  • the resins contain small amounts of adhesion-promoting substances, such as silanes.
  • film-forming thermoplastic binders are used occasionally for the binding of flexible insulating elements.

These substances are referred to collectively as additives or as lubricants.

Due to the superimposed upsetting movements, there is an intense unfolding of the mineral fibers. Here, the core areas of the original primary mineral fiber web can be seen as narrow web-like structures between which mineral fibers are in rolled, but at least lesser density. These ridge-like densities extend in a seemingly horizontal position across the folded mineral fiber web. After solidification of the mostly used thermosetting resin mixtures with the aid of hot air, the unfolded structure is fixed.
