Polyether Imide (PEI) Filament

Polyether Imide (PEI) is a high-performance, amber-colored thermoplastic renowned for its exceptional strength, thermal stability, and chemical resistance. With a glass transition temperature of 217°C, PEI maintains outstanding dimensional stability even at elevated temperatures, making it a top choice for demanding structural applications.

Key Features:

• High Strength and Thermal Stability: PEI’s remarkable strength and ability to withstand high temperatures make it ideal for creating structural parts that need to maintain their integrity under stress and heat. It is an excellent alternative to traditional materials like steel and aluminum in certain applications, offering similar strength with significantly reduced weight.
• Chemical Resistance: PEI is resistant to a wide range of chemicals, including alcohol, automotive fluids, aqueous solutions, and fully hydrogenated hydrocarbons. This makes it suitable for use in environments where chemical exposure is a concern.
• Inherent Flame Resistance: PEI has built-in flame resistance with low smoke emission, making it an ideal candidate for aerospace, automotive, and electronic applications where safety is paramount.
• Versatile Applications: PEI is used to manufacture a variety of components, including sensors, shafts, levers, connectors, cable ducts, latches, door handles, hard disk drive internals, and fuel cell components. Its high strength, thermal stability, and chemical resistance make it suitable for a wide range of industrial and engineering applications.

PEI filament is an outstanding choice for projects that require materials with superior mechanical properties, heat resistance, and chemical stability. Whether for aerospace, automotive, or electronics, PEI offers unparalleled performance for advanced 3D printing needs.
