Whats the carrier of black masterbatch?
08/02/2018
The carrier is a substance that carries carbon black. What kind of raw materials are used for general plastic products, and what raw materials are used for the carrier. The black masterbatch thus produced has good compatibility with the plastic raw material. For example, PS (polystyrene) plastic products, the black masterbatch carrier used is PS. For polyethylene plastic products, the carrier is polyethylene.

However, LDPE (high pressure polyethylene) is generally used because LDPE has the strongest ability to carry carbon black and has good processing performance. Other polyethylene HDPE and LLDPE can only produce low concentration black masterbatch. For PP (polypropylene) plastic products, only black masterbatch with PP and LDPE as the carrier can be used, but black masterbatch with HDPE and LLDPE and other plastics as the carrier cannot be used. Of course, the black masterbatch which uses the recycled material as a carrier is also used.
