Material Selection Guide


Polyethylene is a strong thermoplastic, with excellent resistance to physical damage and chemicals. It can be used for tanks and containers in industrial, agricultural and food settings, due to its superior chemical resistance. Its natural color ranges from light white to creamy yellow, depending on wall thickness and type. Additionally, ultraviolet light stabilizers can be added for outdoor usage if necessary. Furthermore, there are added options for custom colors upon request for a nominal fee; polyethylene is also BPA-free material.

Linear Polyethylene

Linear Polyethylene is a form of polyethylene that can be found in three densities – low, medium, and high. The most commonly used are Medium and High-Density Polyethylene (LMDPE and LHDPE) due to their superior mechanical properties, high stiffness, excellent low-temperature impact strength and environmental stress crack resistance. It also meets FDA regulations for food contact applications such as 21CFR177.1520 (c) 3.1 and 3.2 for maximum operating temperatures of 140° F. Additionally, it is completely BPA-Free making it safe to use in food products!

Crosslinkable Polyethylene

Crosslinkable polyethylene (XLPE) is a type of high-density polyethylene that has been modified with a crosslinking agent. This agent reacts with the polyethylene during molding, creating a reinforced molecular chain that gives the material improved toughness and resistance to environmental stress cracking. Unfortunately, XLPE is not weldable and does not meet the criteria set out by FDA 21CFR177.1520. The maximum recommended operating temperature of this material is 150°F (65°C).


Polypropylene (PP) is a type of rigid plastic that has a higher maximum operating temperature than polyethylene at 212°F. It offers good chemical resistance, high stress crack resistance and is autoclavable. However, it does have limitations in its ability to withstand sub-zero temperatures or any application requiring high impact strength. Its interior surface has a tendency to be rough and irregular due to the molding process.

Consideration to Material Selection

Elevated temperatures

Elevated temperatures can have adverse effects on the lifespan of a tank or vessel, especially when used for an extended period of time. The degree to which temperature may affect the structure of the tank depends on various factors such as its material of construction, size, configuration, and wall thickness. It is also important to consider the concentrations of chemicals being stored inside and their corresponding specific gravity.

Exposure to ultraviolet (UV)

Exposure to ultraviolet (UV) light can have detrimental effects on unprotected thermoplastics. This exposure leads to discoloration, embrittlement, cracking, and accelerated rates of damage in hotter climates. To combat this problem, Chem-tainer utilizes the latest UV stabilizing technologies for their products. Placing tanks in shaded areas or ordering dark-colored tanks can also reduce exposure to UV rays and extend the life of the plastic material.

Environmental stress cracking (ESC) 

Environmental stress cracking (ESC) is a type of degradation to plastics caused by exposure to a combination of stress and certain surface-active materials. These can include common liquid detergents, ultra-pure water, and other chemicals. Elevated temperatures tend to accelerate stress cracking and all polyethylene are prone to this form of degradation. However, some materials are more resistant than others. That’s why it’s important to design tanks and systems that minimize stress, as well as using materials that are highly resistant to ESC. Chem-tainer tanks, for example, are molded visually stress free, with less risk of cracking than fabricated tanks. To prevent the occurrence of ESC it is important to take care when filling and handling the tank, avoiding putting unnecessary stresses on the plastic components where possible.

Key Takeaways:

  • Chem-tainer tanks are designed for superior quality and long-lasting reliability.
  • Chem-tainer tanks can withstand extreme temperatures, resist UV degradation, and offer superior chemical resistance.
  • Chem-tainer tanks are made with FDA-approved resins that are safe and non-toxic for food and beverage contact.
  • Chem-tainer tanks offer a material selection guide, including polyethylene, linear polyethylene, crosslinkable polyethylene, and polypropylene.
  • Elevated temperatures can affect the lifespan of the tank, and considerations should be made based on material, size, and configuration.
  • Exposure to UV light can be mitigated through UV stabilizing technologies and placing tanks in shaded areas.
  • Environmental stress cracking (ESC) is a type of degradation that can occur in plastics, and tanks should be designed to minimize stress and use materials resistant to ESC.
