Polikim ULPOLEN® 500 UHMWPE Standard
Categories: Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); UHMW PE (Ultra High Molecular Weight PE)

Material Notes: Standard Ulpolen® 1000 is the universal type primarily preferred on the condition that its technical properties meet operating environment requirements. It is more cost efficient compared to special types with additives. One major problem in the identification and selection of materials is the difficulty in distinguishing Ulpolen® 1000 from other lower quality polyethylene types in terms of physical apperance. The main differences in technical properties are evidenced in laboratory tests. Variations of Ulpolen® 1000 within its group according to molecular weights and its physical similarity to other polyethylene types are vital factors that should be carefully studied to select the right material for the application. In addition to “1000” quality, there are subgroups with different technical properties such as Ulpolen® 500 which is primarily used in food industry as cutting plates (with 0.5 million molecular weight) and Ulpolen® 300 which is used in chemical industry in the production of tanks resistant to chemicals (with 0.3 million molecular weight).
