Very stable and rigid foam to fabricate positive moulds and models subject to high mechanical load, for example lasts for shoes and insoles as well as tip additions.
- expansion factor: approx. 1.4
- density: approx. 700kg/m³
- good nailable

Light rigid foam
- expansion factor: approx. 5.0
- density: approx. 300kg/m³
- limited mechanical strength
