Poly-Texx MPG is the most abrasive resistant filled polymer material available. Its natural color is orange or blue. Typical applications include sleeve and flanged bearings and thrust washers for high aggregate bearing applications. Its excellent chemical resistance makes it suitable for chemical and solvent rich environments. Its main attribute is its resistance to abrasion from particulate such as sand, wood pulp and paper dust. Available in many shapes and sizes, it is easily machined to close tolerances (with experience) and can be sawed, milled and turned with most metal working equipment. Poly-Texx MPG is a great choice for many demanding applications. See our Technical Assistance page on our website for details.
