The Chlorine Institute's Position on High Density Polyethylene Tanks:

Sodium Hypochlorite Manual, Pamphlet 96, May 2000, Edition 2 --
6.2.2.4 c) Materials of Construction, High Density Polyethylene Tanks

The Chlorine Institute has published their position on high density polyethylene tanks in their Sodium Hypochlorite Manual, Pamphlet 96, May 2000, Edition 2, Rev 1 on page 24 under Section 6.2.2.4 Materials of Construction, section (c) High Density Polyethylene Tanks. The Chlorine Institute states, "Linear and cross-linked high density polyethylene tanks or tanks with these materials as liners have been used in sodium hypochlorite service. The success or failure of these types of tanks depends upon a number of factors including resin type and additives, fabrication technique, product temperature, environmental exposure, the characteristics of the solution (particularly trace metal contaminants) and the installation and piping connection methods. It is advisable to deal only with polyethylene tank manufacturers having experience with sodium hypochlorite and who are willing to warranty the vessel for the intended applications."

Poly Processing Company's High Density Crosslinked Polyethylene tanks clearly meet The Chlorine Institute's requirements:

1. Poly Processing has over 30 years of experience storing Sodium Hypochlorite in HDXLPE tanks.

2. Poly Processing offers a full 5 year warranty on our HDXLPE Sodium Hypochlorite tanks with OR-1000™ and IMFO^®.
