PEI is a remarkable thermoplastic that boasts a unique set of properties and a wide range of applications. Join us as we explore the versatility and versatility of this extraordinary material.
Understanding Polyetherimide (PEI)
Polyetherimide, often referred to by its trade name ULTEM™, is a high-performance thermoplastic known for its outstanding thermal, mechanical, and electrical properties. Developed by SABIC Innovative Plastics, PEI has become a go-to material in various industries, thanks to its impressive combination of characteristics.
Key Properties of PEI
Exceptional Heat Resistance
PEI can withstand continuous exposure to high temperatures, making it an excellent choice for applications requiring thermal stability. It maintains its mechanical strength and dimensional stability at temperatures exceeding 300°C (572°F), making it suitable for use in extreme environments.
Outstanding Chemical Resistance
PEI exhibits excellent resistance to a wide range of chemicals, including acids, bases, and hydrocarbons. This property makes it ideal for applications where exposure to aggressive chemicals is a concern.
High Strength and Stiffness
PEI offers impressive mechanical properties, including high tensile strength and stiffness. It maintains its structural integrity under heavy loads and performs well in applications demanding rigidity and durability.
Dimensional Stability
PEI has low moisture absorption and minimal thermal expansion, ensuring excellent dimensional stability over a wide temperature range.
Flame Resistance
PEI is inherently flame-resistant and can meet various industry-specific fire safety standards without the need for additional flame retardant additives.
Applications of PEI
Aerospace and Aviation
PEI's heat resistance and flame retardancy make it a preferred choice for aircraft interior components, such as cabin panels, seat frames, and electrical connectors.
Medical Devices
The biocompatibility and sterilizability of PEI make it suitable for medical device applications, including surgical instruments, equipment housings, and dental tools.
Electronics
PEI's electrical insulating properties make it an ideal material for electrical connectors, sockets, and components in high-performance electronic devices.
Automotive
PEI's combination of high strength, heat resistance, and chemical resistance is valuable in automotive applications, including sensors, connectors, and under-the-hood components.
Food Processing
PEI's food-contact compliance, chemical resistance, and ability to withstand high temperatures make it suitable for food processing equipment such as trays, housings, and conveyor components.
