Polyetherimide (Med) Specifications

Description

Medical grade Polyetherimide (Med) is made from polyetherimide resin, an amorphous thermoplastic which exhibits excellent resistance to a wide range of chemicals and disinfectants. Polyetherimide (Med) maintains its size and shape over a broad temperature range as well as tolerates a high amount of stress over extended periods of time. Recommended sterilization techniques for Polyetherimide (Med) include EtO gas, radiation, steam autoclaving, dry heat and cold sterilization.

Applications

Provisional trials • Instrument handles • Medical device components
