Masterbatch basic knowledge

How to distinguish between universal color masterbatch and special color masterbatch?
Universal color masterbatch
A resin (often a low melting point PE) is also used as a carrier, but it can be applied to the coloration of other resins than its carrier resin.
The universal color masterbatch is relatively simple and convenient, but has many disadvantages. It is recommended that you use a special color masterbatch.
Dedicated color master
It is a color master made of the same plastic as the carrier according to the plastic type specified by the user for the product. For example, PP color masterbatch and ABS color masterbatch respectively use PP and ABS as carriers.
Why do many companies not produce universal color masterbatches?
Most formal color masterbatch companies in the world generally do not produce universal color masterbatches. There are many disadvantages to the universal color masterbatch. In fact, the universal range of universal color masterbatch is very narrow, and the technical indicators and economic benefits are also poor. The specific performance is as follows:
1. The coloring effect is poorly predictable. The color masterbatch is used for coloring, and the pigment of the universal color masterbatch exhibits different colors in different plastics, so the coloring effect is less predictable.
2. Affect other properties of plastic products. In particular, it affects the strength, and the product is easily deformed and twisted, which is more obvious to engineering plastics.
3. The cost is higher. In order to be versatile, the universal color masterbatch often uses a pigment with a higher heat resistance level, resulting in waste.
In addition to coloring, can the color masterbatch also have the functions of flame retardant, brightening, antistatic, anti-oxidation and anti-ultraviolet rays?
The color masterbatch can have several of these functions at the same time, if the factory asks for this.
Sometimes, although the customer does not ask for it, the color master company will advise the user to add some additives depending on the needs of the product, such as adding certain additives such as brighteners to the color masterbatch. Of course, this will increase the cost of the product.
What is the heat resistance of the color masterbatch?
The heat resistance grade of the special color masterbatch is generally compatible with the plastic used for the product, and can be used with confidence at normal temperature. Only in the following cases will cause different degrees of discoloration, one is that the temperature is beyond the normal range, and the other is that the downtime is too long.

What is the difference between granulation coloring and color mastering?
Masterbatch coloring has the following advantages over granulation coloring:
1. Coloring and product processing are completed at one time, avoiding the heating process of granulation coloring on plastics, which is beneficial to the quality of plastic products.
2. The production process of plastic products is simplified.
3. Can save a lot of power.
Will the product colored with the masterbatch not fade?
There is no product that does not fade, and products that use color masterbatch may still fade, but the degree of product is different for different grades, some are more obvious, and some are hard to detect.
