Its exceptional wear-resistance makes PEEK highly valuable in the production of medical implants as well. It is also lighter than comparable metals, making it popular in the automotive and aerospace industries as it improves a vehicle’s energy efficiency. Another measure of wear is fatigue resulting from repeated pressure and stress, and PEEK performs exceptionally well here too.
This makes it a great material for use in car parts. It also has a low friction coefficient, which means less wear, noise, vibration, and emissions. PEEK can withstand high loading at elevated temperatures without permanent deformation, also known as creep. Tests show PEEK is more durable than many other polymers and even some metals. It can also stand up against jet fuel, hydraulic fluids, and de-icers in the aerospace industry. Therefore, it can withstand chemically aggressive conditions in the oil and gas industry-in sub-sea pipes, gears, and machinery. PEEK is highly resistant to water and many solvents (even when subjected to them in high-temperature and high-pressure steam conditions).
This has led to its wide use in thermally aggressive environments such as oil and gas, and automotive industries. Tests show that PEEK has a high melting point of 341☌, high glass transition temperature of 143☌, and a continuous use temperature of up to 260☌. Let us take a closer look at its properties and how it behaves and influences material selection in various industries: The ether group in PEEK lends flexibility (making it tough) and renders it unreactive (providing resistance to chemical exposure). The aryl and ketone portions of its build-up give PEEK rigidity and stiffness, which means good mechanical performance and a high melting point. PEEK is a semi-crystalline, opaque material belonging to the PolyKetone family of polymers called PAEK, which comprises aryl, ether, and ketone molecule groups. This is what our experts at Xcentric think you should know about PEEK to help you decide whether it is the right material for your needs. Aerospace: Electrical insulators and isolators, battery connectors, external light housings, gaskets, seals, fittings, brackets, clamps, and thermal acoustic insulation.Medical device: Endoscope parts and dental cleaners, implants, surgical devices, joint replacement.Office machinery: Copier claws, special heat-resistant bearings, chains, gears.Automotive: Engine parts, variable speed transmission parts, steering parts, brake components.This makes it a popular choice when manufacturing aerospace and automotive components, medical devices, machinery parts, semiconductors, and electrical and electronic machinery. PEEK often outperforms metal when used in harsh environments. This results in time and cost advantages. Its other properties include electrical insulation, corrosion resistance, and high purity.Īnd because PEEK can be mass-produced by injection molding without involving the machining of metals and the curing of thermosets, there are fewer processing steps. PEEK, however, possesses several of these properties: including mechanical strength, wear-resistance, heat resistance, and chemical resistance. However, most of these fall below expectations when it comes to other demands, such as wear-resistance or mechanical strength. Here is why: Many high-performance polymers can stand up to one or two requirements, either the ability to withstand extreme temperature or chemical exposure. At Xcentric, we have more than 40 resins in stock to choose from and take particular care in advising our clients on material selection.Īmong the small number of high-performance polymers, the PAEK (PolyArylEtherKetone) family leads the way, and, among these, PEEK (PolyEtherEtherKetone) is the most popular. There are thousands of plastic variations available, from everyday commodity plastics to high-performance polymers used in very demanding operating environments. Product developers and engineers are often overwhelmed by the number of injection molding plastics they must choose from to find just the right material to manufacture with.
