The material density of an inner tank in urban outdoor trash cans directly determines its structural integrity and service life. High-density materials like cross-linked polyethylene (XLPE) or 304-grade stainless steel provide superior resistance to impact, corrosion, and environmental stress. Denser polymers prevent cracking under thermal expansion, while high-density metals resist denting from compaction forces. Municipalities using high-density inner tanks report 40% fewer replacements and reduced leakage incidents. Material density also affects weight capacity – low-density plastics deform under heavy waste loads, whereas high-density alternatives maintain shape integrity. Optimal density ranges between 0.95-1.2 g/cm³ for polymer tanks and 7.9-8.0 g/cm³ for stainless steel variants, ensuring balance between durability and practical handling during maintenance operations.
