Tank Material

Our Tanks are available in high-density Polyethylene (also known as HDPE or PEHD) which is an extremely durable thermoplastic resin that is also repairable and in Cross-linked Polyethylene (XLPE) which is a thermoset resin that has superior heat and chemical resistance, stress cracking resistance as well as low-temperature impact strength. Tanks can be made for a Specific Gravity of 1.5 or 1.9 for liquids that are denser than water.
