PEI Ultem 1000 in CNC Machining and Injection Molding

PEI Ultem 1000 is a high-performance thermoplastic material with excellent strength, high heat resistance, and chemical resistance. It belongs to the family of polyetherimide (PEI) polymers.

It can withstand continuous use at high temperatures. It is durable and reliable, with high tensile strength, stiffness, and impact resistance. It also has excellent chemical resistance, which can be used in applications exposed to harsh chemicals. PEI Ultem 1000 can be machined at speeds similar to those used for metals. We use carbide or PCD (polycrystalline diamond) tools for efficient machining. It can be post-processed by polishing, sanding, or bead blasting to achieve the desired surface finish.

PEI Ultem 1000 is heat resistant, an electrical insulator, and a flame retardant. Additionally, it’s biocompatible and maintains its shape and dimensions even when exposed to temperature variations. Using advanced extrusion technology, it’s available in various shapes and sizes. It is a budget-friendly choice, outperforming PES, PEEK, and Kapton in machining high-heat applications. It can be easily processed through thermoforming, extrusion blow molding, and injection molding with excellent results.
