Amine Catalysts for Low-Density Soft Polyurethane Foams: An In-depth Guide

Introduction Low-density soft polyurethane (PU) foams are widely used in various applications, including furniture, bedding, automotive interiors, and packaging. The production of these foams relies heavily on the use of catalysts to control the reaction between isocyanates and polyols, promoting urethane bond formation and CO2 generation for foam expansion. Among the catalysts used, amine-based catalysts…
