PRODUCTION OF PU FOAMS USING RECYCLED POLYOLS

A process for producing polyurethane foams is developed by reacting at least one polyol component that includes recycled polyol with at least one isocyanate component, in the presence of one or more catalysts that catalyse the isocyanate-polyol and/or isocyanate-water and/or isocyanate trimerization...

Beschreibung
Zusammenfassung:	A process for producing polyurethane foams is developed by reacting at least one polyol component that includes recycled polyol with at least one isocyanate component, in the presence of one or more catalysts that catalyse the isocyanate-polyol and/or isocyanate-water and/or isocyanate trimerization reactions, at least one foam stabilizer and optionally one or more chemical or physical blowing agents. The polydispersity of the respective recycled polyol is
