PEI, ULTEM1000, Polyetherimide聚醚酰亞胺, Amber琥珀色
Polyetherimide has a high mechanical strength in coordination with a good chemical and heat resistance (up to +170 °C), good dimensional stability and creep resistance. Its under the thermoplastics singular torque strength permits the economical substitution of machining fabricated small parts from steel.
ULTEM® PEI除了有極佳的高機械性能,還擁有極佳的耐熱及化學穩定性(連續使用溫度大約170度),以及高尺寸穩定性和抗蠕變強度。其在熱塑塑料中獨一無二的抗扭強度,使其成為小型鋼製切銷零件的廉價替代品

★PSU、PPSU和PEI這些非結晶體熱塑形塑料在與極性有機溶劑(如乙醇)接觸時,有非常敏感的應力脆裂性。工作環境對無應力零件完全無害,但對應力大的零件會引起應力脆裂。因此須採用熱處理將應力釋放,將使應力脆裂的危險降到最低。這些非晶體熱塑塑料機械加工時不得使用冷卻液,因為反而會增加環境應力脆裂。此種材料冷卻劑最好採用純水或壓縮空氣
★由於PSU、PPSU和PEI耐磨性差而摩擦係數大,不推薦用在摩擦或耐磨要求的場合
