With excellent mechanical properties, resistance to thermal degradation and excellent strength. Soft Matter 5 (19), 3572–3584. PEEK is a thermoplastic with extraordinary mechanical properties. The light thermoplastic can support multiple requirements at the same time – to solve material limitations in applications, often replacing metals, and to meet cost-efficiency and sustainability needs. The high thermal stability is provided by the diphenylene ketone groups which impart high strength and high resistance to oxidation, but make the polymer rigid. Some grades have a useful operating temperature of up to 250 °C (482 °F). Polyetheretherketone (PEEK) is a semi-crystalline, high-performance engineering thermoplastic.

Wear Resistance High abrasion and cut through resistance combined with a low coefficient of friction. [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. Typical is the reaction of 4,4'-difluorobenzophenone with the disodium salt of hydroquinone, which is generated in situ by deprotonation with sodium carbonate. nanocomposites. PEEK is available in unfilled, 30% glass filled, 30% carbon filled, and bearing grade (Ketron HPV). Polyetheretherketone (PEEK) is a semi-crystalline, high-performance engineering thermoplastic. 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. PEEK is considered a high-performance polymer, that is to say, its high price restricts its use to the most demanding applications only. Length, width, thickness, and diameter tolerances vary by size, by manufacturer, brand, and grade. hen exposed to flamew Common brands: TECAPEEK ® SustaPEEK Ketron ® Available in: UNITS. ood mechanical properties at G levated temperaturese L 94 V-0 flammability rating (0.059" thickness)U ery low smoke and toxic gas emissions V .
