Plastics are an important element in our daily lives and Masterbatches play an important role in the manufacturing of plastics across the world. Let’s start with understanding Masterbatches first. Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular phase. The main task of Masterbatches is that they allow the processor to color raw polymers in a cost effective way during the manufacturing of plastics.
There are typically two types of polymer resins are used. Carrier resin and dilution resin. Carrier resins are resins in which the pigments and/or additives are carried and which forms the masterbatch. While dilution resin makes up the bulk of the plastic processor’s finish product. To meet the rising demand for plastic products, there have been numerous Masterbatch Manufacturers in India.
Inorganic pigments are manufactured from natural raw materials and include fundamental types such as titanium dioxide, iron oxides and ultramarine blue. At the same time, it is important to notice that some types are not used due to their toxic levels. On the other hand, organic pigments are synthesized and possess lower heat stability than inorganics. One of the major drawbacks of this type of pigment system is that they are generally non-toxic and conform to legislation relating to food contact and safety.
