PSU (Polysulfone)
Tough, rigid transparent thermoplastic with excellent steam sterilization resistance and good thermal stability up to 175°C.

About PSU (Polysulfone)
PSU (Polysulfone) is a tough, rigid, high-strength thermoplastic that maintains its properties over a wide temperature range (-100°C to 175°C). With excellent hydrolytic stability and resistance to steam sterilization, PSU is ideal for medical and food contact applications requiring repeated steam sterilization cycles. PSU is naturally transparent, maintains good dimensional stability, and offers excellent electrical properties, making it suitable for demanding electrical and structural applications.
