Polyurethane modelling board in a medium density of 240kg/m³. This rigid material is perfect for making patterns, models, and even temporary moulds for short production runs. At this medium density it is easily shaped by hand using conventional tools and can be rapidly machined using manual or CNC machine tools. However, this 'medium density' block does not yield the same strength and surface finish as our higher density model board.

Typical Uses

  • Creating master models/patterns/bucks for forming composite moulds.
  • Forming a mould tool for prototyping short runs of composite parts.
  • Building Landscapes/Features in architectural and scenario models.

Advantages

  • Easy workability
  • High dimensional stability
  • High Temperature and chemical resistance
  • Good compressive strength
  • Paints/Seals easily

How to Buy

This board is available in 2 thicknesses; 50mm (2") and 100mm (4") and a range of sizes up to 500mm x 1500mm (19" x 59"), please select the thickness and block size you require from the drop-down menu at the top of the page.

Further Information

How to Use

Shape the material using similar methods to working with MDF or wood, can be easily carved/sawn/drilled/routed/sanded, alternatively, machined using standard manual or CNC equipment, once the desired form has been created, the pattern can then be prepared, if required, for mould release.

There are 2 main options available for achieving a good release from this PU modelling board depending upon the level of finish required. First the pattern needs to be sanded to at least 600grit, it is best to do this dry, as wet sanding will lead to water absorption. The board can be finished to a high gloss with Pattern-Coat, which can be applied by standard spray equipment, or if this is unavailable it can be brushed, sanded flat and polished. Pattern-Coat will accept all forms of mould release agent.

Can’t find the answer you’re looking for?Ask our technical team a question.

The Model board has a Heat Distortion Temperature of 55-60°C and so many vacuum forming processes would generate higher temperatures than the board can comfortable handle. If it's just for a small number of forming then you would probably find that the heat would not transfer excessively into the board and so it would be possible to vacuum form over it but for a production tool it would not be suitable.

If you mean could epoxy resin be used to coat the model board (i.e. to surface it) then yes, this combination would be fine. The only combination to avoid with PU boards and epoxy resin is when you want to release cured epoxy resin off PU board after an elevated temperature cure; in this particular combination there is an issue of cure inhibition caused by hot PU inhibiting the cure of epoxy resin but really this only really means problems for epoxy prepregs off PU boards.
