| What Is Special Polyether Polyol SK-350D? |
Special polyether polyol SK-350D is used as an open-cell agent for high resilience molded foam and high resilience block foam. It improves the foam's openness and feel, and also enhances the demolding performance and surface quality of molded products.
Additionally, it serves as a base polyether for ultra-soft foams, allowing the foam to achieve a 25% ILD (Indentation Load Deflection) value of less than 40N. In MDI (Methylene Diphenyl Diisocyanate) formulation systems, special polyether polyol SK-350D can also be used as a base polyether for slow rebound foam, improving its feel and reducing the temperature sensitivity of the slow rebound sponge. |
