Polyether ether ketone.
Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.

What does PEEK stand for in medical terms?
polyether ether ketone
PEEK is short for polyether ether ketone, which means it’s a member of the polyaryletherketone, or PAEK, family.
What is PEEK used for?
PEEK is used to fabricate items for demanding applications, including bearings, piston parts, pumps, high-performance liquid chromatography columns, compressor plate valves, and electrical cable insulation.
What kind of material is PEEK?
thermoplastic
WHAT IS PEEK MATERIAL? PEEK material (polyetheretherketone) is a high-performance semi-crystalline engineering thermoplastic with outstanding harsh chemical resistance, very low moisture uptake, good fire performance, excellent mechanical strength across a broad temperature range, and good dimensional stability.
Is PEEK a fluoropolymer?
PEEK is synthesized most immediately from difluorobenzophenone and disodium hydroquinone. Note that PEEK does not contain fluorine and therefore is not a fluoropolymer.
What is a PEEK implant?
Background: Polyetheretherketone (PEEK) is a synthetic material that was used initially in spine and hip surgery.PEEK implants were fashioned from high-resolution CT scans of each patient and sterilized preoperatively before cranioplasty was performed using standard techniques.
What is PEEK in dentistry?
PEEK is used in dentistry as an alternative to metal braces and hooks in removable partial prostheses. In comparison with chrome-cobalt-based partial prostheses, PEEK hooks have been shown to have lower retentive strength (48).
Can PEEK be extruded?
PEEK tubing exhibits high column strength, as well as high tensile strength and high flexural modulus, making it perfect for catheters and other tubing applications requiring good torque response and pushability. Extruded PEEK tubing is used in medical applications where exceptionally high rigidity is needed.
What is PEEK desktop?
Windows Aero Peek (also called Desktop Preview) is a cool new feature in Windows 7 that lets you “sneak” a preview of windows that are on your taskbar so you can more easily sift through the multitude of windows you use daily.The feature will only work if you have more than one window open.
Can you machine PEEK?
PEEK is a machinable thermoplastic, but critical steps must be taken before, during, and after machining to deliver the best end product. Annealing: Annealing is a process performed on PEEK rods to relieve stress and reduce the chances of stresses and surface cracks in the PEEK material during machining.
What color is PEEK?
It can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. Unfilled PEEK has been approved by the FDA for food contact applications since 1998. PEEK is naturally a very light brown or tan color as displayed in our images below, and is also available in black.
Is PEEK waterproof?
It offers hydrolysis resistance to steam, water, and sea water. PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170oC).
Is PEEK expensive?
In a nutshell, PEEK’s ability to stay dimensionally stable under harsh environments makes it a highly sought after polymer. OEMs who use PEEK do so knowing well that for the properties offered, PEEK is unique and therefore expensive.
Why is PEEK so expensive?
Why is PEEK So Expensive? The price point for PEEK (polyetherketone) often comes as a surprise to clients. However, these other polymers can’t compete with the advanced properties of PEEK.PEEK is commonly used to produce high-quality plastic parts that electrically and thermally insulating, as well as thermostable.
Does PEEK contain fluorine?
Note that PEEK does not contain fluorine and therefore is not a fluoropolymer. Conventionally the synthesis of PEEK was difficult as it is not soluble in the majority of common organic solvents. Early attempts produced PEEK of a low chain length that precipitated early and had a fully amorphous structure.
Is PEEK a Teflon?
PTFE is an outstanding electrical insulator over a wide range of temperatures and frequency. PTFE is a thermoplastic.PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.
Why is PEEK good for implants?
PEEK as a flexible biomaterial is still an excellent weight-bearing material suitable for orthopedic and spinal implants. PEEK’s ability to bend resembles the behavior of bone. This feature makes it an excellent replacement for other orthopedic implants, such as titanium which is stiffer than bone.
Why is PEEK used in medical implants?
“Many medical device manufacturers now use implantable PEEK as a way to improve the biocompatibility of load-bearing implants. It makes implants much more bone-friendly and is also much more compatible with diagnostic imaging than metal implants.
What is a titanium Cranioplasty?
Abstract. Objectives: Titanium cranioplasty (TC), the operative repair of a skull defect with an ergonomically manufactured plate to restore cosmesis, cranial function and reduce complications is a common neurosurgical procedure. It is technically simple but has high complication rates.
What is a peek abutment?
Use for fabrication of cement- or screw-retained provisional restorations (up to 30 days). Includes a snap feature that creates a friction fit to retain the abutment during provisionalization.
What is flexible denture?
Flexible dentures are a type of partial denture, which are typically constructed of nylon, or other thin thermoplastics, which differ significantly from the thicker, harder acrylic that is often used in normal dentures.
