Light diffusion masterbatch refers to a class of microparticles with unique optical properties that scatter light and change its color and brightness. This kind of masterbatch is widely used in cosmetics, food, plastics, coatings, inks and other fields, and can provide special visual effects for products. At the same time, light-scattering masterbatches are also used in scientific research, such as in nanotechnology, material science, biomedicine and other fields.
