Incredible Possibilities of Adding Colours to Plastics

Dyes, pigments and optical brighteners are very necessary to make plastic products appealing. All of these are additives which are added to products during the production phase. Though using masterbatches is the primary way of adding colours to plastics, there are many ways how plastics can be coloured. We will take a look at the top three here now.

Salt & Pepper blends

For those mixers who lack metering units, cube blends are perfect. Like adding salt and pepper to a dish during preparation, this Masterbatch can be added mid-process. The mixture needs to be constantly stirred, failing to do which can lead to inconsistencies in colour.

Specialty compounds

Masterbatch Manufacturers in India have to tackle the issue of hues imparted by other additives which are mixed to products during the process of manufacturing. In addition to what masterbatches achieve, these specialty compounds are necessary to counter the effect of other hues.

Masterbatches

The most common form of adding colours to products is with the help of masterbatches. Most industries let Masterbatch Manufacturers in India know of their specific requirements which once designed are used in large batches. Masterbatches are the most economical method to colour plastics and can be provided in small volumes. Depending on the carrier selected, the same Masterbatch may be used to colour several different resins, or be chosen for maximum compatibility.

No matter what delivery method is used, most makers maintain a database of every formula devised to meet client requirements. This helps in speeding up the delivery process when subsequent demands are raised. Thanks to the fast and efficient processes Masterbatch Manufacturers in India have, you can manufacture your products in whatever colour you please.

How to Choose a Masterbatch Supplier

Masterbatches are used to improve the mechanical and aesthetic look and feel of plastic. Plastic by default is not available in the fancy colours your see in the final product, it has to be coloured and modified with additives. Usually, a plastic goods manufacturer approaches a masterbatch supplier for the modifiers and additives. Manufacturers prefer buying modifiers from a masterbatch supplier because compounded materials cost more than products manufactured using masterbatches.

Masterbatches have multiple uses; here are a couple of them.

To Make Products Visually Appealing

Unless artificially added, polymers are mostly colourless. It is necessary to add pigments to the batch to add colour to the final product. Depending on what you expect from the final product, masterbatches can either carry a translucent pigment or bright colour as necessary. Every masterbatch supplier may have a few variations in their product line up. Some choose to offer their products purely for the purpose of pigmentation.

To Enhance Physical Properties

Once, again, polymers used in making plastic products do not have what it takes to withstand relentless assault from the elements. UV wreaks havoc on the intrinsic properties of polymer and deteriorates its resistance to physical stress. UV stabilizers are added to the product in order to prevent the final product from being damaged by harmful UV rays.

What are master batches and where they are used?

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.
