Description

Formaldehyde, Polymer With Isononylphenol, Methyloxirane And Oxirane, Block is a specialized block copolymer surfactant synthesized from formaldehyde, isononylphenol, methyloxirane (propylene oxide), and oxirane (ethylene oxide). This engineered polymer is valued for its exceptional performance as a nonionic surfactant, offering a unique balance of wetting, emulsifying, and dispersing properties. It is a critical raw material for formulators in the industrial cleaning, agrochemical, and coatings industries who require high-performance, stable additives.

Application

• Industrial & Institutional (I&I) Cleaners: A key component in heavy-duty degreasers, alkaline cleaners, and floor care formulations for its superior wetting and soil emulsification.
• Agrochemical Formulations: Used as an emulsifier, dispersant, and stabilizer in pesticide and herbicide concentrates (EC, SC, SE formulations) to enhance efficacy and tank-mix stability.
• Coatings & Paints: Acts as a pigment dispersant and grinding aid, improving color development, gloss, and stability in water-based and solvent-based coating systems.
• Metalworking Fluids: Provides emulsification and surface wetting in synthetic and semi-synthetic coolants and drawing compounds.
• Textile Processing: Employed as a scouring agent, dye leveling agent, and finishing aid due to its compatibility with various process chemicals.
• Pulp & Paper: Functions as a de-inking agent, dispersant, and processing aid in pulp washing and paper coating operations.
