Abstract

Composite articles comprise a foam based on a polyisocyanurate produced by reacting an isocyanate with an isocyanate-reactive compound (I) having a hydroxyl number of no more than 120 mg KOH/g. An Independent claim is also included for production of such articles by reacting an isocyanate with (I) and optionally a chain extender and/or crosslinking agent in the presence of a propellant, a catalyst and optionally a flame retardant and/or additives.
