Masterbatches (MB)

What are the advantages of masterbatches

Universally applicable

Batches can be used universally within the same polymer family. For example, if a processor has several polymers in use for HFFR components, he can use one and the same batch for certain properties. For certain applications, compounds are “overengineered”. The batch proportion, however, can be flexibly adjusted by the processor. By setting the necessary flame retardant content via batch, he can use only as much flame retardant as is necessary or prescribed by the standard. On the one hand, this saves costs, since flame retardants are more expensive than base polymers. On the other hand, it leads to better mechanical properties, because the more flame retardant is added, the poorer the mechanical properties.

Individual dosage

It is not unusual for a processor to have to produce plastic components in different geometries, such as different wall thicknesses, but at the same time achieve the same fire class for all parts, for example V0. Here he can make use of the fire tests. Based on these tests, he can set the exact batch dosage for each of his parts. This increases his cost efficiency. Certain batches are also used as “boosters.” In this case, an HFFR compound is already present, with which some components just fail the fire test. This can happen with a portfolio of different components with different geometries, especially with thin-walled parts. By adding a few percent booster batch, the components in question then pass the test.

Cost-efficient

Batches are often a more cost-efficient alternative than compounds. It is true that batches are more expensive to purchase than compounds due to the high loading of expensive flame retardants. But since they are blended with cost-efficient standard polymers such as PE or PP during processing, this results in a lower price per kilogram overall than a comparable compound.
