    The characteristics of PEI injection molded parts include: high temperature stability. Non-reinforced PEI still has good toughness and strength. Therefore, PEI's superior thermal stability can be used to make high-temperature and heat-resistant devices. PEI also has good flame retardancy, resistance to chemical reactions and electrical insulation properties. The glass transition temperature is very high, reaching 215C. PEI also has very low shrinkage and good isodirectional mechanical properties.


    PEI injection molded parts have a wide range of applications, mainly used in electronics, electrical appliances, automobiles, medical, construction and home furnishing and other fields. For example, PEI material has high mechanical strength and stiffness, low flammability and low smoke generation, thus becoming an ideal material for automotive transmission and lighting systems. In addition, PEI can also be used to manufacture aircraft canopies, lighting equipment, industrial safety baffles and bulletproof glass.
