We use colored plastics on a daily basis but have you ever wondered how these plastics get the colors and the properties? In order to impart colors to the plastics, Masterbatch is used. Let us try to understand the difference between Masterbatch and other raw pigments. The dry and solid coloring substances are the pigments. The liquid form of pigment is used to make dyes, paints and colors. On the other hand, Masterbatch is the more advanced version of the pigments. The mixture of pigments and additives are heated and converted into carrier resin which again is cooled down and cut into granules. Both pigment and masterbatch are used in coloring plastic products. However, manufacturers tend to prefer masterbatch over others. Let us go through the various practical reasons to choose masterbatch and not raw pigments.

1.    SUPER HANDY AND MANAGEABLE: It is easier to store, move and manipulate masterbatches as they are available in pellet form. On the other hand, as the pigments are available only in powdered form which becomes difficult to manage.
2.    CONVENIENT: Color concentrates can be conveniently handled during the manufacturing process when we use masterbatch over pigments.

3.    SAFE: There is a high risk of pigments becoming airborne during the manufacturing process which could result in the contamination. On the other hand, the manufacturing of masterbatch doesn’t produce any harmful particles.
4.    EXCELLENT COLOR DISTRIBUTION: Masterbatches are created and designed for optimal dispersion in a polymer that enables the final product to have excellent color distribution. Pigments, on the other hand, do not disperse well.

5.    LESS PIGMENT USED: More plastic products will be created even with less quantity of masterbatch. However, the amount of pigment required for a product increases when raw pigments are used as they are in the powdered form.

6.    BETTER COLOR CONSISTENCY: Masterbatch offers excellent color consistency for products than raw pigments. The plastic products created using masterbatch tend to be more attractive and colorful.

7.    TIME AND COST SAVING: Additive ingredients in predetermined ratios can be included in a masterbatch. This reduces the chance of unwanted results during processing. In a way, it saves more time and cost effective.

8.    IMPARTS STRONG PROPERTIES: The masterbatch has the ability to deliver more advantageous traits such as flame retardancy, optical brightening, UV stability and chemical resistance. This helps limit the number of failed products during the process.

Clearly, masterbatch provides the most reliable and efficient way to color the polymers. There is also an option to have a better control over the opacity of a colored product with masterbatches. Due to the various advantages provided by additive masterbatches , they play a crucial role in imparting properties and colors to the plastic products. The easy laminated property, easily color transferable, used in various sectors, food packaging, durable, etc are so much look forward to. The Masterbatches also have the capacity to withstand harsh weather conditions. That is why, the masterbatch is the most desired material in the food packaging industry. The endless benefits of masterbatches have contributed to the plastic industry.
