    Abstract: Polyurethane foam is made by reacting an isocyanate with a polyol and foam forming ingredients in the presence of a reactive double bond component, particularly an acrylate, to give a foamed body which is subjected to radical initiated cross-linking with the reactive double bond component. In one embodiment the foam-formation and cross-linking are carried out in parallel, and an organic peroxide may be included as a cross-linking initiator. In another embodiment the cross-linking is carried out after foam-formation preferably using E-beam activation. In this case different formulations, using polyether polyol with MW greater than 1500, non MDI, polymer modified polyol or non HR formulations are used. In this case also, it is also possible to use selected formulations which give at least 10% hardness increase without scorching, or which, by controlled use of 0.1 to 10 parts double bond component give low density foams with more than 4 parts water as foaming agent, without scorching.

    Abstract: A viscoelastic foam system is provided having an amine-based polyoxypropylene extended polyol to impart strength, recoverability and endurance to the foam, and an appropriately selected non-amine-based polyol to provide flexibility to the foam. The combination of amine-based propylene oxide extended polyol and non-amine-based polyol provides a viscoelastic semi-rigid foam with excellent impact and recovery properties, recovering to substantially 100 % of its initial volume and shape following an impact, yet with sufficient rigidity and stiffness so that it is effective at absorbing multiple impacts. A method of making the above viscoelastic foam is also provided.
