UNITEM® PEI - SOLIAO

About
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. PRODUCT ATTRIBUTES 340°F continuous use temperature Semi-transparent with light amber color Excellent strength and rigidity, even at elevated temperatures Low moisture absorption Superior electrical properties Rated UL V-0 Easily machined and fabricated FDA, USDA compliant Glass fiber filled grades for improved strength and stiffness INDUSTRIES Medical and pharmaceutical Aircraft and aerospace Fluid handling Electrical and electronics manufacturing Microwave communications APPLICATIONS Sight glasses Manifolds Electrical insulators Electrical component housings Aircraft instrumentation&&
