Semi-crystalline polymers can be fairly opaque if they have large spherulites. Clarifier act as nucleating agents cause crystallisation, starting from a large number of small spherulites, which give rise to less light scattering and greater light transmission. They enhance the aesthetics via enhanced clarity and surface gloss.
