How to choose the carrier of white masterbatch？

In the application of white masterbatch, there are many kinds of carriers that can be used to fill the masterbatch. The commonly used carriers are mainly APP, LDPE, LLDPE, HDPE, PP, HIPS, CPE, EVA, PVC and waste materials of these plastics, such as waste PE. , PP, etc.

The carrier may be used singly or in combination of two or more kinds, such as LDPE/LLDPE and LLDPE/HDPE. The composite carrier is the same as EVA and CPE, and has good compatibility with most of the resins, so that the masterbatch has wide adaptability. The single carrier should theoretically be identical to the matrix resin being filled, so that the compatibility is good. However, it is practically impossible to make too many kinds of master batches, and thus the carrier resin is similar to the resin to be filled.

The amount of the white masterbatch carrier is generally about 15% to 30% of the master batch, and sometimes only about 5% is used to reduce the cost of the white masterbatch.
