This rigid opaque (grey) material offers a unique combination of mechanical properties, resistance to chemicals, wear, fatigue and creep as well as exceptionally high temperature resistance, up to 260°C (480°F). The tensile strength and flexural strength of the PI-coated SCF/PEEK composites showed improvements of 11.8% and 16.6% compared with the commercial cases, which were attributed to the PI sizing treatment effectively improving the interfacial adhesion between the SCF and the PEEK matrix. Indeed, for equivalent mechanical performances, PEKK matrices have lower processing temperatures (around 360°C) simplifying the manufacturing of composite parts. Polyetheretherketone (PEEK) is a high-performance thermoplastic material that is an excellent choice for demanding applications. 30% Glass Filled PEEK has been reinforced with glass fibers, which significantly reduces its expansion rate. It was originally introduced by Victrex PLC, then Imperial Chemical Industries (ICI) in the early 1980s. Glass-Filled PEEK– offers enhanced mechanical and thermal properties over those of basic PEEK, plus excellent resistance in harsh chemical environments and is electrically insulative. Except for the hardness tests, the test specimens were then taken from … Compared to traditional PEEK material, the mechanical and physical properties of PEK remain almost constant at up to 30˚C higher in temperature. The inert chemical nature of PEEK plays a direct role in its mechanical properties and inherent toughness. Chemical Properties PEEK is a semi-crystalline polymer with exceptional chemical resistance to a wide array of reagents, including organic solvents, acids, and bases. Unger says no, they are all roughly the same. February 2004; Journal of Materials Science 39(4) :1499-1501; DOI: 10.1023/B:JMSC.0000013928.77342.37. They also have very low tendency to creep and good sliding and wear properties. When fillers are added to highly stable base polymers such as VICTREX® PEEK, the resulting composites exhibit extremely low CTE values, which makes PEEK a good candidate for applications requiring plastics with CTEs as close as possible to those of metals. [11] Because of this and its low thermal conductivity, it is also used in FFF printing to thermally separate the hot end from the cold end. Conclusions: Compared to PMMA, given the superior mechanical properties of PEEK, it may become the material of choice for future use. It has high resistance to biodegradation. Chen, B., Evans, J.R., 2009. Some grades have a useful operating temperature of up to 250 °C (482 °F). In order to explain the reason why mechanical properties of CNT/PEEK composite cannot linearly increase with the content of CNT, the failure conformation of short-fiber CNT/PEEK composites with 3 wt% CNT was extracted and shown in Fig. ©2021 Curbell Plastics, Inc.

[8] PEEK is considered an advanced biomaterial used in medical implants, e.g., use with a high-resolution magnetic resonance imaging (MRI), for creating a partial replacement skull in neurosurgical applications. PEEK filaments have been demonstrated for producing medical devices up to class IIa. [9] It offers optimal bone growth and is radiolucent, but it is hydrophobic causing it to not fully fuse with bone. PEEK offers wear, moisture and chemical resistance along … PEEK also performs well in applications where continuous high temperatures (up to 500 °F/260 °C) are common. PEEK is partially crystalline, melts at around 350°C, and is highly resistant to thermal degradation. … 3D printing allows the fabrication of thermoplastic composite structures with elevated mechanical properties and complex shapes. plastic with outstanding resistance to harsh chemicals, Chemical resistant, hydrolysis resistant, autoclavable, Good mechanical properties at elevated temperatures.
