Polyurethane (PU) elastomer tire technology: Opening a new era of tire that is free of air and resistant to punctures - Feilong Polyurethane Machinery Equipment Factory


In today's era of rapid development of special vehicles and shared micro-mobility tools, the problems of tire blowouts and air leakage in traditional pneumatic tires have become a major pain point in the industry. The Feilong polyurethane machinery equipment, through the innovative application of polyurethane elastomer materials, has developed a revolutionary airless and puncture-resistant tire solution. This provides safer and more durable options for special transportation, shared e-bikes, AGV logistics vehicles and other fields.

I. Technical Core: Breakthrough Advantages of Polyurethane Elastomers

The Feilong polyurethane equipment uses high molecular weight polyurethane (PU) material and is manufactured through precise casting molding process. The resulting elastomer tires have three core characteristics:

Honeycomb structure design: The internal biomimetic honeycomb support structure can achieve an equivalent tire pressure of 100-300 kPa, and the dynamic load capacity exceeds 500 kg.

Anti-puncture performance: The Shore hardness can be adjusted from 75A to 95D. The puncture resistance is more than three times that of natural rubber (according to ASTM F1922 testing standard).

Energy recovery rate: The dynamic recovery rate is > 85%, and the rolling resistance is 15-20% lower than that of traditional tires.

II. Innovative Applications in Special Vehicles

For special scenarios such as mining vehicles and military vehicles, Feilong has developed the patented PU-ARMATURE™ composite technology:

Multi-layer composite structure: Surface wear-resistant layer (wear rate < 0.03 cm³/km) + Intermediate energy-absorbing layer (impact absorption rate 92%) + Bottom support structure

Wide temperature range adaptability: Maintains elasticity in the temperature range of -40°C to 120°C (in line with GJB 150.3A low-temperature test standards)

Test data from a certain type of military unmanned vehicle shows that it can continuously travel 8,000 kilometers on a road containing iron filings and crushed stones without any structural damage.

III. Upgrade Plan for Shared Micro-Mobility Tools

For the frequent usage scenarios of shared e-bikes, Feilong has launched the ECO-RIDE™ series of solutions:

Maintenance-free design: Lifespan up to 30,000 kilometers (2.5 times that of ordinary pneumatic tires)

Economic assessment: Although the cost of a single tire increases by 40%, the overall maintenance cost is reduced by 60%

Green environment: Uses recyclable polyurethane materials, reducing 2.3 kg of rubber waste per tire

IV. Industrialization Process and Technical Barrier Breakthrough

The fifth-generation PU intelligent pouring equipment independently developed by Feilong has achieved:

The production cycle has been reduced to 8 minutes per tire (while the traditional process takes 25 minutes)

The size range covers 12-42 inches of tire specifications

Key indicators:

Dynamic fatigue test: > 500,000 cycles (in accordance with GB/T 13203 standard)

Braking distance on slippery road surface: 1.2 meters shorter than that of the same-level pneumatic tires (tested at 60 km/h)

Currently, this technology has obtained 23 invention patents and two intelligent demonstration production lines have been built in Zhengzhou and Suzhou, with an annual production capacity of 600,000 pieces.

V. Future Development Direction

Fenglong is collaborating with several universities to develop the next generation of technologies:

Intelligent sensing polyurethane tires (integrating tire pressure/temperature sensors)

Variable stiffness material technology (automatically adjusting elastic modulus according to speed)

4D printing topological optimization structure (further reducing weight by 30%)

Conclusion:

With the successful acquisition of German TUV certification and the obtaining of the EU CE mark, the Flong polyurethane elastomer tire technology is reshaping the industry standards for non-inflated tires. This innovation not only meets the extreme working conditions of special vehicles, but also provides a product solution that better complies with the requirements of the circular economy for shared micro-mobility, demonstrating the breakthrough capabilities of Chinese manufacturing in the application of advanced materials.
