Special masterbatch: It is a masterbatch manufactured by using the same plastic as the carrier according to the plastic variety specified by the user for the finished product. For example, PP masterbatch and ABS masterbatch use PP and ABS as carriers respectively.
General masterbatch: It also uses a certain resin (often low-melting-point PE) as a carrier, but it can be used for coloring other resins than its carrier resin.
The vast majority of international masterbatch companies generally do not produce universal masterbatch.
General masterbatch has many disadvantages. In fact, the "universal" category of universal masterbatches is very narrow, and the technical indicators and economic benefits are also poor. The detailed table is now:
- Poor predictability of coloring results
The masterbatch is used for coloring. The pigment of the general masterbatch will show different colors in different plastic guesses, so the predictability of the coloring result is poor.
- Other properties that affect the finished plastic products
Especially affect the strength, the product is easy to deform and twist, which is more significant for engineering plastics.
- Higher cost
In order to be roughly 'universal', the general-purpose masterbatch often uses pigments of higher heat-resistant grade, which causes waste.
In addition to coloring, can the masterbatch also have flame retardant, brightening, antistatic, anti-oxidation, anti-ultraviolet and other effects?
Masterbatch can have some of these effects at the same time if the factory puts forward this requirement.
Occasionally, although the customer did not make a request, the masterbatch company will also initiate the user to add some additives as necessary for the product, like adding some additives to the masterbatch, such as brightener. Of course, this will increase the cost of the product.
