OPE-108 (octylphenol ethoxylate) is a high-performance nonionic surfactant with CAS number 121809-82-3, appearing as a colorless to light yellow transparent liquid. Its core advantage lies in its excellent emulsifying, wetting, and dispersing capabilities, along with resistance to acids, alkalis, and hard water, maintaining stable surface activity under demanding process conditions. Furthermore, this product exhibits low foaming tendency, is easy to handle, and shows good compatibility with various resin systems and additive systems, making it a widely adopted general-purpose additive in industrial formulations.
From a functional perspective, OPE-108 primarily serves five roles in various processes: as an emulsifier, effectively reducing oil-water interfacial tension to form stable emulsions; as a wetting agent, significantly improving the spreading and penetration of liquids on solid substrates; as a dispersant, facilitating the uniform distribution and stable suspension of pigments and fillers in media; as a lubricant, reducing melt viscosity and improving processing flowability and mold release; and as a softening agent/leveling agent, imparting a smooth and delicate feel to material surfaces. These functions make it highly flexible and irreplaceable in cross-industry applications.
