How a masterbatch supplier manufactures masterbatch?

All ingredients that are necessary to prepare a masterbatch are gathered and mixed together to form a homogenous mixture. The product thus formed is then subjected to shearing stress and converted in manageable pellets. To ensure a consistent mixture of all ingredients the mixture is taken through a series of devices such as strainers, kneaders and extrudes. This is done to ensure a thorough distribution of all ingredients throughout the masterbatch.

How masterbatch is applied?

Once the product leaves the masterbatch supplier, it can be used in many different ways. Some prefer to apply it directly to the stream using either volumetric dosing or graviametric dosing. The first method is economically more desirable compared to the later but it provides less control over calibration. The second process is more precise when it comes to calibration but setting up a graviametric plant is a costly affair. Getting the perfect result is difficult because even the slightest inconsistency in colour or thickness becomes readily apparent. To dull the effect, weaker dosing is done, gradually adding to the dosage as necessary. Masterbatches entirely take out the need for guesswork out of the equation. There is no need to experiment with the sample because a masterbatch supplier guarantees what to expect from the end result. 

A masterbatch supplier provides masterbatches to guarantee reliable colour and physical properties in a batch. Masterbatches offer cost savings compared to compound materials; it provides optimum distribution in the sample and saves on cleaning costs.
