Silicone Oil is a non-hydrolyzed silicone surfactant with medium and high activity,used for soft polyurethane foaming.It is suitable for horizontal foaning ranging from low desity to medium desity. PL-5889 can be compatible with polyol mixtures and Various additives,to form a uniform nucleation system,the foam can form a fine and uniforma cell structure.meanwhile,it can ensure the normal foam permeability and provide high processing tolerance.
