Abstract:
The present invention relates to a method for cutting rigid foams, especially slabstock P(M)I foams. A method is provided here, by means of which it is possible to cut these rigid foams even in relatively high layer thicknesses of, for example, more than 3 mm, without material loss, which is produced in relevant amounts, for example, in the course of sawing as a result of the sawdust formed.
