Ultem – PEI Plastic

Reliable under high temperature conditions

Ultem Machining – Resilience Under Extreme Conditions

ULTEM is a High performance thermoplastic, also known as PEI, or polyetherimide, and is usually transparent amber in colour. Due to its excellent strength and heat resistance, it is popular among Aerospace, Automotive and Medical industries.

At IPFL Ultem would be put through an annealing process to remove any internal stresses, and reduce the risk of surface crazing. We then CNC machine to your specification using our high-speed 3 & 5 axis Milling machines, ideal for cutting reinforced materials.

The Advantages & Uses of Ultem for Machining

Resilience Under Extreme Conditions

Ultem stands out for its ability to withstand high temperatures, chemical exposure, and impact. These properties, combined with its inherent strength and durability, make it a go-to material for applications requiring a flame retardant plastic with superior performance.

Applications of Machined Ultem

Aerospace: Utilized in components requiring heat and impact resistance.
Automotive: Ideal for manufacturing housings, ducts, and semi-structural components.
Electrical Insulation: Employed in parts needing excellent insulating properties.
Medical Industry: Used in medical instrument components
Functional Prototypes and Production Parts: Suitable for advanced prototypes and production parts in demanding applications.
