Impact resistant iron core PU wheel replacement 4 5 6 8 Inch
Performance Comparison
Load Capacity
TPR: Loads 100-500kg, suitable for light loads like strollers and shopping carts.
PU: Dynamic loads up to 5-6 times that of TPR, with a higher static load, making it suitable for heavy-load environments like medical equipment and warehousing and logistics.
Wear Resistance and Lifespan
TPR has average wear resistance and is prone to deformation with long-term use; PU has significantly better wear resistance and a longer lifespan.
Environmental Adaptability
TPR is acid and alkali resistant but has poor temperature resistance (-15°C to 80°C); PU has a wider temperature range (-35°C to 80°C) and is oil and tear resistant.
Quietness
PU has excellent sound absorption properties, making it nearly silent during operation; TPR's quietness is second best, but better than other materials.
