Silicone-free Defoamer for Water-soluble Polymeric Materials
SY-915
SUNY SY-915 is a modified polyether ester defoamer. Unlike conventional polyether defoamers, it demonstrates superior defoaming and foam suppression performance. It is applicable for foam control in white water during the paper sheet formation stage of papermaking, and in dissolution processes of water-soluble polymeric materials.
