In the field of Polyurethane Additives, Sucrose Series Rigid Foam Polyether Polyol and its derivatives (such as Sucrose Series Rigid Foam Polyether Polyol2) primarily serve as polyol raw materials, playing a crucial role in rigid polyurethane foam (Rigid PU Foam) systems.
However, they can also be classified as additive functional materials, as they not only participate in reactions but also influence foam properties and processing characteristics. Their functions can be summarized as follows:
Sucrose-based polyols provide abundant hydroxyl (–OH) functional groups that react with isocyanates to form polyurethane networks.
In rigid foam systems, they create highly crosslinked, dense three-dimensional skeletons, resulting in robust foam structures with high closed-cell content.
Modifying foam hardness, density, and compressive strength: Through molecular weight and functionality design, foam rigidity and mechanical properties can be precisely controlled.
Significantly impacting thermal stability and dimensional stability, making them suitable for applications like building insulation boards and refrigeration insulation materials.
The sucrose-derived structure in polyether polyol molecules enhances foam mixing uniformity and reaction activity, making the foam formation process more controllable.
This reduces risks of uneven foaming, coarse pores, or collapse, enhancing product consistency.
Within foam systems, sucrose-type polyols synergize with catalysts, surfactants (emulsifiers), flame retardants, and other additives to optimize closed-cell content, flame retardancy, and durability.
