摘要

Composition suitable for the manufacture of polyurethane foams, comprising at least one polyurethane component, at least one propellant, a catalyst which catalyses the formation of a urea or isocyanate bond and which contains a silicon-containing foam stabiliser, it contains as a fuel at least one unsaturated hydrocarbon or unsaturated hydrocarbon and at least one surfactant TD with no silicon atom and a HLB value of less than 10, the proportion of the sum of the surfactant TD in the composition of 0, 05 and 20 mass components per 100 mass components are polyol components,and containing the composition as Tensid TD Cocoamide DEA, Isotridecanol or Isononanol.
