introduction
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.

FAQ
Machining PEI Ultem 1000 Buying FAQ
No, PEI (Polyetherimide) and Ultem are not exactly the same, but Ultem is a brand name for a type of PEI. Ultem is a high-performance thermoplastic material that falls under the broader category of PEI plastics. While people often use the terms interchangeably, it's essential to note that Ultem is a specific brand of PEI, and there are other variations of PEI with different properties.
PEI Ultem 1000 tends to be more costly than other plastics. Additionally, processing PEI Ultem 1000 can be challenging, demanding specialized equipment and expertise. Furthermore, there are limited color options as it is generally found in amber or natural colors, restricting aesthetic choices for users.
PEI Ultem 1000 is highly durable and exhibits excellent mechanical strength. It is known for its long-term stability and reliability.
Painting PEI Ultem 1000 can be challenging due to its inherent chemical resistance, which may make it difficult for paints to adhere. Surface treatments and primers designed for high-performance plastics may be required for successful painting.
Yes, PEI Ultem 1000 can be 3D printed. It is a popular material for additive manufacturing due to its high-temperature resistance and mechanical properties. However, 3D printing with PEI Ultem 1000 may require specialized equipment to handle high temperatures.
