Description

Triisodecyl Phosphate is a high-purity organophosphorus compound widely recognized for its excellent performance as an extreme pressure (EP) additive and anti-wear agent. Its primary value lies in its ability to significantly enhance the lubricity and load-carrying capacity of industrial fluids and synthetic lubricants. This makes it a critical component for manufacturers in the lubricant, metalworking, and hydraulic fluid industries seeking to improve equipment protection and operational efficiency under severe conditions.

Application

• As a primary extreme pressure (EP) additive and anti-wear agent in synthetic and semi-synthetic lubricants.
• Key component in advanced hydraulic fluids and gear oils for heavy machinery and automotive applications.
• Performance additive in metalworking fluids (e.g., cutting oils, drawing compounds) to reduce tool wear and improve surface finish.
• Used in compressor oils and turbine oils to enhance stability and protect against wear.
• As a flame retardant plasticizer and stabilizer in certain polymer and resin formulations.
• Functional additive in specialty greases to improve performance under high load and temperature.
