Detailed Performance Characteristics of Special Engineering Plastic PEI (Polyetherimide)

Polyetherimide (PEI) is a high-performance special engineering plastic with the following characteristics:

1. High-Temperature Resistance: With a glass transition temperature as high as 215°C, a heat deflection temperature ranging from 198°C to 208°C, and the ability to withstand long-term use at temperatures between 160°C and 180°C, it can tolerate intermittent use at temperatures up to 200°C.

2. Mechanical properties: It possesses excellent mechanical strength, maintaining high strength and rigidity even at high temperatures. It also exhibits unique toughness and wear resistance, with good impact resistance capable of withstanding moderate external impacts.

3. Electrical insulation properties: It maintains stable dielectric constant and dielectric loss across a wide range of frequencies and temperatures, with high dielectric strength and exceptional electrical insulation properties, making it suitable for electronic and electrical applications.

4. Chemical Resistance and Radiation Resistance: It exhibits excellent resistance to chemicals and radiation, capable of withstanding corrosion from various chemical substances and maintaining stable performance under radiation exposure.

5. Flame Retardancy: It possesses inherent flame retardancy and low smoke emission without the addition of any additives, with an oxygen index of 47% and a combustion rating of UL94-V-0.

6. Processability: It has excellent molding processability and can be processed using various methods such as injection molding, extrusion, and blow molding. However, pre-drying is typically required before processing.

Polyetherimide (PEI) is a high-performance engineering plastic renowned for its excellent high-temperature stability (long-term use temperature exceeding 170°C) and chemical corrosion resistance. It also features high strength, high rigidity, inherent flame retardancy (UL94 V-0 grade), extremely low creep, and excellent dimensional stability. It also exhibits good processing performance in injection molding, extrusion, and other methods, making it widely used in high-demand, high-temperature structural components and insulating parts across industries such as electronics, aerospace, medical, and automotive.
