Overview of Oh Polymer Hydroxy Terminated Silicone Oil107 for RTV Rubber Material
Polymer surfactants, also known as polymeric surfactants or amphiphilic polymers, are high-molecular-weight compounds that combine the properties of traditional low-molecular-weight surfactants with the unique features of polymers. Unlike small molecule surfactants, polymer surfactants offer enhanced stability, improved solubility, and the ability to form more complex structures such as micelles, hydrogels, and vesicles. These macromolecules find applications across a wide range of industries due to their tailored structures and tunable properties, which allow for precise control over interfacial behavior and solution rheology.
