Production Of PVC Defoaming Agent JY-925 By Suspension Method

Production Of PVC Defoaming Agent JY-925 By Suspension Method

JY925 defoamer is a high-efficiency polydimethylsiloxane defoamer successfully developed based on the characteristics of siloxane and the high-temperature performance of polyzyme. It has a stable, highly polymerized and cross-linked three-dimensional network branched structure, which is not easily emulsified or solubilized in the system and will not be decomposed in high-strength alkali. It also has the high-temperature foam-suppressing properties of polyether, resulting in long-lasting anti-foaming properties.
