"Yellow Foam" PU80 Low Density Model Board

Size (nominal)

Please note: the sizes are nominal and can vary from the advertised size. Please take into account a variance of 5-10mm when considering which size to buy.

Polyurethane model board in a very low density of just 80kg/m³ and 100mm thickness. This lightweight material is perfect for hand-worked design studies, program testing/proving (for CNC routers) and lightweight model building. Being a modelboard rather than a PU foam (although the two are very similar) means that this material has a much finer and smoother surface finish than a more granular PU foam would have.

At this low density the pu foam model board it is easily and quickly shaped by hand using conventional tools and can be rapidly machined using manual or CNC machine tools. However, this 'Low Density' block will not result in the same strength and surface finish as the higher density PU600 board.


  • Easy workability by hand
  • Much finer surface finish than a PU foam
  • Low weight
  • Cost effective
  • Large sheet sizes available
  • 100mm sheet thickness
