Core material for composites: SAERfoam®

SAERfoam is our structural core material with 3D glass bridges. SAERfoam replaces conventional core materials such as PVC, PET and balsa in an innovative manner: Ultralight foam (PU/PE/PIR) is combined with 3D glass reinforcements. The result is SAERfoam, an extremely low-weight hybrid core material with mechanical properties that can be individually optimised. This offers a multitude of benefits for your production process
  1. Stiff and strong product
    Minimized deflection while the sandwich panel is loaded –
    SAERfoam exhibits up to four times greater shear modulus in comparison with PVC and PET.
  2. Economical solution
    SAERfoam offers the most economical solution. Lower material cost than PVC ; lower resin consumption than PET.
  3. Simple to process
    SAERfoam is easy and inexpensive to cut. In curved shapes, the resin consumption furthermore can be reduced by around 1 kg/m² thanks to the natural flexibility of the plain sheets which minimizes the need for a drapable version.
  4. Break-through draping solution without print through
    Since there is no knife cut on the face of SAERfoam placed on the mold side, there is no print through related to resin shrinkage.
  5. Numerous possibilities with SAERfoam +
    Tailor-made solutions for specific core requirements are available – even fire protection solutions are possible.
