摘要：
Process for making a foam suitable as plant growth medium by reacting a polyisocyanate, a polyether polyol mixture and water at an isocyanate index of 90-150 wherein the polyol mixture used comprises at least 2 polyols and wherein the polyol mixture comprises less than 50 % by weight oxyethylene calculated on the weight of the polyol mixture. The polyurethane foam may be prepared from a polyisocyanate comprising diphenylmethane diisocyanate (MDI) and homologues thereof having an isocyanate functionality 5 of 3 or more wherein the amount of diisocyanate calculated on the total amount of the diisocyanates and the homologues is in the range of 20-80% or 25-70% by weight.
