Abstract (en)

[origin: DE10225793A1] Polyurethane elastomer adhesively bonded with polytetrafluoroethylene by means of a reactive melt adhesive is new Independent claims are included for: (1) a method for preparation of the polyurethane (PU) elastomer involving application of ground reactive adhesive melt (GRAM) based on encapsulated isocyanates to the elastomer surface to be bonded and/or to the surface of a polytetrafluoroethylene (PTFE) film, melting of the GRAM at 30-90degreesC, fixing of this to the part to be bonded, activation of the GRAM by heating to a temperature exceeding 100degreesC, and by reaction of the GRAM the PTFE is bonded to the Polyurethane elastomer; (2) an elastic support containing the PU elastomer; (3) an automobile or freight vehicle containing the elastic support.
