Process for making open celled (semi-) rigid polyurethane foams using as cell opening agent a fatty acid or a fatty acid amine or a fatty acid amide or a fatty acid ester.

The invention deals with a process for the preparation of molded articles having a compressed peripheral zone and a cellular core, such as for example, flexible elastic shoe soles having a density of from 0.4 to 1.0 g/cm3, comprising reacting; a) organic and/or modified organic polyisocyanates with; b) at least one higher molecular weight compound having at least reactive hydrogen atoms and with o...

It has been found that 1,1,1,2-tetrafluoroethane (HFC-134a) may be used alone or in combination with water as blowing agents in flexible integral skin foams. Foa ms prepared using HFC-134a alone or in combination with water exhibit physical characteristi cs such as resistance to abrasion and cracking on flex comparable to conventional chlorinat ed fluorocarbon blown foams. The foams of the present...

It was found that a combination of thermoplastic microspheres containing a volat ile hydrocarbon and water could be used as effective co-blowing/density reducing age nts in low density, integral skin polyurethane foams.

An azeotropic compsn. comprises: (a) 65-81 wt.%1,1,1,3,3-pentafluoropropane; and (b) 19-35 wt.% 2-methyl butane, where the compsn. has a b.pt. of about 7 deg C at 1 atmos.. Also claimed is the prodn. of polyurethane foam comprising reacting a polyisocyanate with an isocyanate reactive material in the presence of the above azeotropic compsn..

The run-flat tire (10) of this invention includes a pair of bead regions (20), a crown region (14) with a tread (12) and a tread reinforcing package (80) including a cap ply and self supporting sidewalls (4) between each bead region and the crown region.
