What is the Difference Between Polyester and Polyethylene Water Tanks?

The primary purpose of water tanks is to store liquid and use it when needed. These tanks are manufactured from different materials, including polyethylene (plastic), polyester, and stainless steel. In this discussion, we will focus on polyethylene and polyester water tanks.

Polyester water tanks are UV stabilized. This means that polyester tanks allow less sunlight to penetrate, which can be an advantage. Additionally, polyester tanks are designed for on-site assembly, making them suitable for spaces with limited access. These tanks can be produced without being constrained by a specific mold. Standard original colors and white options are available for polyester tanks.

Polyethylene tanks, on the other hand, are UV stabilized, meaning they are not affected by sunlight and offer excellent protection for the contents, making them suitable for storing food and various liquids. Polyethylene tanks are often referred to as plastic tanks in common language. They are available in blue and white options.

Recyclable Polyester Material - What Is It?

Polyester tanks are made from materials such as polymers, thermosets, resins, thermoplastic resins, reinforcing materials, additives, and fillers. These tanks are UV stabilized. In industrial terminology, polyester tanks are also known as fiberglass tanks.

Chemically, polyester falls into the category of polymers with ester functional groups in their main chains. While naturally occurring polyesters are found in nature, synthetic polyester fibers, including most synthetic polyester used today, are made from ethylene, a component of petroleum that can also be derived from other sources. Polyester is a synthetic fiber used in almost every field today, with predominant use in textiles but also in water tank construction.

International Food Safety-Compliant Polyethylene - What Is It?

Polyethylene, often referred to as plastic in common language, is one of the oldest polymers in the thermoplastic family. Polyethylene water tanks are produced from this thermoplastic material. Over time, polyethylene has evolved, and it's now available in three different forms: high-density, low-density, and medium density.

Polyethylene is a chemical substance that is safe for use. It's highly resistant to chemicals and is one of the most durable plastics used for storing chemical substances. However, its resistance to specific chemicals depends on the temperature at which the chemicals are stored.
