350°C, whereas PEEK often requires extruder temps of 400°C or higher.  ThermaX™ PEKK has a lower rate and degree of crystallinity than PEEK, which aids in its ease of printing.  However, once printed and annealed, PEKK parts exhibit superior performance vs. PEEK.  Easier to print + superior performance!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermaX™ PEKK product attributes include:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePEKK-C is made using the 70\/30 PEKK copolymer\u003c\/li\u003e\n\u003cli\u003eSubstantially easier to print than PEEK\u003c\/li\u003e\n\u003cli\u003eContinuous Use Temperature (CUT) of 260°C, and higher for short duration\u003c\/li\u003e\n\u003cli\u003eGlass Transition Temp (Tg) of 162°C (20°C higher than PEEK)\u003c\/li\u003e\n\u003cli\u003eMelt Temp (Tm) of 335°C  (allows for lower print temps than PEEK)\u003c\/li\u003e\n\u003cli\u003eInherent flame resistance (UL94 V-0)\u003c\/li\u003e\n\u003cli\u003eLow smoke generation for aerospace applications\u003c\/li\u003e\n\u003cli\u003eOutstanding mechanical, thermal, and chemical resistance\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to a broad range of chemicals, such as those used in the oil\/gas, automotive, aerospace, industrial, and chemical processing industries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFilament Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDiameter:  1.75mm, 2.85mm (+\/- 0.05mm)\u003c\/li\u003e\n\u003cli\u003eColors:  Natural\u003c\/li\u003e\n\u003cli\u003eLarger reel quantities available upon request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Print Conditions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExtruder Temp:  345 -
