Hydrogen Peroxide

Also known as:

  • Peroxide
  • Dihydrogen dioxide
  • Hydrogen dioxide
  • Hydrogen oxide
  • Oxydol
  • At concentrations above 70%, H2O2 is usually designated as high-test peroxide (HTP)
The Science

Why CPVC Works Well With Hydrogen Peroxide

Chemical corrosion results from strong acids and bases used for water disinfection, pH neutralization and attack from clarification polymers. Microbial corrosion occurs as a result of sludge streams and biological growth in water. As a thermoplastic, Corzan CPVC is chemically inert to most mineral acids, bases, salts and aliphatic hydrocarbons, providing a lifetime of resistance to corrosive chemicals and water of all purity levels – even at high temperatures. The material is also non-conductive and immune to galvanic corrosion.

Drawbacks of Other Materials

The Drawbacks of Other Materials Handling Hydrogen Peroxide

Hydrogen peroxide is among the top most common chemicals that Corzan CPVC reliably handles in industrial applications. Any material will react to hydrogen peroxide in different ways according to concentration levels, temperatures, pressures and nature of the material. But engineers choose Corzan CPVC for hydrogen peroxide acid due to its performance capabilities compared to metals and other plastics.

Carbon Steel: Hydrogen peroxide is corrosive to metal after prolonged use, which creates pitting and leaks. At high, industrial-grade concentrations, carbon steel piping may fail rapidly.

Stainless Steel: Although it holds up much better against hydrogen peroxide’s oxidative effects, stainless steel piping is substantially more expensive than equal- or better-performing alternatives. Stainless steels must also be passivated to create an inactive oxide layer on the wetted surfaces prior to the introduction of hydrogen peroxide which can be hazardous and time-consuming.

PVC (Polyvinyl chloride): PVC pipe lacks the additional chlorine atoms of CPVC and is therefore resistant to the oxidative effects of hydrogen peroxide only at low operating temperatures.
