What common material is often used for vapor recovery tank liners?

High-density polyethylene (HDPE) is commonly utilized for vapor recovery tank liners due to its favorable properties that make it ideal for this application. HDPE is resistant to a wide range of chemicals, ensuring durability and safety in environments where various fuel vapors and substances may be present. Its impermeability provides an effective barrier that minimizes the risk of leaks and contamination, which is essential for maintaining compliance with environmental regulations.

Additionally, HDPE is lightweight yet strong, making it easier to install and maintain compared to heavier materials. The flexibility of HDPE allows it to adapt to different tank shapes, providing a secure fit that helps prevent vapor leaks. The longevity and reliability of HDPE as a material for tank liners contribute significantly to the efficiency of vapor recovery systems, making it the preferred choice in many installations.

This selection reflects an understanding of the material science behind vapor recovery and the operational needs of these systems in preventing environmental pollution.
