Synthesis and Characterization of Flexible and Rigid Polyurethane Foam
Keywords:Polyurethanes, Flexible and rigid polyurethane foam, Cup Foaming
AbstractPolyurethanes are versatile materials used widely in many applications. Annual production of polyurethanes is increasing day by day. The most important application of polyurethane covering its major market is polyurethane foam. Flexible and rigid foams are two major types of polyurethane foam used widely. Flexible and rigid foam samples were synthesized on lab scale by cup foaming. All samples were characterized by finding density of each sample. Cream, gel and rise time were also estimated for each sample. The chemical compositions of all polyurethane foam samples were characterized by FTIR analysis.
