Hydrogen Peroxide Material Compatibility

35% Hydrogen Peroxide undiluted is an oxidizer and corrosive. Most hot tubs use newer material for seals and gaskets which are compatible with hydrogen peroxide. Although the concentration level is very low after adding 35% Hydrogen Peroxide to a hot tub knowing what materials are best is always good.

Natural rubber is not compatible with hydrogen peroxide. The rubber will break down fairly quickly and the reason “eye droppers”  should not be used to dispense 35% Hydrogen Peroxide.

For Hydrogen Peroxide 30% +.  A “C” rating may work for some industrial application however we do not recommend using materials with a “C” or “D” as to avoid possible unwanted chemical residue from material degradation.

Does 35% Hydrogen Peroxide Freeze?

35% Food Grade Hydrogen Peroxide Does Freeze

Hydrogen 2o2 35% H2O2 should not freeze in a common home freezer.  If you purchased from someone else and your 35% Hydrogen Peroxide freezes it’s NOT 35% H2O2.

35% Hydrogen Peroxide will freeze at or below a temperature of  -34 C. or -29..2 F.  An average home freezer temperature range is between 32 F and 0 F.

20% Hydrogen Peroxide will freeze at or below -15 C. or 5 F.  5 F. falls in the range of a typical home freezer so if your Hydrogen Peroxide freezes in your freezer its not 35%. Our 35% Hydrogen Peroxide will not freeze in your freezer.

Below is a chart showing hydrogen peroxide freezing and boiling points. Continue reading “Does 35% Hydrogen Peroxide Freeze?”
