What is PEEK 450G?
VICTREX PEEK 450G is a specific grade of PEEK polymer, a unique grade which is only made by Victrex and which has a specific range of molecular weight. The molecular weight defines the bulk properties of the PEEK 450G polymer, including its stiffness, strength, toughness, crystallinity and melt processing behaviour.
What is PEEK material?
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.
Who makes PEEK material?
Ensinger
PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. It is extruded in sheet, rod and tube that may use Victrex® PEEK 450G or Solvay Ketaspire® KT-820 polymer.
How is PEEK manufactured?
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.
Are there different grades of PEEK?
The four top grades of PEEK are: unfilled, 30% glass-filled, 30% carbon-filled, and 20% PTFE and graphite filled. These materials are manufactered into fasteners and components such as bearings, screws, flat washers, hex nuts, gears, and medical components in addition to many custom shapes.
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.
Does PEEK absorb water?
Plastics with very low water absorption are polymers such as PEEK,PPS, PSU, PPSU, PEI, PVDF, PET, PPE, PP and PE. Furthermore, low water absorption is exhibited by POM, PA12, PC and ABS.
Is PEEK waterproof?
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.
Does PEEK degrade over time?
It has been found that accelerated degradation on the mechanical properties and wear resistances of PEEK and its composites are induced by increased hydrostatic pressure in the deep sea, indicating possible microstructure transformation induced by increased hydrostatic pressure.
Why is PEEK so strong?
But what makes PEEK such a dynamic material? Polyetheretherketone refers to a semi-crystalline organic polymer thermoplastic exhibiting a highly stable chemical structure. Consequently that gives it an edge over other materials. It is a member of the Polyaryletherketone or PAEK polymer group.
Is PEEK plastic toxic?
As a plastic, PEEK is not considered toxic, even when exposed to fire, and is easy to recycle.
Is PEEK food Safe?
Polyetheretherketone (PEEK)
PEEK is safe for direct contact with delicate foods like raw lettuce or fresh dairy products even during the production process. For this reason, PEEK food handling components are used in both food packaging and food production processes.
What is medical grade PEEK?
TECAPEEK MT medical grades (PEEK) are high performance materials with an exceptional mechanical property profile, largely maintained at high temperatures above 212°F. PEEK medical grades (Ensinger TECAPEEK MT) exhibit excellent resistance to customary methods of sterilization.
What is Virgin PEEK?
Virgin VICTREX PEEK (unfilled) is a semi-crystalline thermoplastic typically used as a replacement for machined metals in a wide variety of high-performance end-use applications.
Can PEEK be glued?
The high-performance plastic PEEK is considered difficult to bond. This has been proven wrong through recent testing performed jointly by Evonik and DELO. Thanks to special epoxy resins, the bonded connections exhibit excellent strength even under demanding environmental conditions.
What temperature can PEEK withstand?
PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170oC). This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, food and beverage processing, and semiconductor.
What is the use of PEEK?
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.
Is PEEK eco friendly?
In short, PEEK itself does not have a significantly negative impact on the environment during its creation, service-life, or end-of-life disposal.
Can you sterilize PEEK?
With its resistance to hydrolysis, PEEK can withstand boiling water and superheated steam used with autoclave and sterilization equipment at temperatures higher than 482° F.
Is PEEK material FDA approved?
FDA Compliant PEEK– grades available that meet FDA requirements. Optical, Metal and X-ray Detectable PEEK– TECAPEEK® UD is a dark blue FDA compliant detectable PEEK designed for the food and beverage processing and pharmaceutical industries.
Are PEEK implants safe?
The choice of polyetheretherketone (PEEK) as a reconstructive material in craniofacial defects has proven to be a safe method, with good clinical results when compared to other reconstruction materials.
Is PEEK biodegradable?
The PEEK waste is not biodegradable. Toxicity of PEEK is expected to be low based on insolubility of polymer in water.
Does epoxy bond to PEEK?
However, recent test results demonstrated that VESTAKEEP® PEEK L4000G can be bonded to other materials using an adhesive based on a heat-curing epoxy developed by DELO. VESTAKEEP® PEEK L400G offers the strongest bonding strength with or without pre-plasma treatment.
Does epoxy stick to PEEK?
Higher temperature resistant plastics such as PEEK and PBT can be bonded with special heat cure epoxy.
What is a PEEK implant made of?
Abstract. Background: Polyetheretherketone (PEEK) is a synthetic material that was used initially in spine and hip surgery. It has the properties of being biocompatible, resistant to thermal and ionizing radiation, and resembles cortical bone biomechanically.
