Polygon Composites Polylube™ Fiber Series Epoxy Composite Bearings
Categories:	Polymer; Thermoset; Epoxy; Epoxy, Encapsulating, Glass or Mineral Filled
Material Notes:	Low friction coupled with high load carrying capacity are natural benefits. Teflon® superfilaments, which exhibit tensile strength twenty times greater than PTFE resins are integrated into the bearing surface. Polylube bearings resist cold flow and demonstrate impressive wear characteristics. Polygon's patented mechanical process of fiberglass filament weaving/winding results in structures of exceptional strength to support the bearing surface. A filament-wound fiberglass chemically bonded with epoxy, Polylube's structure is naturally concentric with no seam or overlap. Information provided by Polygon Company. Teflon® is a registered trademark of DuPont.
