Description
Mineral oil-based defoamers are formulated using mineral oils such as cycloparaffinic mineral oil, straight-chain mineral oil, and paraffin wax as the base oils, supplemented by specially modified vegetable oils as auxiliary oils, and combined with various dispersants and other ingredients through a unique emulsification process. O/O-type emulsion defoamer.
Due to its diverse base oil composition, different directions of auxiliary oil modification, complementary functions of dispersants, and excellent high-temperature resistance, it exhibits strong acid-alkali resistance, superior thermal stability, and does not cause color migration. As a result, it finds wide application in certain specific industries or scenarios.
