Effect of Oxidizing Environments on Long-Term Performance of Rotationally Molded XLPE Storage Tanks

Source

Caution should be used when evaluating the long-term storage capability of polymeric materials in direct contact with chemically active solutions. Degradation and cracking of rotomolded, cross linked polyethylene (XLPE) storage tanks that have been used for long-term storage of potentially strong oxidizing liquids have been analyzed. Fractographic, mechanical and chemical evidence indicates that under certain conditions XLPE can be severely oxidized and degraded when concentrated industrial bleach or oxidizing acids decompose or react with the XLPE.
