Standard Aeroflex®PU Wheels

Highly Durable AERO-FLEX® Polyurethane Flat Free Tires

CEW is a leading provider of AERO-FLEX® PU tires featuring exceptional shock absorbing qualities and unsurpassed durability. These micro cellular polyurethane (PU) tires are exclusively designed to provide a cushioned ride, making them ideal for wheelchairs and other applications. The secret is in the structure of the material. Thousands of microscopic, honeycomb-like cells are formed by a matrix of tough urethane elastomer. These tiny cells make CEW’s tires lightweight and flexible, allowing them to compress and conform to road obstacles just like air-inflated tires.

Because these cells rely on structure and not air pressure for load support, they cannot leak or go flat, and never have to be pumped up or repaired. Hence, they are known as flat free polyurethane tires.

Understand AERO-FLEX® Composite Material

At CEW, we use the AERO-FLEX® formulation to produce microcellular custom polyurethane flat free tires. This compound is produced with a mixture of our proprietary microcellular urethane and composite rubber material. The AERO-FLEX® compound enhances the road grip and adhesion by combining the traction of tread rubber with superior wear and lightweight properties of our patented microcellular urethane material.

Why PU Tires?

Nails, shards, or broken piece of glass may pose a threat to tires. Also, most rubber tires are prone to damage if they are out of use for a while. However, micro cellular polyurethane flat free tires are an exception to this. They are robustly constructed to withstand rough flooring conditions containing all sorts of external hazards. Also, their performance is not affected even after a long period of inactivity. There are several other reasons to choose AERO-FLEX® PU flat proof tires. These include:
  • They possess lower rolling resistance.
  • They have excellent load bearing capacity.
  • They possess outstanding overall toughness; hence these tires last 2-3 times than standard rubber tires. Compared to rubber tires, AERO-FLEX® PU tires can withstand rough floor conditions consisting of debris.
  • They possess exceptional wear and abrasion resistance.
  • They exhibit outstanding resistance to cutting and tearing.
