How to distinguish the quality of masterbatch



Dedicated masterbatch: It is a masterbatch made of the same type of plastic specified by the user for the finished product, using the same plastic as the carrier. For example, PP masterbatch and ABS masterbatch are respectively selected from PP and ABS.

General-purpose masterbatch: A resin (each of which is a low-melting PE) is also used as a carrier, but it can be used for coloring other resins than its carrier resin.

Most of the internationally regular masterbatch companies do not usually produce universal masterbatches.

There are many disadvantages to the universal masterbatch. In fact, the general-purpose masterbatch has a narrow 'general' category, and its skill indicators and economic benefits are also poor.

1. Poor predictability of coloring results

The masterbatch is used for coloring, and the pigment of the universal masterbatch will have a different color in the difference plastic guess, so the coloring result is less predictable.

2. Affect other properties of plastic finished products

In particular, the strength is affected, and the product is easily deformed and twisted, which is more remarkable for engineering plastics.

3. The cost is higher

In order to be roughly 'universal', the universal masterbatch often uses a higher heat-resistant grade of pigment, resulting in waste.

In addition to coloring, can the masterbatch have the effects of flame retardant, brightening, antistatic, anti-oxidation and anti-ultraviolet rays?

Masterbatch can have some of these effects at the same time, if the workshop asks for this.

Occasionally, although the customer did not ask for it, the masterbatch company will also initiate the user to add some additives depending on the necessity of the product, such as the growth of certain additives such as brighteners in the masterbatch. Of course, this will increase the cost of the product.
