A fuel containment liner is a crucial component in the storage and management of fuels, designed to prevent leaks and spills that could lead to environmental contamination. These liners are used in various applications such as fuel storage tanks, secondary containment systems, and fuel transfer areas. Typically made from materials that are resistant to hydrocarbons and other chemical agents found in fuels, such as reinforced polyethylene (RPE), polyurethane, or PVC, these liners ensure a robust and impermeable barrier against potential leaks.
