ECOPUR is a thermoplastic polyurethane elastomer (TPU), which has an unusually high abrasive resistance, low compression set, high physical properties and tear strength. In sealing technology ECOPUR is mostly used for U-cups, lip seals, wipers and packings, but it may also be used for dampers and other machined parts. Products made from this material can be used in mineral oil, in water up to 40°C and in bio-degradable hydraulic oils like vegetable oils and synthetic esters up to 60°C. Depending on the seal design and the housing conditions seals made of ECOPUR can be used up to 400 bar (for high pressure demands, experts from SKF recommend to use anti-extrusion-rings).
