The Advantages of Using Plastic for Mix Tanks Over Traditional Materials

Mix tanks are specifically engineered for combining and blending a range of chemicals, products and substances. They have many applications in various industries like pharmaceuticals, food/beverage production and chemistry research as well as agricultural markets. Plastic mix tanks — also referred to as poly mix tanks or plastic mixing containers — are garnering increasing popularity due to the numerous benefits they present compared to metal tanks.

This article is your guide to the many advantages and uses of plastic mixing tanks, as well as a variety of selections featured at Tank Depot.

Advantages of Plastic Mix Tanks

There are several reasons why industries are increasingly adopting plastic mix tanks, including:

Corrosion Resistance

One of the key advantages of plastic mix tanks is their resistance to corrosion. Unlike metal tanks that may rust, corrode or degrade over time, plastic mix tanks maintain their structural integrity even when exposed to harsh chemicals and environments. This makes them an ideal choice for industries dealing with corrosive substances.

Lightweight and Easy to Handle

Plastic mix tanks are generally lighter than their metal counterparts, which simplifies transportation, installation and handling. The reduced weight also contributes to lower costs associated with shipping and storage.


Plastic mix tanks can be easily customized to meet specific industry requirements, such as adding heating or cooling systems, agitators and various fittings. This flexibility enables businesses to easily find the right mix tank solution for their particular needs.

Durability and Longevity

Crafted from resilient materials such as polyethylene and polypropylene, high-quality plastic mix tanks are designed to stand up against the test of time. Not only do they provide impressive resistance to impact, abrasion and chemical attack, but the benefits also result in reduced maintenance needs and extended longevity.


Plastic mix tanks tend to be more affordable than stainless steel or other metal tanks. The lower initial investment, coupled with reduced maintenance and replacement costs, makes plastic mix tanks a budget-friendly choice for many businesses.

Disadvantages of Plastic Mix Tanks

Despite the numerous benefits of plastic mix tanks, it’s important to acknowledge a few potential drawbacks:

  • Constructed from polyethylene and PVC, tanks of this type are created to survive between -40°F and 160°F. This temperature range is suitable for most conditions, yet if you experience temperatures beyond these limits, then another kind of tank may be required.
  • Plastic mix tanks can be susceptible to damage from UV rays, which can cause them to crack or become brittle over time. It is essential to ensure that the plastic material used in the mix tank has UV stabilizers or inhibitors (like that provided by Tank Depot) in order to minimize this risk.

Make sure to select a plastic mix tank made from a material that is compatible with the substances it will be storing and mixing. Consult material compatibility charts or guidelines to determine the appropriate tank material.

Tank Capacity

Choose a tank with the appropriate capacity for your application. Consider the maximum volume of substances to be mixed and any additional space needed for mixing, agitation or expansion.

Temperature Range

Ensure the chosen plastic mix tank can withstand the operating temperatures of the substances being mixed and stored.
