Is PEEK a plastic?
PEEK (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water.
When was PEEK created?
November 1978
November 1978 marked the invention of PEEK (polyetheretherketone), a new high-performance polymer (HPP).
Is PEEK plastic food grade?
PolyEtherEtherKetone (PEEK) is a high-performance engineering thermoplastic that offers chemical and water resistance while operate at higher temperatures. All unfilled PEEK grades comply with FDA regulation 21 CFR 177.2415 for repeated food contact.
Why is PEEK so expensive?
Why is PEEK So Expensive? While PEEK’s high temperature resistance can make it difficult to process, in its solid state PEEK is readily machinable by CNC milling machines. Filled grades of PEEK can also be CNC machined, but care must be taken to correctly manage stresses in the material.
Why is PEEK so strong?
Chemical resistance: PEEK displays high resistance amidst a wide range of chemical environments even in high temperature enviroments. It can only be dissolved in concentrated nitric acid or sulphuric acid. Long life: It is a hard, stiff and strong polymer. It displays good friction as well as wear properties.
Does PEEK contain fluorine?
PEEK contains no fluorine, despite being frequently grouped with fluoropolymers like PFA or PTFE. Figure 1. PEEK synthesis and immediate precursors. PEEK is synthesized most immediately from difluorobenzophenone and disodium hydroquinone.
What is PEEK made of?
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 toxic?
At the same time, PEEK emits little smoke or toxic gas when exposed to flame. This material is tough, strong, and rigid and has superior creep resistance. It also resists radiation and a wide range of solvents.
What does PEEK stand for?
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.
Is PEEK stronger than aluminum?
The inherent low specific gravity of VICTREX PEEK (1.3 g/cm3) is less than half that of aluminium and one sixth that of steel. This results in a superior strength-to-weight ratio so VICTREX PEEK-based compounds can offer equivalent strength and stiffness with up to 70% weight reduction.
How is PEEK produced?
Manufacturing Process of PEEK PEEK can been synthesized by using nucleophilic substitution of 4,4′ – difluorobenzophenone with hydroquinone in the presence of anhydrous potassium carbonate under microwave irradiation to produce a good yield.
When was the first PEEK polyetheretherketone made?
PEEK materials were initially made in 1977 by imperial Chemical Industries (ICI) As shown in the table below, there are several polymers in the family of Polyaryletherketones (PAEK) and amongst them, polyetheretherketone (PEEK) is both most widely used and also manufactured in large scale.
What kind of material is a polyetheretherketone?
Polyetheretherketone Polyetheretherketone (PEEK) is a thermoplastic polymer that was commercialized in the early 1980s and later proposed as a material to be used for medical applications (Panayotov et al., 2016).
How is Peek a semicrystalline polyetheretherketone prepared?
Polyetheretherketone (PEEK) is a semicrystalline polyether prepared under milder conditions via aromatic nucleophilic substitution reaction of the potassium salt of hydroquinone and 4,4′-difluorobenzophenone as shown in Figure 2.27.
What are the properties of polyether ether ketone?
Polyetheretherketone (PEEK) is a high-performance, engineering thermoplastic characterized by an unusual combination of properties. These properties range from high temperature performance to mechanical strength and excellent chemical resistance.
