Abstract: The invention relates to a process for the production of soft-elastic mouldings which contain urethane groups and are free from chlorofluorocarbons (CFCs), and have a cellular core and a compacted peripheral zone with an essentially pore-free, smooth surface, by reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents, e) catalysts, f) crystalline, microporous molecular sieves having a cavity diameter and cavity entrance aperture of less than 1.3 nm, comprising metal oxides or metal phosphates and optionally further additives, and g) assistants, in a closed mould with compaction, expediently by reaction injection moulding (RIM).

Abstract: An integral foam material (I) based on polyurethane contains a comminuted microcellular polyisocyanate - poly-addition product (II). An Independent claim is included for a process for the production of the foam (I) by mixing isocyanate, isocyanate reactive compounds, propellant and optionally catalyst and/or conventional processing aids and/or additives in the presence of 0.1-40 wt.% of a comminuted, microcellular polyisocyanate-polyaddition product (II).
