Surfactants

Surfactants are typically available as liquids or powders that can be added to plastics to modify surface properties. These substances function by reducing surface tension, allowing for better wetting, dispersion, and emulsification. Key features of surfactants include their ability to enhance compatibility between different materials, improve processing efficiency, and provide anti-static properties. Used in packaging, compounding, medical devices, and conductive plastics. 

Alternatives include bio-based and silicone-based surfactants. Sub-types include anionic, cationic, non-ionic, and amphoteric surfactants.
