PROCESS FOR THE PRODUCTION OF MEDIUM DENSITY DECORATIVE MOLDED FOAMS HAVING GOOD FIRE RETARDANT PROPERTIES WITH REDUCED MOLD TIMES, FIRE RETARDANT COMPOSITIONS AND FOAMS PRODUCED BY THIS PROCESS

Fire-resistant, medium density molded polyurethane foams which may be removed from a mold in substantially shorter times than previously possible are produced by the process of the present invention. These reduced de-mold times are achieved by including a solid flame retardant composition in the pol...

Beschreibung
Zusammenfassung:	Fire-resistant, medium density molded polyurethane foams which may be removed from a mold in substantially shorter times than previously possible are produced by the process of the present invention. These reduced de-mold times are achieved by including a solid flame retardant composition in the polyurethane foam forming composition. This solid flame retardant composition includes a melamine coated ammonium polyphosphate and zinc borate. La présente invention concerne un procédé de production de mousses de polyuréthane ignifugées de densité moyenne qui peuvent être retirés d'un moule en sensiblement moins de temps que ce qui était auparavant possible. Ces temps de démoulage réduits sont obtenus par l'inclusion dans la composition de formation de la mousse de polyuréthane d'une composition ignifuge solide. Cette composition ignifuge solide comprend un polyphosphate d'ammonium revêtu de mélamine et du borate de zinc.
