1. A polyurethane and polyorganosiloxane foam material comprising at least one layer of cross-linked polyurethane/polyorganosiloxane foam including:
a) a polyurethane formed by reacting an isocyanate and a polyol;
b) a polyorganosiloxane having a cross-linkable functional group;
c) a polymerization catalyst;
d) a polymerization reaction initiator, said initiator being an isoprenoid compound; and
e) a polymerization reaction accelerator;
