Products in Anhydrides

STEPAN® MWA-560 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that can exhibit hydrolysis resistance and good thermal stability. It can also exhibit a good hardness/flexibility balance, clarity, and low color. It can be used in metalworking formulations for improved lubrication properties. It shows improved lubrication by showing a reduced average scar when compared to the current industry standard.

STEPAN® MWA-570 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that exhibits hydrolysis resistance and good thermal stability. It exhibits a good hardness/flexibility balance, clarity, and low color. It is used in metalworking formulations for improved lubrication properties and is a great option as a chlorinated paraffin replacement, either alone or with the addition of phosphate esters. It also shows improved lubrication by showing a reduced average scar when compared to the current industry standard.
