About Polyetherimide
What is PEI?
PEI is a semi-transparent, amber-colored polymer that is renowned for its exceptional strength and rigidity. It has a high glass transition temperature (Tg) of 217°C, making it one of the strongest thermoplastics available. This remarkable material also exhibits excellent chemical resistance to acids, bases, and hydrocarbons, as well as high heat resistance and dimensional stability.
Due to its unique properties, PEI is widely used in industries where high-performance materials are required. It is commonly used in medical applications such as surgical instruments and dental tools due to its biocompatibility and sterilizability. In the aerospace industry, PEI is utilized in aircraft components such as brackets, connectors, and insulation due to its lightweight yet strong properties. It is also commonly used in electronic and semiconductor manufacturing, as Polyetherimide can withstand high temperatures and has excellent electrical insulation.
PEI's versatility and durability make it a popular choice for various industrial applications. Its ability to maintain its mechanical strength at elevated temperatures makes it suitable for use in automotive components such as engine parts, gears, and bearings. In the oil and gas industry, PEI is used in downhole tools, pipelines, and valves due to its resistance to corrosion and chemical damage.
In addition to its industrial uses, PEI is also a preferred material for consumer products such as kitchenware, cookware, and food packaging. Its heat resistance and durability make it ideal for use in these everyday products. PEI is also used in the medical field for applications requiring sterilization, such as surgical instruments and dental tools. Its biocompatibility and resistance to chemicals make it a safe and reliable option for these critical items.
PEI's properties make it a versatile material that can be molded into various shapes and sizes using different methods such as injection molding, extrusion, and thermoforming. This allows for customization of products according to specific requirements, making PEI a popular choice among manufacturers.
Superior Strength and Stability
PEI (Polyetherimide) is renowned for its exceptional strength, rigidity, and dimensional stability. It retains its mechanical properties even at elevated temperatures and under harsh environmental conditions, making it a reliable choice for critical applications in industries like aerospace, automotive, and electronics.
High-Temperature Resistance
With a continuous use temperature of up to 340°F (170°C), PEI rods and plates perform well in extreme thermal environments. This high thermal resistance makes it ideal for applications that demand consistent performance under prolonged exposure to heat.
Chemical Resistance
PEI offers outstanding resistance to a wide range of chemicals, including hydrocarbon solvents, alcohols, and various automotive fluids. This chemical durability ensures it can withstand demanding conditions in industrial and mechanical applications where exposure to harsh substances is common.
Outstanding Machinability
PEI materials offer superior machinability, allowing for precision machining to create intricate components with tight tolerances. This makes it a preferred material for engineers and manufacturers looking to achieve high-performance parts with complex designs.
Flame Retardant Properties
PEI is inherently flame-resistant and meets strict safety standards such as UL94 V-0. Its flame-retardant properties make it suitable for use in sensitive applications like electrical enclosures and components, ensuring safety and compliance in critical environments
