Production of Masterbatches

The term masterbatch generally refers to pelletized concentrates of pigments or additives that are embedded in a polymer matrix. They serve to ensure dust-free, accurate, and simple addition of pigments and additives to polymers and compounds.

The concept of the internal mixer is well accepted in the rubber industry, especially for the production of masterbatch compounds. Within a variety of materials the deformation of rubber compounds is relatively difficult due to the very high viscosity. Mixing devices have to be strongly powered and have to be designed in a very robust way in order to withstand the very high forces and momentum acting on the device. The most important benefits of an internal mixer are...
