Products Introduction

Poly Foam Filled Tire, simply called FF Tire, consists of two parts: rubber outer tube, microcellular polyurethane elastomer filled or inserted inside. With the superior performance in the aspects of inflation free, anti- puncture, flat free, good cushioning maintenance free and high security etc., it is widely used in the field of Wheelchairs, Mobility Scooters, Strollers, Robots, Tool carts and Sports Equipment. While satisfying customer's esthetic-demand for traditional rubber tires, it also conquers the defects of air-filled tires: the potential risks of easily punctured, gas leakage, flat tire and frequent maintenance.

Poly Foam Filled Tire's Production Technology: SPIN-Cast Molding

The process of spin-cast molding is used to insert foam fill into tires. This process helps create a dense, firm tread area while keeping the sidewall area flexible. The distribution of the foam fill is even and accurate ensuring excellent shock absorption. This helps provide the user with a smooth ride, every time.

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.
