UTECTHANE - XH [eng.]

General Information

UTECTHANE-XH
is a MDI based polyurethane system which has been specially modified and developed for sealing applications. UTECTHANE-XH has been optimized in regards to hydrolysis stability, mechanical and friction properties. It has high tensile strength, very high abrasion resistance, low hysteresis, very good flexibility at low temperatures (-30/-40 °C) and low compression-set. UTECTHANE-XH has excellent extrusion resistance and allows higher working pressures and larger sealing gaps compared to seals made of PTFE compounds.
