Polargard ® is a unique Ridderex product. This is a lining product with an extremely good wear-resistance. These polyurethane wear plates can easily be attached and are recommended for use in the handling of almost any abrasive material.


Polargard ® is a material with an extremely good wear-resistance. The product offers many extraordinary properties:

  • Extremely wear-resistant
  • Can easily be attached to different surfaces
  • Non-sticking
  • Sound absorbing
  • Can easily be shaped to the surface to which it is attached


Because of the extreme wear-resistance of the material, process interruption and valuable downtime can be prevented. Polargard ® can be applied as a lining product in vibrating hoppers, chutes, ducts and flumes, skirtboards and surge tanks.
