Individual Plastic Granules
hardness, fracture, brittleness, stiffness
We tested the hardness, resilience & springiness of plastic granules that had good and poor flow characteristics with the TA.XTPlus Texture Analyzer and a TA-52 2 mm diameter stainless-steel punch probe. The small flat probe allowed the probe face and the base plate to be as parallel as possible. The probe’s small size allowed multiple granules to be tested without recalibrating the probe height each time. For this study we tested the granules directly against the TA-90 Heavy-Duty platform’s base plate.
