H-ECOPUR© Sealing Material

an outstanding material for 

solving special sealing problems.

H-ECOPUR®, a world class polyurethane elastomer developed by ECO-NOMOS® especially for critical sealing purposes, offers a new scope of applications to our customers. Compared to standard polyurethane elastomers, H-ECOPUR® shows outstanding material characteristics such as:

One of the most important benefits H-ECOPUR® is offering to our customers is the superior chemical resistance compared to common polyurethane elastomers. H-ECO-PUR® is not only highly resistant against mineral oils but also against a wide range of polar fluids like

• Water and Sea Water

• Many alcohols like ethanol, etc.

• Silicone oils and greases

• Biologically degradable hydraulic fluids

Therefore H-ECOPUR® is not only used in mineral oil based hydraulic fluids like common polyurethanes but also in water-based fluids like

• HFA and HFB (in mining & steel industry, etc.)

• clear water hydraulics (hydro power stations, etc.)

• fire-resistant pressure fluids based on synthetic esters (HFD-U)

• Environmentally friendly hydraulic fluids based on a natural and syn

• thetic esters (HETG and HEES)
