PU Foam Wheel

PU filled Rubber Tires Under the Microscope

Under the Scanning Electron Microscope (SEM), we can clearly observe the unique open-cell structure of the PU polyurethane tires from Aleader Tire.

We can also identify the uniformity and stability of the cell distribution, with the majority of cell diameters falling within the range of 50 to 100 micrometers.

These characteristics make Aleader's PU tires superior in performance.

Aleader 's PU tires are known for their excellent resilience and stability, as well as their wear resistance, puncture resistance, quiet comfort, environmental-

safety, and high load-bearing capacity. They are widely used in rehabilitation aids, mobility devices, and special equipment.

Unique Foam Filled Internal Structure

This PU foam wheel adopts exclusive integrated foam filling technology, featuring a fully compact inner structure without hollow air cavities. The high-elastic polyurethane foam material perfectly fills the entire tire interior and fits closely with the outer rubber tire shell. Different from ordinary solid wheels with hard and stiff texture, its internal porous structure brings proper flexibility. The whole wheel body maintains stable structural integrity after long-term rolling and extrusion, never producing core displacement or local collapse, with excellent overall structural consistency.

Gentle Shock Buffer & Quiet Running Performance

The finely distributed micro-pore structure inside the tire can effectively disperse ground pressure and filter tiny road vibrations generated during travel. It relieves rigid jolts on rough roads, floor gaps and slight undulations, bringing exceptionally smooth moving experience. Meanwhile, the foam material can absorb friction and collision sounds during rolling, avoiding harsh operating noise. It ensures quiet and stable use in indoor environments, residential roads and daily travel scenarios.
