The Difference Between General And Specialized Colour Masterbatch

There are many drawbacks to general colour masterbatches. In fact, the 'general' range of general masterbatches is very narrow, and the technical specifications and economic efficiency are poor.

Specialized Masterbatch

These are masterbatches made from the same plastic as the carrier, according to the type of plastic specified by the user for the product. For example, PP masterbatch and ABS masterbatch use PP and ABS as carriers respectively.

General Colour Masterbatch

General purpose masterbatch: A certain resin (often PE with a low melting point) is also used as a carrier, but it can be used for colouring other resins than the carrier resin.

General colour masterbatch is relatively simple and convenient, but has many disadvantages and it is recommended that you use a specialized masterbatch.

Why do many companies not produce general masterbatches?

The majority of regular international masterbatch companies do not generally produce general masterbatches.

There are many disadvantages to general masterbatches. In fact, the 'general' range of general masterbatches is very narrow, and the technical indicators and economic benefits are poor, as shown by

  1. Poor predictability of colouring effect

Colour masterbatch is used for colouring, and the pigments of general colour masterbatch will show different colours in different plastics, so the foreseeability of the colouring effect is poor.

  1. Affects other properties of plastic products

In particular, it affects the strength, the product is easily deformed and distorted, more obvious for engineering plastics.

  1. Higher cost

In order to be 'general', general colour masterbatches often use pigments with a high heat resistance rating, resulting in waste.

 

Can masterbatches be used for colouring, but also for flame retardancy, brightening, anti-static, anti-oxidation and UV resistance?

A masterbatch can have some of these functions at the same time, if the factory requires it.

Sometimes, although not requested by the customer, the colour masterbatch company may suggest some additives, such as brightening agents, to the masterbatch, depending on the needs of the product. This, of course, increases the cost of the product.
