FMC is the worlds largest and only North American producer of peroxydisulfates, or persulfates. Our ISO 9002 Certified production facility in Tonawanda, NY boasts over 70 years of peroxygen experience.

Our goal at FMC is to provide a reliable supply of high quality, stable persulfates to the global market. Our ammonium, sodium, and potassium persulfates, measured for thermal stability, are among the most stable persulfates available in the world.

Persulfates use oxidation and free radical chemistry during reaction. They can therefore be used in a variety of applications such as polymer initiators, printed circuit board etchants, and hair bleach performance enhancers.

Persulfates are strong oxidants which have excellent shelf life when stored properly and are economical to use. Click on the below table for more information on our persulfates.
