Emulsifiers

Emulsifiers are typically clear, viscous liquids or fine powders that help stabilize mixtures of immiscible substances, such as oil and water, in plastics. They function by reducing the surface tension between the different phases, allowing them to blend more uniformly. Key features of emulsifiers include their ability to enhance the dispersion of additives, improve the consistency of the final product, and prevent separation during processing. They are particularly suitable for applications in food packaging, medical devices, and automotive parts. 

Alternatives to emulsifiers include surfactants and stabilizers. Sub-types include anionic, cationic, and nonionic emulsifiers.
