Abstract: The invention relates to a process for the preparation of chlorofluorocarbon-free (CFC-free), elastomeric, semi-rigid or rigid mouldings containing urethane groups or urethane and urea groups and having 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) at least one microporous activated charcoal and/or a microporous carbon molecular sieve, which preferably has a mean pore diameter with more than 40% in the range from 0.3 to 3 nm, a pore volume of from 0.20 to 1.4 ml/g and a BET surface area of from 500 to 2500 m /g or greater, and optionally further additives and g) auxiliaries, in a closed mould with compaction.

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: A process for the production of fluorochlorocarbon-free, urethane-containing, softelastic, semirigid or rigid moldings having a cellular core and a compacted peripheral zone and an essentially pore-free, smooth surface involves reacting a) an organic and/or modified organic polyisocyanate with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and, if desired, c) a low-molecular-weight chain extender and/or cross linking agent, in the presence of d) a blowing agent, e) a catalyst, f) at least one amorphous, microporous silica gel which preferably has a mean pore diameter with a frequency of occurrence of more than 40 % in the range from 0.1 to 10 nm, a pore volume of from 0.15 to 1.8 ml/g and a BET surface area of from 200 to 900 m2/g, and, if desired, further additives and g) assistants, in a closed mold with compaction.
