PowerMax PXM40 is an anion rich mixture of PX250 H (a hydrogen form macroporous strong acid cation resin) and PX650 OH (a hydroxide form macroporous type 1 strong base anion resin). The high crosslinking gives PowerMaPXM40 added resistance to oxidation due to radiation, thermal, and chemical stressors. PXM40 is intended for use in polishing mixed beds that require high resistivity, high strength and extended resistance to oxidation.

PowerMaPXM40 is supplied ready to use with the cation component in the hydrogen form and the anion component in the hydroxide form.
