What is the difference between silicone powder and silicone masterbatch?

The difference between silicone powder and silicone masterbatch is that silicone powder is powdery, while silicone masterbatch is granular.
If the raw material you are using is powdery, using silicone powder can better blend, but if your raw material is granular, it is recommended that you still use silicone masterbatch, which is easier to shear and disperse.
