Marsh Brothers Aviation AeroTough®-White is a proprietary self-lubricating thermoplastic developed for use as a high-pressure bearing material for food equipment and drinking water applications where extended wear life and lubrication-free operation is desirable. With similar properties to AeroTough® GF it can also be used in cabin equipment applications where a white colour is preferred.


  • Maximum dynamic working pressures up to 55 MPa (7977 psi)
  • Low coefficient of friction (typically 0.10-0.17)
  • Very low wear in non-abrasive environments

Reasonable abrasion resistance – less than other MBA elastomer grades, but better than bronze, epoxy phenolics and many other non-metallic bearing materials.
