialty polymers and elastomers to modify physical properties.
• Chemical Intermediate: Acts as a key intermediate in organic synthesis for producing other sulfur-containing specialty chemicals, including antioxidants and corrosion inhibitors.
• Oilfield Chemicals: Employed in drilling fluid formulations and as a sour gas scavenger in oil and gas production operations.
• Sealant & Adhesive Formulations: Imparts flexibility and chemical resistance to polysulfide-based sealants and adhesives used in construction and aerospace.

Quality Control

Our Di-tert-Nonyl Polysulfide is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay, sulfur content analysis, and viscosity measurement, to meet precise customer specifications. A Certificate of Analysis (COA) documenting all critical quality parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its properties as a strong oxidizing agent, it must be segregated from reducing agents, flammable materials, and strong acids. Recommended storage temperature is 15-25°C. Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
