Abstract:
The present invention relates to a method for producing flexible polyurethane foams based on polyoxymethylene-polyoxyalkylene block copolymers. The invention also relates to the use of the flexible polyurethane foams thus produced and their use for producing furniture upholstery, textile inlays, mattresses, automobile seats, headrests, armrests, sponges, foam sheets for use in automobile parts such as roof linings, door panel upholstery, seat covers and technical components. The invention finally relates to a two-component system for producing flexible polyurethane foams.
