1. Förfarande för framställning av elastiska skumraaterial baserade pä en melamin/formaldehyd-kondensationsprodukt genom skumning av en vattenlösning eller-dispersion, som innehäller ett melamin/formaldehydförkondensat, en emulgator, ett flyktigt jäsmedel och en härdare samt, om sä önskas, konventionella tiilsatsämnen, varefter skummet härdas, kännetecknat därav, att a) koncentrationen av förkondensatet i blandningen inne-hällandeförkondensat och vatten (utan tiilsatsämnen) väljs sä, att den ligger ovanför brytningspunkten för den första derivaten av kurvan som erhälls dä man under bibehällande av alla andra förhällanden i blandningen av förkondensat och vatten konstanta varierar vattenmängden och sedan uppritar en kurva över blandningens viskositet (mätt vid jäsmedlets koktemperatur under förhällanden, som räder vid början av skumningsförloppet) som funktion av för-kondensatkoncentrationen, varvid dock koncentrationen av förkondensatet ej fär vara högre än värdet, som i den beskrivna kurvan motsvarar en viskositet av 5000 dPas, att b) under skumningsförloppet fram tili tidpunkten dä skummet nätt 80 % av den maximalt uppnäbara stighöjden, viskositeten hos vattenlösningen eller -dispersionen ä ena sidan ej fär underskrida det värde, som i den under a) beskrivna kurvan motsvarar den där definierade lägsta koncentrationen och ä andra sidan ej fär över-stiga 6000 dPas, och att c) efter uppnäende av den under b) definierade tidpunkten viskositeten genom härdningen av förkondensatet överstiger 10 000 dPas inom 8 minuter, varvid i b) och c) viskotiteterna alltid mäts i ett jäsmedel-fritt parallellsystem.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att skummaterialet uppvärms 1-180 minuter vid en temperatur av 120-300°C, varvid vatten, jäsmedel och formalde-hyd väsentligen avlägsnas och en ytterligare härdning sker.
