The present invention is a mechanically frothed foam that is prepared from a polyurethane formulation that includes both an organo-metallic catalyst and a tertiary amine catalyst. Foams of the present invention have low density and good physical properties, which make them desirable for carpet applications.
L'invention concerne une mousse que l'on a fait écumer mécaniquement et qui est préparée à partir d'une formulation de polyuréthane qui comprend à la fois un catalyseur organométallique et un catalyseur d'amine tertiaire. Les mousses de la présente invention ont une faible densité et de bonnes propriétés physiques, ce qui les rend utiles pour la fabrication de tapis.
