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,
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.
