Production of flexible polyurethane foams

Preparation of flexible, soft polyurethane foams having viscoelastic, structure-borne soundproofing properties, and polyoxyalkylene-polyol mixtures which can be used for this purpose

Preparation of flame-resistant soft polyurethane foams of reduced smoke density, and melamine/expandable graphite/polyether-polyol dispersions for this purpose

Preparation of polyurethane foams

Preparation of chlorofluorocarbon-free flexible polyurethane foams using diphenylmethane diisocyanate-based polyisocyanate mixtures containing urethane groups, and modified polyisocyanate mixtures of the type

Copolymers and their use as auxiliaries and/or additives in formulations for the preparation of polyisocyanate addition polymerization products

Process for the preparation of flexible polyurethane foams with viscoelastic, body-sound damping properties and the polyalkoxide-polyol blends for this process

Preparation of flexible polyurethane foams having low compressive strength and block polyoxypropylenepolyoxyethylenepolyol mixtures which can be used for this purpose

Preparation of CFC-free, highly resilient, flexible polyurethane foams, and diphenylmethane diisocyanate-based polyisocyanate mixtures modified by means of urethane groups which can be used for this purpose

Process for the preparation of fluorochlorohydrocarbon-free, low-density polyurethan soft foams and soft elastic polyurethan molding foams and polyisocyanate mixtures modified with urethan groups on diphenylmethane-diisocyanate base
