Abstract
A polyurethane foam, a polyurethane/polyorganosiloxane foam, and a polyurethane foam polyurethane/polyorganosiloxane foam material are disclosed and described herein. The materials are formed in the presence of a polymerization reaction initiator (an isoprenoid compound), and a polymerization reaction accelerator. The polyurethane foam is formed from an isocyanate and a polyol. The polyurethane foam polyurethane/polyorganosiloxane foam material comprises the polyurethane foam which is cross-linked to the polyurethane backbone to a polyurethane/polyorganosiloxane foam. Optional gelling agents, emulsification control agents, reinforcement fillers, cross-linkers, reinforcement polymers, rubber reinforcers, silk proteins, emollients, stabilizers and colorants are also described. The polyurethane and polyurethane-polyorganosiloxane foam materials exhibit a high degree of flexibility, resilience and excellent impact absorption.
