A PEI resin blended typically with a sulfone resin can yield a material with high heat resistance, high mold flow, and low smoke generation. These are often called PEI copolymers by SABIC Innovative Plastics. SABIC s Siltem PEI-siloxane resin is a block copolymer of PEI and polysiloxane.

In August 2007 GE Plastics became SABIC Innovative, resulting in further developments in HTP technology. It was found, for example, that Extern is miscible with PI, PAI, PEI, PEEK or LCP. - For example, its blends with PEI Ultem show a smooth increase of Tg from about 220 to 311°C following the Fox equation for miscible blends. These transparent or opaque blends may be custom-colored they show an enhanced combination of performances at T< 311°C including inherent flame-retardancy, wear resistance, electrostatic dissipative properties, dimensional stability, etc. TPI blends with PEEK are available as the Victrex -MAX series. ...
