Anti-fog masterbatches are specialized formulations designed to prevent the formation of fog or water droplets on the surface of plastic films, sheets, or products. Fogging occurs due to the condensation of water vapor, which forms droplets on the surface, reducing visibility and impairing product functionality. Anti-fog masterbatches work by modifying the surface tension of the plastic, causing the water droplets to spread into a thin, uniform layer rather than forming beads.
