Filler Alfrimal

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

 

Description 
Alfrimal (aluminum tri-nitrate) was added to a poly urethane casting system increases the rigidity of the PU (PU at gietsysteeem D80, for example, of 70 Shore A to a maximum of 85). Alfrimal with the maximum casting thickness PU casting system D80 is 100 mm instead of 30 mm.

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

The addition of Alfrimal prolongs the processing time of 5 to 10 minutes and adding the ontmaltijd from 50 minutes to 180 minutes.The of a small amount of filler will make the PU stronger. Too much filler, however, makes the PU brittle (but louder).
