Technical Data
产品说明
UNITEM Polyetherimide (PEI) is an amorphous thermoplastic that is manufactured from SABIC Innovative Plastics' ULTEM resin. UNITEM 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, UNITEM 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 UNITEM PEI is dark amber in color and semi-transparent. For applications that require improved stiffness, glass fiber filled grades with filler levels of 10%-40% are available. Nytef Plastics' UNITEM PEI stock shapes are UL V-0 rated and available in a full range of heavy gauge rod, plate and tubular bar sizes.
