Diese Bestandteile können ebenso wie bei Beispiel 1 aufgeschäumt und vermischt sowie vor Erhärtung des Schaumes verspritzt und anschließend kondensiert Und vulkanisiert werden. Die sich hierbei ergebenden Mehrkomponentenschäume sind besonders öl- und fettbeständig und zeigen eine hohe Widerstandsfestigkeit gegjn Wärme-, Sauerstoff- und Lichteinwirkung. As in Example 1, these constituents can be foamed and mixed and before hardening of the foam splashed and then condensed And get vulcanized. The resulting multicomponent foams are particularly oil and fat-resistant and show a high resistance to heat, oxygen and light.
