Universal masterbatch has many shortcomings. In fact, the universal range of universal masterbatch is very narrow, and the technical indicators and economic benefits are also poor.
Special color masterbatch: It is a color masterbatch manufactured by selecting the same plastic as the carrier according to the plastic variety specified by the user for the product. For example, PP masterbatch and ABS masterbatch respectively use PP and ABS as carriers.
Universal color masterbatch: It also uses a certain resin (often a low melting point PE) as a carrier, but it can be applied to the coloring of other resins other than its carrier resin.
Universal masterbatch is relatively simple and convenient, but there are many disadvantages. It is recommended that you choose a special masterbatch.
Why don't many companies produce universal masterbatch?
Most of the international masterbatch companies generally do not produce universal masterbatch.
Universal masterbatch has many shortcomings. In fact, the range of ‘universal’ for universal masterbatches is very narrow, and the technical indicators and economic benefits are also poor. The specific manifestations are:
1. Poor predictability of coloring effect
Masterbatch is used for coloring. The pigments of general masterbatch will show different colors in different plastics, so the predictability of the coloring effect is poor.
2. Affect other properties of plastic products
Especially affects the strength, the product is easy to deform and twist, which is more obvious for engineering plastics.
3. Higher cost
Universal color masterbatch in order to be 'universal', often use higher heat-resistant pigments, causing waste.
In addition to coloring, can the masterbatch also have the functions of flame retardant, brightening, antistatic, anti-oxidation, and ultraviolet resistance?
Masterbatch can have some of these functions at the same time, if the factory requests this.
Sometimes, although the customer does not make a request, the masterbatch company will also suggest the user to add some additives according to the needs of the product, such as adding certain additives to the masterbatch, such as brightener. Of course, this will increase the cost of the product.
