Additive Masterbatch
Additive Masterbatch is a concentrated mixture of functional additives incorporated into a polymer carrier resin. These additives are used to enhance or modify the physical properties, processing behavior, or performance characteristics of the final plastic product. Unlike color masterbatches, which primarily focus on imparting color, additive masterbatches are used to impart additional functional benefits to plastics.
Additive masterbatches can contain a wide range of chemicals designed to improve the properties of plastic. Common types of additives include:
UV Stabilizers: Protect the plastic from degradation due to ultraviolet (UV) light exposure. UV stabilizers prevent discoloration, cracking, and embrittlement caused by prolonged exposure to sunlight. These are essential in outdoor products such as garden furniture, agricultural films, and automotive parts.
Antioxidants: Prevent oxidation in plastics, especially during processing or prolonged use at high temperatures. This helps to maintain the material’s mechanical properties and appearance, particularly in polyolefins and other thermoplastics.
Advantages of Additive Masterbatch
Versatility: Additive masterbatches can be designed to meet specific needs, whether it’s for enhancing performance, improving processing, or providing additional protection.
Simplifies Formulation: Instead of directly adding individual additives, manufacturers can use pre-formulated additive masterbatches to achieve the desired effect, reducing handling complexity.
Enhances Product Durability: Additives like UV stabilizers and antioxidants can significantly enhance the lifespan and durability of plastic products exposed to harsh environmental conditions.
