Influence of storage time and amplitude sweeps on flocculation behavior in silica-filled SSBR compounds

Discover Polymers
The Payne effect reflects the breakdown of filler-filler networks in rubber compounds, particularly in silica-filled systems. However, during storage, time-dependent flocculation of silica clusters leads to an increase in storage modulus, thereby ...

Evaluation of Different Methods for Determining the Entrance Pressure Drop in Capillary Rheometry

Applied Rheology, 2008
Two approaches for determining the entrance pressure drop in capillary rheometry were compared with low-density polyethylene and polystyrene melts as test fluids. Direct measurements with the orifice die were found to yield higher values for the entrance

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...
