ULTEM (Polyetherimide / PEI) is a high-performance amorphous thermoplastic offering exceptional mechanical strength, dimensional stability, and inherent flame resistance across a wide temperature range. It operates continuously to 340°F (170°C) without significant loss of properties. Steam sterilisation resistant and inherently flame retardant, Ultem is a trusted material for aerospace, medical, and food-grade applications.
Dynex USA supplies Ultem (PEI / Polyetherimide) rod and sheet in natural and black grades. Available to order for distributors and stockists — contact our team for lead times and pricing. Fast shipping from our Pennsylvania warehouse.

Choose ULTEM when your application demands high thermal resistance, dimensional stability, and excellent electrical insulation, particularly for components exposed to steam sterilisation, high heat, or requiring stringent flame, smoke, and toxicity compliance.
ULTEM NAT is the standard ULTEM (PEI) grade. FDA compliant with broad chemical resistance and semi-transparent amber appearance. The go-to grade for aerospace, medical, and food processing applications requiring high-temperature performance and regulatory compliance.
ULTEM BLK is a black ULTEM (PEI) grade with identical mechanical and thermal performance to ULTEM NAT. Black pigmentation adds UV resistance for outdoor and high-visibility industrial applications.
