Features: • High Flexibility:Will not bend or break with impact damage reduction on road surfaces and trucks, even at -35° • Extended Work-Life:Better wearing properties than UHMW. Outlasts rubber by up to 10 times and steel by up to 5 times. Lower maintenance costs, increased productivity and profits • Non-Damaging to Surfaces: Cutting edge will not damage Brick/Cobblestone, Stamped Concrete or Asphalt, Paver Stones, Parking Lots, Curbs, Speed Bumps, or Manhole Covers like steel bars • Less Equipment Wear:Due to the higher vibration absorption property of polyurethane • Benefits of Polyurethane Over Rubber Cutting Edges:Polyurethane memory bounces back to its original shape after impact. Rubber holds its flexed shape, severely reducing efficiency and work life
