SUNY Polyether-based Defoamer Antifoam for Paper Making
SY-415
The antifoam SY-415 a modification of polyoxypropylene-polyoxyethylene block copolymers synthesized in the presence of initiators. Unlike conventional polyether defoamers, it exhibits significantly enhanced defoaming and foam-suppressing capabilities.
