Polycoat Poly-fil (R) is a two component system where all the air is removed from the tyre cavity and is replaced with a liquid polyurethane rubber. The liquid in the tyre cures at room temperature to a soft, resilient rubber that allows the tyre to maintain the flexing characteristics of a conventional air filled tyre.

Tyres with Poly-fil (R) will not deflate due to puncture of sidewall cuts. Poly-fil (R) allows equipment to operate at maximum efficiency as it reduces downtime due to flat tyres. Poly-fil (R) also helps extend tyre life as the tyre will not be subject to changes in air pressure, so the tyre does not run under or over inflated, which can also improve fuel economy.

Down time and tyre repair costs are substantially reduced when using tyres filled with Poly-fil (R), while efficiency and productivity are improved.

Poly-fil (R) has been manufactured in Santa Fe Springs, California since 1985 by the original chemist that developed the product in 1972.
