STEPAN MWA-550 is a trimethylolpropane tricaprylate caprate polyol ester that can be used for metalworking formulations in 100% synthetic lubricants for improved lubrication properties, cutting fluids and drawing compounds. STEPAN MWA-550 can enhance the performance of straight oil, semi-synthetic and full synthetic metalworking fluids. STEPAN MWA-550 can offer extreme pressure-type performance without reacting at the work-tool interface. The addition of phosphate esters will enhance performance and replace chlorine.

Regulatory & Compliance
- Chemical Inventories
- Clearances
The international inventories (country clearances) of STEPAN MWA-550 can be found in Section 15 of the Safety Data Sheet (SDS). It is the responsibility of the formulator to review the chemical control regulations for each country where the end-product is intended to be sold or used.
Technical Details & Test Data
- Falex 4-Ball and Falex Pin and Vee Testing
Lubricity is measured using the Falex Four-Ball Wear test and is used to determine the wear-preventing properties of lubricants in metalworking applications. Lubricants are compared using the average size of the scar diameters worn on the three lower clamped balls. STEPAN MWA-550 shows improved lubrication by showing reduced average scar when compared to the current industry standard.
