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 floor 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. L'invention concerne des compositions de formation de mousses polyuréthanes, des mousses polyuréthanes rigides et des procédés pour leur production, ainsi que des articles composites comprenant de telles mousses prises en sandwich entre des substrats de parement, y compris l'utilisation de tels éléments composites pour des éléments d'isolation de plancher de semi-remorques réfrigérés. Les mousses polyuréthanes rigides sont produites à partir d'une composition réactive à l'isocyanate comprenant : (1) un mélange de polyols ; (2) une hydrochlorofluoroléfine ; et (3) une composition de catalyseur amine tertiaire.
