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.
