Plastics and polymers inherently possess the characteristics that define their utility—flexibility, durability, and resistance to environmental factors. However, these materials often require the inclusion of various additives to optimize their properties. Additives such as plasticizers, stabilizers, colorants, flame retardants, and fillers play a crucial role in enhancing performance, processing, and aesthetics. For instance, plasticizers are used to increase flexibility, while stabilizers help improve UV resistance and prolong product lifespan.
