This invention relates to flexible foams and flexible molded foams prepared from an isocyanate component comprising an allophanate-modified diphenylmethane diisocyanate. The present invention also relates to processes for the production of these flexible foams and flexible molded foams.

Flexible foams and flexible molded foams based on allophanate-modified

A novel isocyanate reactive mixture is described which allows for the preparation of energy absorbing foams which meet Chrysler specification DC-640. The reactive mixture contains a) a filled polyol, b) a propylene oxide adduct of a mono-, di-, or trialkanolamine and c) a polyoxyalkylene polyamine. Foams prepared from the reactive mixture are also described.

Water blown, energy absorbing foams

The present invention is directed to an isocyanate reactive mixture of specified amounts of a) a polyether polyol having a hydroxyl functionality of from 4 to 8 and having a hydroxyl number of from about 300 to about 450, b) a polyether polyol having a hydroxyl functionality of from 4 to 8 and having a hydroxyl number of from about 50 to about 200, and wherein at least 75% of the hydroxyl groups are primary hydroxyl groups, c) an adduct of a mono-, di-, or trialkanolamine and propylene oxide, said adduct having a hydroxyl number of from about 100 to about 800, and d) a polyoxyalkylene polyamine having a molecular weight of from about 2000 to about 5000, and containing from 2 to 3 primary amino groups. The invention is also directed to water-blown, energy absorbing foams made from the isocyanate reactive mixture.

The present invention is directed to an isocyanate reactive mixture and the flexible polyurethane foam produced therefrom. The reactive mixture contains specific filled polyols, water, a catalyst for the reaction between an isocyanate group and a hydroxyl group, and a specific N-hydroxyalkyl quaternary ammonium salt. The isocyanate used is toluene diisocyanate.

System for the production of toluene diisocyanate based flexible foams

The present invention is directed to a reactive mixture for use in preparing a flexible polyurethane foam and to the foams produced therefrom. The reactive mixture broadly comprises an isocyanate reactive composition comprising:
