What are the thermal shrinkage properties of acrylic fabric in outdoor trash cans?

Acrylic fabric demonstrates notable thermal shrinkage properties when used in outdoor trash can applications. When exposed to sustained high temperatures typically ranging from 150°F to 200°F (65°C to 93°C), acrylic fibers begin to contract, potentially causing covers to become misshapen or ill-fitting. The shrinkage rate typically falls between 3-5% under extreme heat conditions, though this varies by fabric density and treatment. Unlike natural fibers, acrylic maintains color stability during thermal exposure but loses structural integrity at temperatures exceeding 250°F (121°C). For outdoor trash cans in direct sunlight, black acrylic covers show higher shrinkage rates due to increased heat absorption. Proper ventilation between the cover and container can reduce thermal buildup by up to 30%, significantly minimizing shrinkage effects. Most quality outdoor acrylic fabrics incorporate thermal stabilizers to resist shrinkage below 180°F (82°C), making them suitable for most climate conditions. Regular maintenance including cleaning and proper storage during extreme weather can extend functional lifespan despite inherent thermal shrinkage characteristics.
