Filler PU

With PU you can increase the maximum casting thickness of the PU casting system D80 to 80 mm instead of 30 mm.


PU was added to a poly urethane casting system increases the rigidity of the PU (In PU casting system D80, for example, the shore will increase from 70 Shore A to a maximum of 85). The maximum casting thickness of the PU casting system D80 is 100 mm instead of 30 mm when you add this filler.

This filler is self-extinguishing and gives this property partly with the PU in which the filler is mixed.

The addition of PU prolongs the processing time of 5 to 10 minutes and increases the demould time from 50 minutes to 180 minutes. A small amount of filler will make the PU stronger. Too much filler, however, makes the PU brittle (but increases stiffness).

The maximum ratio in a normal polyurethane casting system is Polyol: Isocyanate: PU is 1: 1: 3

In bags of 1.5 kg or 25 kg.
