1）：PEI是一种稳定性能的热塑性工程树脂
2）：PEI树脂的一个突出性能是能够经受长时间的高温考验。此耐高热性能，加上出色的可燃性和UL实验室的认证，使PEI树脂符合了高温应用的苛刻要求。
3）：（延展性）PEI树脂不但无伦比地兼有高强度与高模量的特性，它还具备突出的延展性。其屈服拉伸延伸得它能够自由结合各种便于装配的搭扣配合设计。甚至在只加入了10%玻纤增强的情况下，PEI2100树脂也可在零度以下至200℃温度范围内保持延展性。
4）：（冲击强度）PEI1000树脂具有出色的实际抗冲击性能。鉴于PEI树脂显示缺口灵敏度，建议遵守标准设计原则。应大限度地减少注塑部件中的应用力集中点（如尖角），以提供大有冲击强度。PEIAT*100树脂专用于需要高冲击性能的应用。此系列的缺口Izod冲击可达15km/mз。
5）：（耐疲劳性）对于循环装填或摆动部件，疲劳是一生要的设计考虑因素。
6）：（蠕变行为）在考虑任何热塑性塑料的机械性能时，设计师必须认识到温度，应力水平和负荷持续时间对材料性能的影响。机使在无法使用许多其他热塑性塑料的温度和应力水平下，PEI树脂也显示了极好的抗蠕变性能。
1) : PEI is a thermoplastic engineering resin with stableperformance
2) : One of the outstanding properties of PEI resin is that itcan withstand long-term high temperature test. This high heatresistance, combined with excellent flammability and UL laboratorycertification, makes PEI resin meet the stringent re ofhigh temperature applications.
3) : (Ductility) PEI resin not only has the characteristics ofhigh strength and high modulus, but also has outstanding ductility.Its yield stretch extends so that it can freely combine variousbuckle fit designs for easy assembly. Even when only 10% glassfiber is added, PEI2100 resin can maintain ductility in thetemperature range from below zero to 200 ℃.
4) : (impact strength) PEI1000 resin has excellent actual impactresistance. Since PEI resin shows notch sensitivity, it isrecommended to follow the standard design principles. Theapplication force concentration points (such as sharp corners) ininjection molded parts should be minimized to provide great impactstrength. PEIAT * 100 resin is designed for applications re impact performance. The notch Izod impact of this series canreach 15km/m з。
5) : (fatigue resistance) For cyclic loading or swing parts,fatigue is a life-long design consideration.
6) : (Creep behavior) When considering the mechanical propertiesof any thermoplastic, the designer must recognize the influence oftemperature, stress level and load duration on the materialproperties. PEI resin also shows excellent creep resistance attemperatures and stress levels where many other thermoplasticscannot be used.
