Beschreibung
Zusammenfassung:	Polymeric microspheres may be included in polyisocyanurate/polyurethane foam compositions. An exothermic foaming process and/or the application of heat during the foaming process may cause the polymeric microspheres to expand in diameter. The expanded polymeric microspheres may improve the structural properties and/or the insulating properties (e.g., R-value) of the resultant foamed PIR/PUR composition, especially an open-cell structure. Des microsphères polymères peuvent être incluses dans des compositions de mousse de polyisocyanurate/polyuréthane. Un processus de moussage exothermique et/ou l'application de chaleur pendant le processus de moussage peuvent amener les microsphères polymères à se dilater en diamètre. Les microsphères polymères expansées peuvent améliorer les propriétés structurales et/ou les propriétés isolantes (par exemple, valeur R) de la composition PIR/PUR expansée résultante, en particulier une structure à cellules ouvertes.
