CAS 68937-96-2
Product Overview
Di-tert-Butyl Polysulfide (TBPS / DBPS) CAS 68937-96-2 is a specialized organic sulfur compound containing multiple sulfur atoms connected with tert-butyl groups. It is a liquid sulfur donor widely used in rubber manufacturing, lubricant formulations, metal processing oils, and specialty chemical applications.
Due to its active sulfur content, excellent thermal stability, and controlled sulfur release characteristics, Di-tert-Butyl Polysulfide plays an important role as a vulcanizing agent, sulfur-containing additive, and extreme pressure (EP) performance enhancer. It can participate in sulfur crosslinking reactions and provide improved mechanical properties, wear resistance, and long-term durability for industrial materials.
As a professional supplier of organic sulfur chemicals, Shandong Xima Supply Chain Management Co., Ltd. provides stable-quality TBPS CAS 68937-96-2 with professional export services, technical documentation, and reliable global supply capability.
Key Features and Advantages of Di-tert-Butyl Polysulfide
1. Excellent Sulfur Donor Performance for Rubber Vulcanization
The most important feature of Di-tert-Butyl Polysulfide (TBPS) is its ability to release active sulfur during vulcanization processes. The polysulfide structure allows sulfur atoms to participate in crosslinking reactions between rubber polymer chains.
Compared with conventional sulfur additives, TBPS provides more controlled sulfur delivery, helping rubber manufacturers achieve:
Improved crosslinking efficiency
Enhanced tensile strength
Better heat resistance
Improved aging resistance
More stable vulcanization performance
For tire manufacturers, rubber component producers, and industrial rubber processors, TBPS is an effective solution for improving final product quality.
2. Superior Thermal Stability and Processing Safety
Di-tert-Butyl Polysulfide CAS 68937-96-2 demonstrates excellent thermal stability, making it suitable for high-temperature industrial processing environments.
Its chemical structure enables controlled sulfur activity during processing, reducing unwanted premature reactions and helping manufacturers maintain consistent production conditions.
This advantage is particularly valuable in rubber compounding and lubricant additive applications, where processing stability directly affects product performance and production efficiency.
3. Effective Extreme Pressure and Anti-Wear Additive
In lubricant formulations, TBPS / DBPS is recognized as an effective sulfur-containing additive that can improve extreme pressure and anti-wear properties.
When used in lubricating oils and industrial fluids, active sulfur components can react with metal surfaces under high pressure and temperature conditions, forming protective films that reduce direct metal-to-metal contact.
Benefits for lubricant manufacturers include:
- Improved equipment protection
- Reduced friction and wear
- Enhanced load-carrying capacity
- Extended machinery service life
Main Applications of Di-tert-Butyl Polysulfide CAS 68937-96-2
