Description

Potassium Diisononyl Phosphate is a specialized organophosphate salt widely used as an effective surfactant and anti-static agent. Its primary value lies in its ability to modify surface properties, providing lubrication, emulsification, and corrosion inhibition in complex formulations. This chemical is essential for manufacturers in the plastics, lubricant, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Primary anti-static agent and internal lubricant for polymer processing, particularly in PVC and polyolefins.
• Key surfactant and emulsifier component in industrial lubricants and metalworking fluids.
• Corrosion inhibitor additive in hydraulic fluids and specialty oil formulations.
• Processing aid and flow promoter in the production of synthetic resins and plastics.
• Dispersing agent and stabilizer in pigment concentrates and masterbatches.
• Functional additive in textile auxiliaries and fiber spin finishes.
• Component in specialty cleaning formulations and industrial degreasers.

Quality Control

Our Potassium Diisononyl Phosphate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industrial specifications. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment to guarantee traceability and quality assurance for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
