Polypropylene tanks are general-purpose containers that can be customized to fit a variety of specific application needs. Commonly used for liquid chemical storage applications, polypropylene tanks are strong, durable, and lightweight. Polypropylene tanks have excellent thermal insulating properties, which makes them compatible with both high- and low-temperature applications.

What are Polypropylene Tanks Typically Used For?

The unique properties and customizability of polypropylene tanks make them suitable for safely storing a variety of liquids, including chemicals and pharmaceuticals. Common materials stored by these tanks include:

  • Potable drinking water
  • Acids and alkalis
  • Hydrogen sulfide
  • Photographic solutions
  • Potassium carbonate
  • Magnesium hydroxide

What are The Benefits of Using Polypropylene?

Polypropylene plastic has properties that give it advantages over other storage tank materials. Some of these properties include:

  • High temperature tolerance. Polypropylene has a higher melting point than other plastics used for tanks, with certain formulations capable of tolerating temperatures over 300° F.
  • Durability in harsh conditions. These tanks resist damage from abrasion and can withstand UV exposure and excessive pH levels. Polypropylene tanks are also highly resistant to chemicals, including most alkalis and acids, and are more resistant to corrosion than many metal and alloy tanks. Polypropylene can also withstand ​anodizing, electroplating, and cleaning lines, and is ideal for a variety of electroplating applications.
  • Low maintenance. Stainless steel has often been chosen over plastic for storage tanks due to a misconception that resins in poly-based storage tanks would facilitate leaching, leaching, or the growth of microorganisms. In truth, polypropylene mitigates these risks more than stainless steel.
  • Long service life. There is no need for protective coatings since the plastic itself has inherent resistances. Using polypropylene also mitigates the risk of weak welds that lose their integrity or succumb to corrosion over time on metal tanks.

How are ​Polypropylene Tanks Made?

Polypropylene is easily fabricated into tanks up to 1.5 inches in thickness. These versatile tanks may be customized in nearly any shape or configuration, both horizontal and vertical. Custom design capabilities allow for the addition of a variety of control devices such as:

  • Agitation components
  • Anodes
  • Controls
  • Cathodes
  • Covers
  • Flow control
  • Monitors
  • pH monitors
  • Piping
  • Pumps
  • Saddles
  • Temperature controls
