Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.,.Alpha.'-Phosphinicobis[.Omega.-(Pentadecyloxy)-, Branched is a specialized non-ionic surfactant and phosphinate ester, valued for its unique branched alkyl chain structure. This chemical offers exceptional performance as a stabilizer, emulsifier, and rheology modifier in demanding formulations where linear analogs fall short. It is a critical component for industrial manufacturers in sectors such as polymer processing, advanced lubricants, and specialty coatings, who require reliable supply and consistent quality to maintain their production standards.

Application

• Polymer Additive: Acts as a processing aid, internal lubricant, and anti-static agent in the production of engineering plastics and synthetic fibers.
• Lubricant & Grease Formulation: Serves as an extreme pressure (EP) additive and friction modifier in high-performance synthetic lubricants and industrial greases.
• Coating & Ink Industry: Functions as a dispersing agent and flow control additive in solvent-based and high-solid coatings, paints, and printing inks.
• Personal Care & Cosmetics: Used as an emulsifier and stabilizer in high-end cosmetic formulations, including creams, lotions, and hair care products.
• Textile Auxiliaries: Employed as a softening agent, antistatic agent, and dyeing assistant in textile finishing processes.
• Metalworking Fluids: Enhances the stability and lubricity of synthetic and semi-synthetic metalworking fluids and coolants.
