Beschreibung
Zusammenfassung:	Disclosed are polyurethane-foam forming compositions, rigid polyurethane foams and methods for their production, as well as to composite articles comprising such foams sandwiched between facer substrates, including use of such composite elements for side-wall and/or roof insulating elements for refrigerated tractor trailers. The rigid polyurethane foams are produced from an isocyanate-reactive composition comprising: (1) a polyol blend; (2) a hydrochlorofluoroolefin; and (3) a tertiary amine catalyst composition. 公开了聚氨酯泡沫形成组合物、硬质聚氨酯泡沫及其制备方法，以及包含夹在饰面基材之间的这类泡沫的复合制品，包括这类复合元件用于冷藏牵引拖车的侧壁/或车顶隔热元件的用途。硬质聚氨酯泡沫由异氰酸酯反应性组合物制备，所述异氰酸酯反应性组合物包含：(1)多元醇共混物；(2)氢氯氟烯烃；和(3)叔胺催化剂组合物。
