density of plastics – gradient column method

gradient column method

One of the most accurate methods to determine the density of plastics and rubbers in kg/m3 is the gradient column method (ISO 1183-2). The principle of the method is that two miscible liquids can be mixed at a control mixing rate and temperature into a tube so that a uniform density gradient is formed from the top to the bottom of the tube. Calibrated floats with known density are then immersed in to the tube for reference.

At impact we are accredited by UKAS for this test and we are equipped with a state-of-the-art three column automatic density gradient from Ray-Ran, UK.
