Joint Institute for Nuclear Research, Dubna, Russia Main characteristics of polyethylene there phthalate track membranes (TM) made of 10 and 20 mkm films were studied. Membranes with pore diameters of 0.2, 0.4 and 1mkm were tested. Using various techniques, the following structural parameters of TM were defined: pore density and average size, bubble point, pore size distribution. For all membrane types their tensile strength and also the specific water and gas flow rates were measured. The liquid medium filtration performance of the membranes was investigated. The advantages of thick film based membranes are discussed.
