Poly tanks, or plastic tanks, are more durable and require less maintenance than comparable steel and fiberglass tanks. Poly tanks have several advantages over the traditional metal tanks, which can be fabricated from stainless steel, steel, titanium and even Hastelloy. Their seamless construction provides them with greater impact strength and superior resistance to rust, corrosion, chemicals, and fuel additives. These virtually indestructible tanks have a longer lifespan than steel tanks, which can fracture and leak.

Poly tanks can easily be molded to fit tank compartments, unlike metal tanks, and are simple to install. Poly tanks also cost less overall than steel tanks, which makes them advantageous for companies searching for less expensive storage alternatives. Poly tanks are used in a wide variety of industries and applications including: water treatment and chemical processing industries to hold such hazardous fluids as sodium hypochlorite, sulfuric acid, caustic soda, and hydrochloric acid; industrial manufacturing and processing, used in varied applications such as electroplating, recycling, parts washing and more; automotive, for use in the storage of fuels and oils such as motor oils, fuel oils and diesel fuels; and agriculture, for use in irrigation and fertilization systems for food production applications.
Some of the many types of common plastic materials used to fabricate poly tanks include polyethylene, polypropylene and polyvinyl chloride. Polyethylene (PE) is one of the many types of plastics from which poly tanks can be constructed. Polyethylene, a light, chemical-resistant thermoplastic, is the most commonly used plastic resin for storage tanks. The common types of polyethylene resins include linear high density (HDLPE), cross-linked high density (XLPE), and linear low density (LLDPE) resins. Polypropylene (PP) is another common choice, due to its advantageous characteristics of a lightweight structure and excellent resistance to moisture and heat. Additional beneficial properties include high strength, low density and a melting point of 320ยบ F; in fact, it is even stronger than polyethylene, though less chemically inert. Lastly, polyvinyl chloride (PVC) is another excellent material choice for poly tanks. Polyvinyl chloride features the advantageous physical properties of being able to be combined with various additives in order to offer rigidity or flexibility; opaqueness, transparency or color; and insulating or conductivity. However, polyvinyl chloride has a negative impact on the environment and human health since it contains highly toxic elements that may leech into the ground or atmosphere. Thus, this type of plastic is less commonly used than the other two.
