1): PEI is a thermoplastic engineering resin with excellent stability2): One outstanding performance of PEI resin is the ability to withstand long-term high temperature tests. This high heat resistance, combined with excellent flammability and UL laboratory certification, makes PEI resins meet the demanding requirements of high temperature applications.3): (Extensibility) PEI resin not only has unparalleled high strength and high modulus, but also has outstanding ductility. Its yield stretch extends its freedom to incorporate a variety of snap fit designs that are easy to assemble. PEI 2100 resin maintains ductility from sub-zero to 200 ° C even with only 10% glass fiber reinforcement.4): (Impact strength) PEI 1000 resin has excellent practical impact resistance. Since PEI resins show notch sensitivity, it is recommended to follow standard design guidelines. The application of concentrated points (such as sharp corners) in injection molded parts should be minimized to provide maximum impact strength. PEI AT*100 resin is designed for applications requiring high impact performance. This series of notched Izod impacts can reach 15km/mз.
Due to its excellent balance performance, PEI is used effectively in industrial sectors such as electronics, motors and aerospace, and as a substitute for metal for traditional products and cultural goods. Fabrication of fiber optic connectors with PEI instead of metal optimizes component construction, simplifies manufacturing and assembly steps, and maintains more accurate dimensions. Used in automotive applications such as high temperature connectors, high power lights and indicator lights, sensors that control the temperature outside the cabin (air conditioning temperature sensor) and sensors that control the temperature of the air and fuel mixture (effective combustion temperature sensor). It can also be used as a vacuum pump impeller for high temperature lubricating oil erosion, a ground glass joint of a steamer operated at 180 °C, a mirror for non-illuminated anti-fog lamps.
1): (Fatigue resistance) Fatigue is a lifelong design consideration for cyclic loading or swinging components.
2): (creep behavior) When considering the mechanical properties of any thermoplastic, designers must be aware of the effects of temperature, stress levels and load duration on material properties. Even at temperatures and stress levels where many other thermoplastics cannot be used, PEI resins show excellent creep resistance.
3): PEI resin has excellent electrical properties and can be stable under a wide range of environmental conditions. Together with thermal and mechanical properties, PEI resins are ideal for demanding electronic and electrical applications.
4) (relative dielectric constant) Although the application may require an absolute value of the relative dielectric constant of high or low, it is more important that these values remain stable over the entire operating temperature and/or frequency range.
PEI resin is a high performance amorphous engineering thermoplastic.
PEI resin has inherent flame retardancy and low smoke generation. Some grades of resin have a rating of UL 94V-0* at a thickness of 0.25 mm. Other grades of resin exhibit high dielectric constant and high dissipation factor over a wide range of temperatures and frequencies.
As an amorphous thermoplastic polyetherimide, PEI resin combines high performance with excellent processing characteristics to combine high heat resistance with high strength, modulus and extensive chemical resistance.
