Polyetheretherketon, formally known as polyether ether ketone, is a high-performance engineering thermoplastic with unique characteristics. This rigid material belongs to the polyketone polymer family and is the most widely used type of this family, usually produced in large quantities. Polyetheretherketon is a highly processable semi-crystalline thermoplastic material with excellent heat resistance, mechanical strength and chemical resistance. Additionally, its polymer structure has excellent environmental resistance, dimensional stability, and mechanical strength.
Some of the main advantages of polyetheretherketon include: strong and hard with high fracture resistance; can be easily machined with diamond film, polycrystalline diamond (PCD), or polished hard alloy tools; excellent resistance to seawater, solvents, chemicals, hydrolysis, and many other submerged environments; can withstand long-term exposure to temperatures around 480°F (250℃); exposure to higher temperatures in steam or high-pressure environments does not have a negative impact on its rigidity; melting point is about 650°F (343℃); low toxicity and gas emissions when exposed to flames. Safe for use in many high-temperature environments; creep resistant, even suitable for ultra-high vacuum pumps at high temperatures; polyetheretherketon is suitable for extremely harsh environments, making it an outstanding high-strength substitute for fluoropolymers; polyetheretherketon can be high-pressure sterilized to increase hygiene and medical applications.
Polyetheretherketon dissolves very slowly in concentrated acid solutions such as high molar concentration nitric acid and sulfuric acid. The addition of glass or carbon fiber fillers enhances its physical properties, such as higher thermal stability and mechanical strength. Polyetheretherketon is both durable and wear-resistant. Even in harsh environments and long-term wear applications, it has an impressive service life. Finally, polyetheretherketon is highly biodegradable resistant. Many of the functionalities listed above contribute to this. Unless actively recycled or processed, parts, products, and implants made of polyetheretherketon can be used for a long time.
Polyetheretherketon has various types and grades, some of which are more suitable for specific purposes than others. Due to the physical properties of polyetheretherketon, parts made from polyetheretherketon include bearings, piston parts, aerospace materials, medical prosthetics, etc., with the total number of applications increasing every year. Due to polyetheretherketon's many advantages, it has become the preferred material for many challenging environments. Industries that use polyetheretherketon include medical, oil and gas, aerospace, food and beverage, etc. Common parts and products made with polyetheretherketon include bearings and bushings, automotive parts, semiconductor machinery, seals, food processing equipment, piston parts, pumps, high-efficiency liquid chromatography columns, compressor plate valves, cable insulation, medical prosthetics and implants.
