Description

1-Propene, 2-Methyl-, Sulfurized is a specialized organosulfur compound derived from the reaction of isobutylene with sulfur. This product is valued for its role as a high-performance additive, providing essential properties such as extreme pressure (EP) and anti-wear protection. It is primarily sought by formulators in the lubricant and metalworking fluid industries who require advanced sulfur carriers to enhance the performance and longevity of their finished products.

Application

• As a key sulfur-based extreme pressure (EP) additive in industrial gear oils and transmission fluids.
• As an anti-wear agent in metalworking fluids, including cutting oils, grinding fluids, and drawing compounds.
• As a performance additive in greases to improve load-carrying capacity and protect against scuffing.
• As a sulfur donor in the formulation of specialty lubricants for heavy-duty and high-temperature applications.
• As a friction modifier in certain automotive and industrial lubricant packages.
• As a chemical intermediate for the synthesis of other organosulfur compounds.
