Optical Brightener Masterbatches, also known as clarifying agents or glassifying agents for polypropylene, enhance the crystallization rate and increase the overall crystallinity of the polymer. As a result, they significantly improve the transparency of injection-molded parts, increase dimensional stability, reduce injection molding cycle times, minimize unwanted crystallization, and eliminate haze while enhancing the gloss and surface finish of the final product.

An additive masterbatch is a polymer-based material which is added to the raw materials of a plastic product during production to create or enhance specific properties in the final product. For example, a clarifying masterbatch is considered an additive masterbatch. In the plastics manufacturing industry, different properties are required depending on the end-use product. For instance, if a product is meant to be used outdoors and exposed to sunlight for long periods, an Anti-UV masterbatch should be added during production to improve its resistance against ultraviolet (UV) radiation and extend its lifespan. Other common types of additive masterbatches include white, black, anti-block, anti-static, brightening, anti-shrink, antioxidant, and moisture absorber masterbatches.
