Silicone Antifoam (DY-ET121)

We are one the popular China based Silicone Antifoam Manufacturers, Exporters and suppliers. Silicone Antifoam (DY-ET121) is a solution that prevents foam from forming; however, the generic term "antifoam" is often used to describe both types of foam-control products. It doesn’t just prevent foaming but also causes existing foam to collapse quickly. Silicone Antifoam (DY-ET121) is used to break the foam because it is stabilized by the surface elasticity and surface viscosity of its film, which makes it difficult to break it down. As the renowned Silicone Based Antifoam Agent Supplier, we offer Silicone Antifoam (DY-ET121) that carries the properties such as low surface tension, interfacial properties and lack of foam-stabilization, which make the foam wall to thin and collapse.

Details : This is a kind of modified polydimethyl siloxane with polypropylene oxide.

Usage :
