polyurethane rigid foam catalyst pc-8 in water-blown systems: a comprehensive overview
introduction polyurethane (pu) rigid foams are widely used in various applications, including insulation, packaging, and structural components, due to their excellent thermal insulation properties, high strength-to-weight ratio, and ease of processing. the production of these foams relies on a complex chemical reaction between isocyanates and polyols, typically in the presence of blowing agents, catalysts, surfactants, and other additives. water-blown systems represent a significant portion of the…
