Puroxit

Composite sandwich panels PUROXIT® are a revolutionary construction element that will allow your project to significantly reduce the weight when keeping excellent mechanical properties. Thanks to our long-term experience in the sphere of composite materials, we developed sandwich composite panels making a special core material with a very low weight, having fibreglass coating on both sides.

Thanks to materials chosen in the product, PUROXIT® is 35% lighter than plywood with the same thickness, simultaneously keeping identical mechanical properties. In addition to its complete resistance to fire (and salt water, too), its additional bonus consists of sufficient thermally-insulating properties, with the ability of dampening noise. The most important feature of the panels is their fire-resistance while PUROXIT® panels meet the requirements on being used in public transport means in compliance with the German norm DIN 5510-2 or the new European norm EN 45 545. Owing to this fact, the product has become the main application in floor structures of trains, trams or buses.

ADVANTAGES

  • very light material (35% lighter than plywood)
  • hight strength makes the board convenient material for transport vehicle floors
  • great thermal insulation
  • acoustic insulation
  • non-flammable material (fulfilling the DIN 5510-2 and EN 45 545)
  • easy to glue
  • can be joined into large units, whereas the joints would not concentrate tension
  • waterproof (even in salt water)
  • possibility to shape (3D parts)

APPLICATION

  • railway (floor in trains and trams)
  • buses (floor)
  • vans and small lorries (floor)
  • trailers (front side, floors)
  • building and construction
  • ship building
