Conventional polyols are essential components in the manufacturing of flexible polyurethane foam. These polyols serve as the backbone of the foam structure, reacting with isocyanates to form the polyurethane polymer matrix. Conventional polyols are typically polyether or polyester compounds with hydroxyl functional groups. They contribute to the foam’s flexibility, resilience, and load-bearing capacity. Conventional polyols can be tailored to meet specific foam performance requirements, such as density, firmness, and compression resistance.
