Abstract

Procedure for obtaining soft, elastic, anti-inflammable polyurethane foam materials, by reaction of polyisocyanates with polyethers and crosslinking agents or chain extenders, with a molecular weight of 18 - 1,500, in the presence of propellants, catalysts and, if necessary, given other additives; characterized in that distilled toluenediisocyanate is used as polyisocyanate and those that contain at least two hydroxyl groups and have a molecular weight of 1,500 to 10,000 and in which, at least, 10% by weight of the existing hydroxyl groups are hydroxyl groups. primary, the reaction being carried out in the absence of foam stabilizers of the polyetherpolysiloxane type.
