What are masterbatches? Masterbatches are typically additional compounds that are largely used to add strength to polymers. They offer an easy and convenient way to add color and/or performance enhancing additives to natural or base polymers on their own plant. This method of using masterbatches is known to be cost effective and technically sound including reduced stock holding of compounded material, reduction in cleaning costs, optimum dispersion and hence reliable color and performance properties in the finished product. There are several advantages of using masterbatches such as:
- Low stock holding compared with pre-compounded materials
- Optimum dispersion of pigments/additives
- Dust free, no health and safety risks in comparison to undispersed fine powder pigments or additives
- Elimination of ‘trial and error’ development or formulation work, as this done by the masterbatch supplier who takes responsibility for color and consistency
- Reduction in purging/cleaning costs
To cater to the rising demand for plastic products, Masterbatch Manufacturers in India have been producing high quality masterbatches for further usage. A masterbatch is typically a solid concentrate of color and/or performance improving additives such as anti-static, UV stabilizer, metal deactivator, added to a base polymer to feature these attributes. It is generally supplied in granular form, either as pellets similar in size to most polymers or as miniature pellets, known as micro granules. Alternatively, masterbatch can be delivered in ‘rough cut’ form – a mixture of small shreds and chunks.
