UNIZELL PU-Foam HR-AT is a 2-component rigid foam based on polyurethane with at least 91 % closed pores. The foam has a cup density of approx. 50 kg/m³. Due to its long reaction time, it can also be processed well manually - even in larger batches of up to approx. 10 kg. With mechanical foaming, the density and start-up time are reduced. UNIZELL PU Foam HR-AT is processed with Hardener Type 2 and is resistant to dilute acids, alkalis and water.
