11-inch Polyurethane Solid Tires
1. Features and Applications
The Poly Foam Filled Tire (commonly referred to as FF Tire) consists of a rubber outer casing and a microcellular polyurethane elastomer core that is filled or inserted into the tire. This construction offers several practical benefits: it is puncture‑proof, never goes flat, requires no periodic maintenance, provides good shock absorption, and delivers reliable safety performance. Consequently, these tires are widely adopted in wheelchairs, mobility scooters, strollers, robots, tool carts, and sports equipment. They satisfy the visual and tactile expectations of conventional rubber tires while effectively eliminating the common drawbacks of pneumatic tires-such as puncture risk, air leakage, sudden deflation, and the need for frequent pressure checks and repairs.
2. Production Technology: Spin‑Cast Molding for Power Wheelchair Tires
The spin‑cast molding process is used to inject the foam filling into the tire. This technique creates a dense, firm tread area while keeping the sidewalls flexible. The foam is distributed evenly and precisely, which ensures consistent shock absorption and contributes to a smooth, comfortable ride for the end user.
