Ultem (PEI) Round Bars

Strong, flame-resistant plastic rods for precision-machined parts :

ULTEM round bars, also known as PEI rods or Polyetherimide rods, are solid engineering plastic rods used mainly for machining precision components. Unlike sheets, ULTEM rods are selected when parts need cylindrical geometry, tight tolerances, and reliable strength at elevated temperatures.

These ULTEM plastic rods offer high stiffness, excellent dimensional stability, and inherent flame resistance. They absorb very little moisture and maintain their shape during machining and long-term service, making them suitable for electrical, aerospace, medical, and industrial equipment applications.

What Makes Our Ultem Rods Different :

ULTEM rod performance depends on material consistency and diameter control. Our rods are produced to support accurate machining and repeatable part quality.

Features Our Advantage
High Temperature Resistance : Reliable up to 170°C in continuous use.
Inherent Flame Retardancy : Flame resistant without additives.
High Mechanical Strength : Rigid and load-bearing.
Dimensional Stability : Maintains size during machining and service.
Low Moisture Absorption : Prevents swelling or distortion.

Key Advantages :

  • Ideal for precision-machined components.

  • High strength and stiffness.

  • Stable performance at elevated temperatures.

  • Excellent electrical insulation.

  • Low smoke generation.

  • Long service life.

Applications & Industries :

  • Electrical & Electronics : Insulating rods, connectors, structural parts.

  • Aerospace & Railways : Lightweight, flame-resistant components.

  • Medical Equipment : Machined parts requiring strength and stability.

  • Industrial Machinery : Spacers, rollers, structural supports.

  • Automotive : Electrical and under-hood components.
