ARNCO, represented in Australia by Bearcat Tyres , has released a tyre flatproofing treatment that prevents punctures due to spikes, scrap metal, nails and rocks. It is designed for use on mine sites, construction zones and other harsh industrial environments.

The liquid polyurethane flatproofing polymer is pumped into a tyre through its valve system, replacing all of the air and curing to a resilient synthetic rubber core in 24 hours. The system helps avoid tip-overs due to sudden flats and provides better ballast on steep inclines or overload conditions.

Tyres filled with the flatproofing material last two to five times longer than air-filled tyres. The frequency and costs of tyre repairs are reduced and multiple retreading is possible.

Three grades of Arnco Flatproofing are available. SuperFlex provides maximum deflection and a ride closest to that of an air-filled tyre. It provides a comfortable ride and reduced driver fatigue. It also provides a broader footprint for increased traction in soft ground and excellent shock absorbing characteristics, stability and traction.

RePneu has medium deflection properties and provides excellent heat resistance and high tear strength, compression and softness.

HeviDuty offers minimum deflection and rock-steady stability for large, slow moving off-road vehicles or those under heavy load. It is best suited to aerial lifts, cranes, roof bolters, scalers, scoops and shield haulers. It is also suitable steel mills, scrapyards, land fills, coal mines, factories, construction sites and any other environments hazardous to pneumatic tyres.
