agent has to be cleaved of the isocyanate shortly before or during the processing the polyols commonly used in the production of polyurethanes are also well known to those skilled in the art the most important classes are polyesterpolyols and polyetherpolyols which are basically polyester resp polyether chains terminated and optionally further substituted with isocyanate reactive hydroxyl groups e g the most commonly used polyetherpolyols are derived from ethylen oxide and or propylene oxide the polyurethane may contain further additives like blowing agents foam stabilisers chain extenders flame retardants fillers pigments etc known to those skilled in the art the present invention is further directed to the use of said low emission polyurethanes for use in car interiors the advantages and the important features of the present invention will be more apparent from the following examples polyol 1 is a 3500 mw polyether polyol oh no approx 38 available from elastogran as lupranol 3032 polyol 2 is a 4700 mw polyether polyol oh no approx 36 available from shell chemicals as caradol et 36 17 polyol 3 is a 6000 mw polyether polyol oh no approx 28 available from dow chemicals as voranol cp 6001 polyol 4 is a 6000 mw polyether polyol oh no approx 32 35 available from dow chemicals as voranol cp 1421 isocyanate 1 is toluene diisocyanate tdi mixture of 80 para and 20 ortho foam stabiliser 1 is a silicone available from crompton corp as niax rs 171.
