Overview :

Polyetherimide (PEI) is an amorphous, amber transparent, non-crystalline high-performance engineering thermoplastic with exceptional qualities. It offers high strength and rigidity at elevated temperatures, long-term heat resistance, dimensional stability, and good electrical properties. As an amorphous, high-temperature resin, PEI is inherently flame retardant and exhibits resistance to various chemicals. Its creep resistance allows for replacing metals in structural applications, and electrical properties remain stable under variable conditions. PEI's versatility makes it valuable in industries such as aerospace, automotive, and electronics.

FAQ:

What is PEI material?

Polyetherimide (PEI) is an amorphous thermoplastic known for its high mechanical strength and rigidity. It is commonly recognized by the trade name ULTEMTM plastic or ULTEMTM material.

Q1

What is polyetherimide used for?

Polyetherimide (PEI) is a versatile thermoplastic used in aerospace, automotive, and electronics for its high strength, heat resistance, and electrical properties. It finds applications in medical devices, membrane technology, and industrial components, offering biocompatibility and flame retardancy.

Q2

Whether to provide the sample and the delivery time of the sample ?

We can provide a sample of 3kg in stock within 5 working days.

Q3

Can you provide customized services?

Yes, all our raw materials can be customized, such as adding glass fiber, carbon fiber and other fillers, or making boards and rods of different sizes. Click for details to learn more>>

Q4

Can polyetherimide be 3D printed?

Polyetherimide can be 3D printed. PEI is known for its excellent thermal and mechanical properties, making it a suitable material for 3D printing, especially in applications that require high-performance characteristics. The most common method of 3D printing with PEI is using a technology called Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF). In this process, PEI filament is melted and extruded layer by layer to create the desired 3D-printed object.

Q5

Can you provide the quality certificate of the products?

Of course. All of our products are proven to be perfectly compliant with FDA, REACH and RoHS safety regulatory, and so on. If you need, you can contact us to check the relevant documents.

Q6

Is polyetherimide expensive?

The cost of Polyetherimide (PEI) varies depending on factors such as grade, form (sheets, rods, filaments), and supplier. Generally considered a high-performance engineering thermoplastic, PEI tends to be more expensive than common plastics. The unique combination of properties, including high mechanical strength and thermal resistance, contributes to its higher cost. Specific pricing details would depend on the source and market conditions at the time of purchase. It's advisable to consult suppliers or manufacturers for current and specific pricing information.

Q7

Are you manufacturer or trading company?

We are integral part of industry and trade. Both the agency of some products, but also a factory for product development and production.

Q8

About bulk order leading time?

It will take about 15~30 working days from order confirmation to production completion. Specific communication can be coordinated to the time acceptable to both side.
