Unlocking the Versatility of polyether ether ketone (PEEK)
What is PEEK
In the family of polyaryletherketone (PAEK) materials, the colorless organic thermoplastic polymer known as polyether ether ketone (PEEK) is put to use in engineering.
PEEK is a semicrystalline thermoplastic with good thermal stability and strong mechanical and chemical resistance. The crystallinity and, by extension, the mechanical properties of PEEK can be affected by the molding process. Tensile strength is 90 to 100 MPa, while Young’s modulus is 3.6 GPa. PEEK melts at around 343 °C (662 °F) and has a glass transition temperature of about 143 °C (289 °F). The maximum usable temperature for some classes is 250 degrees Celsius (482 degrees Fahrenheit). It can withstand high temperatures without degrading and can also withstand organic and aqueous environments without being damaged. At high temperatures, it is vulnerable to attack by halogens, strong acids, and even certain halogenated chemicals and aliphatic hydrocarbons. At normal temperature, pure sulfuric acid dissolves it completely.
Bearings, piston components, pumps, HPLC columns, compressor plate valves, and cable insulation are just some of the many products that take advantage of PEEK’s durability. It’s a rare type of plastic that can be used in environments with extremely low humidity and high pressure. The chemical processing, automobile manufacturing, and aerospace sectors all rely heavily on it.
At Fluorocarbon, we use compression molding to create rod, tube, and sheet from PEEK. We also manufacture machine-completed components for the aerospace, semiconductor, petrochemical, and oil and gas sectors. Mechanical property testing helps us ensure only the best materials are used. In-house testing of all materials against international standards ensures a constant level of product quality without sacrificing turnaround times.
