PEI/Ultem Key Properties

  • Thermal Performance:
    PEI's outstanding thermal stability sets it apart. It can withstand continuous use at elevated temperatures, typically up to 170°C (340°F), making it ideal for applications demanding heat resistance. Whether in automotive components or aerospace interiors, count on PEI to maintain its integrity even in extreme thermal environments.

    Exceptional Mechanical Strength:
    PEI boasts impressive mechanical properties. Its high tensile strength and rigidity make it an excellent choice for structural components where strength and stability are paramount. This material resists deformation under heavy loads, ensuring longevity in demanding applications such as medical devices and electronics.

  • Chemical Resistance and Electrical Insulation:
    PEI offers remarkable chemical resistance, standing up to a wide range of chemicals, acids, and solvents. Additionally, it excels as an electrical insulator, making it valuable in electrical and electronic components. Its dielectric properties make it a preferred material for insulating parts in the semiconductor and electrical industries.

    Dimensional Stability and Precision:
    PEI's exceptional dimensional stability ensures that components retain their shape and size, even in fluctuating environments. This property is crucial for maintaining tight tolerances in precision engineering applications, including aerospace manufacturing and automotive engineering.

  • Biocompatible and FDA Compliant:
    PEI is biocompatible and FDA compliant, making it suitable for medical and healthcare applications. From surgical instruments to sterilizable components, PEI's biocompatibility and resistance to autoclave sterilization ensure safety and reliability.

    Versatile and Easy to Process:
    PEI's versatility extends to ease of processing. It can be injection molded, machined, and 3D printed, offering flexibility in design and manufacturing. This adaptability simplifies the production of custom components across a wide range of industries.
