Composites With Po Foam

New, innovative light weight solutions are essential to react to the increasing pressure of the automotive industry to reduce CO2 emissions. Cross-linked PO foams of Trocellen are media resistant due to their closed cells and show good thermomouldability and temperature resistance. Therefore they suit excellently for creating light and stabile composites.

PU-Composites with soft PO foam

Joint development of Trocellen and Bayer Material Science

  • Bayer Baypreg honeycomb sandwich + layer of PO foam
  • Optional PVC decor layer with high scratch resistance
  • One step compression moulding without additional glue
  • Baypreg F sandwich: very stiff at low weight / high temperature resistance and dimensional stability
  • PO foam: soft touch / good sealing function / good acoustic damping

Sandwich with PO foam + paper

Sandwich with high-tensile outer layer and PO foam core

  • Outer layer of craft liner, glass fibre woven or basalt
  • High stiffness at light weight
  • Stiffness and weight can be adjusted by varying density and thickness of PO foam
  • No water absorption due to closed cell foam
  • Thermomouldability / fast compression moulding

Sandwich with PO foam + resin and glass fibre

Sandwich with high-tensile outer layer + bond bridge in PO core

  • Light weight, good use for resin vacuum process
  • High stiffness at light weight
  • Resin glass fibre woven: high tensile strength / excellent carrier function
  • PO foam: no absorption of resin fluid / flexible forming
