is a structural moulded polyurethane. It has brought a big innovation in the subject of inserts, going beyond the thickness limits imposed by a traditional metal armature. It is therefore possible to use Polstrong to make very thin structures (inserts), but very resistant at the same time.
It has a high mechanical resistance and shock resistance.
The structures made of Polstrong can be then covered with fabric (fabric can be tacked directly on Polstrong) or moulded over again with Polflex or Freeform, painted with glossy or matt finish (see Painted Polstrong).
Average density 600 kg/m3.
