Flexonal® PU 2688 is a two-component Polyurethane which cures at room temperature to a hard, foamed Duromer with a density of 45 kg/m³. The resting time after mixing is approx. 40 sec., followed by a rising time of approx. 150 sec. The resulting Foam is characterized by a very low density in combination with a closed-cell structure and thus very good insulating characteristics and fulfills Fire-Classification B2. The range of application lies in a wide temperature range from -50°C to +150°C.
Due to the high reactivity of this Foam System, rapid processing is necessary to achieve optimum results.
