Dörr-Elastoflex® is a elastomer bitumen block.

Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
It is used for bonding bituminous roofing sheets and cellular glass insulation.

Elastoflex® is melted in commercial bitumen digesters to reach the necessary processing viscosity. Processing temperatures above +200 ° C should be avoided, the processing temperature is approximately +180 to +200 ° C.

For full-surface bonding of bituminous waterproofing layers: about 2.0 to 2.5 kg / m².
For full-surface bonding of cellular glass insulation: approximately 4.0 to 6.0 kg / m².
