Research. Publications. Patents. Alumni: Novel Materials Made by SolidState Shear Pulverization. Solidstate shear pulverization (SSSP) is a novel mechanical process that uses a modified twinscrew extruder with cooling zones to maintain the polymer in the solid state during processing.

Vulcanized natural rubber was pulverized using a single screw extruder in a noncryogenic Solid State Shear Extrusion (SSSE) process where rubber granulates were subjected to high compressive and shear stresses. The produced particles had diameters ranging from 40 to 1700 µm.

Rubber granules were pulverized using the single screw Solid State Shear Extrusion (SSSE) process. This process is noncryogenic and pulverization takes place under high shear and compression conditions. The effects of operating variables such as temperature and shear rate were examined, and optimum conditions were identified.
