MECHETEC PEI
MECHETEC® PEI (Polyetherimide) is an amorphous thermoplastic that is manufactured from SABIC Innovative Plastics’ ULTEM resin. MECHETEC® PEI is extremely rigid, dimensionally stable, and able to withstand continuous operating temperatures of 340˚F. Because it offers superior resistance to autoclave sanitizing and is FDA/USDA compliant, MECHETEC® PEI is routinely specified for reusable machined components used in the medical and pharmaceutical industries. This material also offers electronic and semiconductor designers unmatched dielectric properties that are maintained over a wide frequency range. Unfilled MECHETEC® PEI is dark amber in color and semi-transparent. For applications that require improved stiffness, glass fiber filled grades are available. Formally known as Unitem PEI.
