Ultem PEI 4000-1100 / 4000-7402 | Glass, PTFE & Graphite Filled PEI ResinUltem PEI 4000-1100 is a glass fiber, PTFE, and graphite filled polyetherimide (PEI) resin engineered for superior wear resistance and low friction. It combines the high thermal and mechanical properties of PEI with excellent sliding performance, making it ideal for bearings, bushings, seals, and other moving parts. Inherently flame retardant (UL94 V0) and dimensionally stable.

Ultem PEI 4001-1100 / 4001-7402 | PTFE Filled PEI ResinUltem PEI 4001-1100 / 4001-7402 | PTFE Filled PEI Resin
Ultem PEI 4001-1100 / 4001-7402 | PTFE Filled PEI ResinUltem PEI 4001-1100 is a PTFE (polytetrafluoroethylene) filled polyetherimide (PEI) resin designed for improved wear resistance and reduced friction. It retains the high thermal stability (Tg 217°C), inherent flame retardancy (UL94 V0 & 5VA), and excellent mechanical properties of base PEI, while adding low friction and good impact strength. Ideal for non‑lubricated bearings, seals, and sliding components.
