Product description:
Di-tert-butyl Polysulfide is a sulfur-rich specialty chemical used primarily in refinery processing and lubricant additive formulations. With a sulfur content of ≥55%, it is suitable for applications requiring an effective sulfur source and stable liquid handling properties.
It is commonly used for hydrotreating and hydrocracking catalyst sulfiding, refinery process applications, and sulfurized lubricant additive systems. ZXCHEM supplies the product in drums, IBC tanks, and bulk shipment options for industrial users.
Product Applications:
- Refinery Catalyst Sulfiding
Used as a sulfur source for the activation and sulfiding of hydrotreating and hydrocracking catalysts in refinery operations.
- Refinery Process Applications
Suitable for selected refinery processes, including applications where sulfur-containing additives are required for process control and equipment operation.
- Lubricant Additives
Used in industrial lubricants, automotive gear oils, and greases to support extreme-pressure, anti-wear, and load-carrying performance.
- Rubber & Specialty Chemicals
Can be used in selected rubber vulcanization, polymer modification, and specialty chemical processes requiring sulfur functionality.
