Description

Butene, Homopolymer, Sulfurized is a specialized chemical additive produced by the sulfurization of polybutene. This process yields a product with enhanced performance characteristics, including extreme pressure (EP) properties and anti-wear capabilities. It is a critical component in the formulation of high-performance lubricants and greases for demanding industrial applications. Key industries that rely on this additive include automotive, metalworking, and heavy machinery manufacturing.

Application

• As a primary extreme pressure (EP) additive in industrial gear oils and transmission fluids.
• As an anti-wear agent in metalworking fluids and cutting oils to protect machinery.
• As a performance-enhancing additive in grease formulations for high-load bearings and joints.
• In the compounding of specialized lubricants for the automotive industry, such as in differential and axle oils.
• As a friction modifier in lubricants for the mining and construction equipment sector.
• For the formulation of corrosion-inhibiting lubricants used in marine and offshore applications.
