ULTEM® 2300

ULTEM™ 2300: glass‑fiber‑reinforced PEI for structural applications

A reinforced PEI for demanding environments

ULTEM™ 2300 is a SABIC™ polyetherimide grade reinforced with 30% glass fiber. This reinforcement provides increased stiffness, enhanced mechanical strength and excellent dimensional stability while maintaining the inherent thermal resistance of PEI.

Thermal and mechanical performance

The material supports continuous service temperatures around 170 °C and offers good creep resistance for long‑term structural reliability.

Electrical insulation and fire behavior

ULTEM™ 2300 is electrically insulating and inherently flame retardant, meeting UL94 V‑0 and 5VA requirements.
