PEI plastic moulding

PEI plastic is polyetherimide, is amber transparent solid, does not add any additives PEI raw material particles have inherent flame retardancy and low smoke, oxygen index of 47%, combustion grade UL94-V -0 grade, the density of 1.28 ~ 1.42g / cm3. PEI has a strong high temperature stability, even non-enhanced PEI, still has a good toughness and strength. So the use of PEI superior thermal stability can be used to make high-temperature heat-resistant devices. With excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance and wear resistance, and through the microwave. PEI also has good flame resistance, chemical resistance and electrical insulation properties. Glass transition temperature is high, up to 215 ℃. PEI also has a very low shrinkage and good mechanical properties in the same direction. Adding glass fiber, carbon fiber or other filler can achieve the purpose of enhancing the modification; can also be composed of other engineering plastics heat polymer alloy, can be -160 ~ 180 ℃ operating temperature long-term use.




Instead of metal-made fiber optic connectors, the component structure can be optimized, simplifying its manufacturing and assembly steps, and maintaining a more precise size. Used in the automotive field, such as sensors used to manufacture high temperature connections, production, high power lights and lights, sensors that control the external temperature of the car compartment, and sensors that control air and fuel mixtures. Can also be used as a high temperature lubrication erosion of the vacuum pump impeller, 180 ° C operation of the distiller's wear glass connector (socket), non-illuminated anti-fog lamp reflector.


PEI main features:


1, PEI Chinese name (polyetherimide) is amber transparent solid, with good flame retardancy and low smoke, combustion grade UL94-V-0 level.


2, PEI has a strong high temperature stability. High temperature, heat distortion temperature of 220 ℃, can be -160 a 180 ℃ operating temperature long-term use.


3, hydrolysis stability is very good, high temperature, resistant to steam


4, polyetherimide has a good anti-ultraviolet, Y-ray performance.

5, PEI resin is a prominent performance is able to withstand long-term high temperature test. This high thermal resistance, coupled with excellent flammability and UL laboratory certification, PEI resin in line with the harsh requirements of high temperature applications.

6, (ductility) PEI resin not only unparalleled both high strength and high modulus characteristics, it also has outstanding ductility. Its yield stretch extends so that it is free to combine a variety of easy-to-fit buckle designs. Even with only 10% glass fiber reinforced, the PEI 2100 resin can maintain ductility in the temperature range below zero to 200 ° C.


7, (impact strength) PEI 1000 resin has excellent practical impact resistance. In view of the PEI resin showing the notch sensitivity, it is recommended to follow the standard design principles. Minimize the application concentration point (eg sharp angle) in the injection molded part to provide maximum impact strength. PEI AT * 100 resin is designed for applications requiring high impact performance. This series of gap Izod impact up to 15km / mз.


8, (fatigue resistance) For the cycle of loading or swing parts, fatigue is a lifetime design considerations.


9, (Creep Behavior) When considering the mechanical properties of any thermoplastic, the designer must recognize the effect of temperature, stress levels and load duration on material properties. The PEI resin also exhibits excellent creep resistance at temperatures and stresses that can not be used with many other thermoplastics.


10, PEI resin has excellent electrical properties, in a wide range of environmental conditions can remain stable. Coupled with thermal and mechanical properties, PEI resins are ideal for demanding electronic and electrical applications.


11, (relative permittivity) Although the application may require a high or low relative permittivity absolute value, but it is more important that these values remain stable over the entire operating temperature and / or frequency range. Plastic Plastic Online Encyclopedia


    PEI resin has inherent characteristics of flame retardancy and low smoke. Some grades of resin at a thickness of 0.25mm grade UL 94V-0 *. Other grades of resin in a large temperature and frequency range are shown high dielectric constant and high dissipation factor.

As an amorphous thermoplastic polyetherimide, PEI resins combine high performance and excellent processing properties to combine high heat resistance with high strength, modulus and extensive chemical resistance.
