Ultra-Hard HPU Tube PU Bar Casting PU Hydrolysis-Resistant PU HPU98R
HPU98R is a hydrolysis–resistant (H-PU), casted Polyurethane, based on MDI, Polycarbonate Polyol and certain additives. Due to the excellent overall properties it is recommended as a standard sealing material for most of the hydraulic applications.
Static and dynamic applications, mostly used for U-seals, wipers, step seals and packings up to 400 bar pressure in standard hydraulics. Due to its outstanding hydrolysis resistance it can be used in the most common hydraulic fluids, oil in water emulsions but also water power applications, applications in the mining industry and presses. HPU98R can also be used in applications with contact to foodstuff. We supply HPU tubes with a wide range of diameters with low MOQ required.
