Polysulphone (PSU) is a thermoplastic with high mechanical strength and rigidity. Apart from the high permanent operating temperature, characteristics include remarkably high creep strength over a wide range of temperatures. Due to its amorphous molecular structure, polysulphone is translucent and has a light-brown transparency.  It has a high dimensional stability and very good resistance to hydrolysis rounds off the picture. 
— high operating temperature (160°C)
— very good resistance to hydrolysis (suitable for repetitive steam sterilization)
— high toughness, even at low temperatures
— high dimensional stability
— good electrical insulation
— high mechanical strength
— high rigidity
— high creep resistance over a wide range of temperatures
— good radiation resistance
