    This is the first volume in the highly regarded Advances in Urethane Science and Technology series to be published by Rapra. This book presents reports on state-of-the-art developments in the field of urethane science, written by experts in their field. This volume is extensively illustrated and referenced. Table 4 shows the foaming formulations for rigid SPP-based polyurethane foams (SPP PU foams). Based on the results obtained from the first stage, the water content was fixed at 3% at the second stage to study the effect of isocyanate index and SPP percentage on the properties of SPP PU foams. The formulations are shown in Table by: The growth of the polyurethane foam market in North America is mainly driven by the increasing demand for flexible polyurethane foam from end-use industries in this region. Moreover, there is a significant demand for polyurethane foam for specific applications, such as automotive seating and customer needs. Background: Today, polyurethane foams can be found in various commercial products such as bedding, home furniture, automotive interiors and even construction materials. From a chemical point of view, polyurethane foams are made from a chemical reaction between a polyol (molecules with more than one hydroxyl group) and a diisocyanate in the Author: Gholamali Sharifishourabi, Xiao Yuan Chen, Tien-Binh Nguyen, Denis Rodrigue.
