PU240 Medium Density Polyurethane Model Board

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.

Typisch gebruik

• 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.

Voordelen

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

Hoe te gebruiken

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.
