Have you ever wondered how plastics get their vibrant colors and enhanced properties? The answer lies in masterbatch—a concentrated mixture of pigments and additives used in polymer production. However, traditional masterbatch solutions pose significant environmental challenges. In this post, you'll learn about sustainable and eco-friendly masterbatch options that reduce environmental impact while maintaining product performance.
Masterbatch is a concentrated mixture of pigments and additives encapsulated during a heat process into a carrier resin. This carrier resin allows easy dosing into raw polymer materials during manufacturing. Essentially, masterbatch acts as a colorant or additive provider, enhancing polymers without altering their fundamental properties.
Components of Masterbatch
Carrier Resin: The base material that holds pigments and additives, compatible with the polymer being processed.
Pigments: Provide color to the final product.
Additives: Improve or modify polymer properties, such as UV resistance or flame retardancy.
Types of Masterbatch
Color MasterbatchThis type imparts color to plastic products. It contains pigments or dyes dispersed uniformly in the carrier resin, ensuring consistent color and ease of use in manufacturing.
Additive MasterbatchAdditive masterbatch contains functional additives rather than colorants. Examples include UV stabilizers, antioxidants, antistatic agents, and flame retardants. These additives enhance performance and durability.
Filler MasterbatchFiller masterbatch incorporates fillers like calcium carbonate or talc to reduce cost, improve mechanical properties, or modify weight.
