Polartech® EA 700 is an unique, patent-pending emulsifier technology, developed specifically for metalworking applications. To meet the demanding requirements imposed by severe machining conditions, Polartech® EA 700 delivers best-in-class low foam performance when compared to commonly used metalworking emulsifiers. With exceptional emulsion stability even in extreme conditions and its ability to minimize separation, Polartech® EA700 helps to extend fluid life far beyond normal expectations, resulting in lower costs and higher productivity. Soap and scum formation is minimized ensuring clean machine performance, reducing downtime and maintenance costs. Polartech® EA700 is compatible with multiple base stocks allowing for emulsifier rationalization. Having undergone extensive testing in the laboratory and in the field, Polartech® EA 700 comes with confidence in performance, along with Afton’s specialized expertise to enable success.

Typical applications include:
  • Watermix metalworking fluids
  • Other products where emulsion stability or low foam are critical
