This quantity indicates how much energy a rubber component (such as a tire tread or shoe sole) absorbs and how much it returns after an impact (elasticity).<\/p>\n<p>The model manufactured by <strong>Polymer Test<\/strong> replaces outdated analog pointer systems with advanced digital sensors, eliminating visual reading errors and providing results with 0.1% precision.<\/p>\n<h3>Operating Mechanism and Smart Features<\/h3>\n<p>The device operates based on the potential and kinetic energy of a pendulum. Key features of this digital model include:<\/p>\n<ul>\n<li><strong>Automatic Release System:<\/strong> Unlike manual models where the operator&#8217;s hand tremor can affect the pendulum release, in this device, the hammer is released via an electromagnet and software command, ensuring 100% repeatability.<\/li>\n<li><strong>Measurement Precision:<\/strong> Exact calculation of the rebound angle and its conversion to <strong>Rebound %<\/strong> using an internal high-resolution encoder and processor.<\/li>\n<li><strong>Standard Hammer Design:<\/strong> Utilizes a spherical hammer with an impact energy of <strong>0.5 Joules<\/strong> and a calibrated center of percussion.<\/li>\n<\/ul>\n<h3>Standard Sample Preparation<\/h3>\n<p>To perform this test, you require button-shaped samples with a specific thickness.
