Modelling materials
• The working properties, stock forms and sizes, common uses and environmental impact of the following:
– extruded polystyrene foam, e.g. Styrofoam™
– balsa wood
– polymorph
– plaster of Paris.
Polymorph
Polymorph
Polymorph is sometimes considered a Smart material but it is actually a modern material that has thermoplastic properties and can become malleable enough to shape in temperatures as low as 75C degrees; essentially it becomes soft enough to form in hot water.
However, once cooled, it becomes rigid and is quite hard like a thermosetting plastic allowing it to be cut, drilled or even turned on a lathe.
