e without limitation of volume by a twin belt press mold or the like the result is a nonwoven with an extremely low density the density primarily depends on the amount of blowing agent introduced into the binder in addition the foaming may be limited in volume terms for example the volume can be limited by the production method to define densities and molding with zone by zone differences e g for car doors in addition when thermosets are used or used concomitantly the molding produced by expansion pressure in the hot mold can be fixed directly then in the mold the stresses resulting as a consequence of the foaming process do produce some degree of reorientation and stretching of the long fibers 1 as a result the long fibers 1 may be drawn into the foam droplets 2 this can increase the strength of the bond at the coupling sites 3 in other words the nonwoven is a mixture of long fibers 1 that are only partially bound together through small foam bodies 2 i e binder droplets formed as nodal points to produce a nonwoven of low density when forming the nonwoven it is possible to insert the small foam bodies.
