Leading market players in the silicone industry have used the Buss Kneader very successfully for decades, on the one hand as a high-capacity continuous reactor in polymer production by polycondensation or polymerization. Important reasons for this include the Buss Kneader’s excellent handling of very wide viscosity spectra, precise feed of reactants through hollow-drilled kneading pins, perfect temperature control, and trouble-free operation at very low absolute pressure.
Another application area is the compounding of silicone elastomers (HTV) and silicone sealants (RTV). Reinforcing materials such as highly dispersed silicic acid or classic fillers and other formulation components are fed in during compounding, and undesirable accompanying materials are removed. In combination with extremely high fold numbers, the moderate shear rates enable excellent mixing results and very high viscosity compounding without local overheating.
Thanks to the modular and thus adaptable design of entire systems, and the broad-based Buss process expertise, the Buss Kneader is an excellent choice for silicone polymer production and silicone compounding in all classes.
