Description

Sorbitan, Mono-9-Octadecenoate, Poly(Oxy-1,2-Ethanediyl) Derivs., (Z)-, Polyisobutenylbutanedioates is a high-performance, non-ionic surfactant and emulsifier derived from sorbitan oleate and polyisobutylene succinic anhydride (PIBSA). This specialized chemical offers exceptional surface activity and compatibility, making it a critical component for formulating stable, high-performance industrial products. It is essential for manufacturers in the lubricant, fuel additive, and polymer industries seeking to enhance product stability, dispersancy, and performance under demanding conditions.

Application

• Lubricant & Fuel Additives: Acts as a highly effective dispersant and detergent in engine oils, gear oils, and industrial lubricants to prevent sludge formation and deposit buildup.
• Polymer & Resin Modification: Used as an internal or external additive to improve the processing, flow, and anti-static properties of various polymers and plastic compounds.
• Industrial Emulsification: Serves as a key emulsifier and stabilizer in the production of water-in-oil (W/O) emulsions for metalworking fluids, coatings, and agricultural formulations.
• Asphalt & Bitumen Modification: Enhances the adhesion, cohesion, and aging resistance of asphalt binders and bituminous products for road construction and roofing.
• Corrosion Inhibition: Functions as a component in corrosion inhibitor packages for protecting metal surfaces in closed-loop systems and industrial fluids.
• Printing Inks & Coatings: Improves pigment wetting, dispersion stability, and flow characteristics in solvent-based and oil-based ink and coating systems.
