In the HPPO - or Hydrogen Peroxide to Propylene Oxide - process, our high-quality hydrogen peroxide is used as an oxidizing agent to oxidize propylene to propylene oxide. Propylene oxide is mainly used in the production of polyurethane foams, which can be found in applications such as mattresses, car seats, or thermal insulation.

Why we believe Solvay is the right partner

We are the leading global producer and supplier of hydrogen peroxide solutions and a technology leader in the hydrogen peroxide production process.
