UTECTHANE-H is a hydrolysis-resistant cast polyurethane elastomer. lt combines the excellent physicalproperties of UTECTHANE with high resistance to degradation in water (hydrolysis) and can therefore be used in "water hydraulics",such as mining applications,on tunneling machines and at hydraulic presses.UTECTHANE-H is especially recommended for use in seawater, HFA,HFB fire resistant pressure fluids and biodegradable hydraulic fluids (vegetable oil and synthetic esters).
