In the present day of globalisation, getting access to coloured plastic products is a no big deal, which does not let us comprehend about its production intricacy. A part of all the work that goes into the production of aesthetically pleasing plastics, is the colour. The pigment of a colour can be a masterbatch or a raw powder. Little consideration is given to understand the difference between a masterbatch and the archaic method of colouring with raw pigments, which could be a huge know-how for someone who is in production of plastics.
Before understanding the difference, one must be aware of what is a masterbatch and a raw pigment. Albeit related, masterbatches and pigments are largely mistaken to be synonymous. Masterbatch is an advanced pigment, featuring specific concentrations of colours and additives encapsulated by a polymer. While at it, one needs ensure the compatibility of a masterbatch with the main plastic. Only after which, a masterbatch is optimally diffused through a carrier material. A raw pigment, alternatively, refers to a dry, solid colouring substance, which is mixed with water to create a consistency of a paint, ink or a dye, as per the requirement.
The most essential benefit of a masterbatch over a powdered pigment is of dispersion of the carrier resin. The raw pigment does not diffuse well on its own and is very likely to be distributed unevenly throughout the product. However, a masterbatch is intricately planned and engineered to create optimal dispersion in a polymer pattern, which allows for uniform dissemination of the pigment.
Masterbatch can contain additive ingredients for traits such as UV stability, antioxidants, flame retardancy or optical brightening, limiting the number of feeds into your process.. These are included in predetermined ratios, decreasing the chance of discrepancy during the process.
