HPU is a hydrolysis-resistant thermoplastic polyurethane elastomer. HPU's high resistance to hydrolysis (hydrolysis is degradation in water) is rarely found in polyurethanes. It is stable in water up to 90°C and has an outstanding stability in mineral oil.
Because of its resistance to hydrolysis, HPU can be used for water hydraulic and for applications in mining, tunnelling and manufacturing of presses. HPU is particularly recommended for the use in pure and seawater, for HFA and HFB fluids and biologically degradable hydraulic fluids (vegetable oils and synthetic esters) and food articles.
HPU is KTW approved and complies with FDA standards. HPU also has excellent resistance against explosive decompression (ED).
Temperature range from -20 ºC to 110 ºC.
