Ecopur is a thermoplastic polyurethane elastomer, 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-rings, lip seals, wipers and chevron 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 biodegradable hydraulic oils like vegetable oils and synthetic esters up to 60°C (in these hydraulic fluids its better to use H-Ecopur instead of Ecopur).
Depending on the seal design and the installation housing, seals made of Ecopur can be used up to 400 bar (for higher pressure, anti-extrusion rings are necessary).
