Ppsu. Pei. Psu

Ppsu. Pei. 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
