Master Batch and Plastic Raw Material: Increased Appeal

by Deepika Olive SEO Executive
Master batch or MB is an additive which comes in solid or liquid state and is used for plastic coloring. It is a concentrated mixture of pigments and additives abridged during a heat process into a carrier resin which is then cooled and cut into granular shapes. Master batch helps the processor in coloring the raw polymer economically during the manufacturing process. In comparison to other fully compounded material, Master batch needs more storage space hence increasing the lead times and more affordable.

How Master batch manufactures in India produce them?

  1. Weighing.
  2. Mixing.
  3. Twin screw extruding.
  4. Cutting and cooling.
  5. Sieving.
  6. Bagging.

Many manufacturers go with Master batch instead of raw pigment:

In our day-to-day lives, we usually come in contact with colored plastics. Because pigments are dry, solid coloring substances that are mixed with a liquid to produce a paint, ink or dye. Whereas master batches are more advanced with specific concentrations of pigments and additives encapsulated by a polymer.

  1. Master batch comes in pallet form making it less messy to store, move and manipulate.
  2. It is easier to handle color concentrates while manufacturing the product.
  3. Pigment has low dispersion quality and master batch is designed in such a way that it disperses optimally in a polymer matrix and hence the result is appealing color distribution.
  4. The binding agent of master batch can be matched to the polymer used in the product and it improves the melt processing.
  5. Master batch offers best color consistency of products from lot to lot.

Plastic raw materials are produced using different kinds of matter over the years. Plastics are organic materials which contains carbon, hydrogen, nitrogen, chlorine and sulfur. Plastic is produced by two processes:

  • Polymerization
  • Polycondensation

Both the processes require a specific catalysts. In Polymerization, monomers are required such as ethylene and propylene are linked together to form long polymer chains. 

There are many different types of plastic which can be grouped in two polymer families:

  1. Thermoplastic: These types of polymer softens on heating and harden again after cooling.
  2. Thermosets: These type of polymer never soften once they have been modeled.

Plastic when colored using a master batch has more consistency and accuracy. It has controlled opacity or transparency which makes them more appealing. Predetermined ratios of additives in a master batch makes them highly accurate. While producing large orders of plastics with master batch it makes the final result more consistent. Due to the binding agents of master batch, melting process also improves. When pigments can be airborne during processing and hence contaminate the adjacent manufacturing lines, master batch can be stored for longer times.

So if you're going to order in bulk for colored plastics, you should choose the one produced with master batch instead of raw pigments. It will be long lasting and more appealing.
