What are the impact-absorbing materials for cast iron outdoor trash can bases?

Cast iron outdoor trash cans are prized for their durability and classic aesthetic, but their heavy-duty construction can lead to loud noise and potential surface damage when moved or serviced. To mitigate these issues, impact-absorbing materials are integrated into the base design. Common materials include rubber pads or feet, which provide excellent shock absorption and slip resistance. Polyurethane components offer superior durability and weather resistance, making them ideal for long-term outdoor use. Thermoplastic elastomers (TPE) are another option, balancing flexibility with environmental resilience. These materials reduce vibration, minimize noise during waste collection, and protect underlying surfaces like concrete or pavement from scratches and cracks. Proper selection ensures enhanced functionality and extended lifespan of the trash can.
