Polysulphone(PSU)

These unreinforced amorphous thermoplastic materials have a lot of features in common and all three offer a combination of excellent mechanical, thermal and electrical properties.

Main characteristics:
 •  High max. allowable service temperature in air (180 C, 170 C and 150 C continuously for PPSU 1000,PEI 1000 and PSU 1000 repectively)
 •  High mechanical strength, stiffness and creep resistance, also at elevated temperatures
 •  Excellent hydrolysis resistance ( suitable for repeated steam sterilization )
 •  High toughness, also at low temperatures
 •  Physiologically inert (suitable for food contact )
 •  Very good dimensional stability
 •  Translucent, non-optical quality (except for PPSU which is black)
 •  Very good resistance against high energy radiation (gamma and X-rays)
 •  Good electrical insulating and dielectric properties.
