![]() ![]() Many parts made from PEEK are found in environments where temperature or chemical exposure poses a problem. PEEK plastic is available in blocks, rods, sheets, pipes, powders, or pellets. PEEK plastic, also known as polyether ether ketone is a high-performance thermoplastic polymer. In today's advanced world, engineered plastics such as PEEK are sought after to replace metals and increase the performance of certain parts. Plastic has evolved tremendously since its first uses in society, and every day, new uses and modifications are discovered. In addition, high purity grades of PTFE are often used in fluid handling systems in the semiconductor industry.HOW TO PROCESS PEEK MATERIAL | PEEK INJECTION MOLDING VS PEEK MACHINING It is also utilized for electrical insulation, isolation, and low friction bearing components. PTFE is often used in backup rings and specialty seals. PTFE is stable at temperatures up to 500˚F (260˚C) Compared to other polymers, its mechanical properties are lower, but its flexibility at low temperatures is considered a key feature. PTFE (polytetrafluoroethylene) belongs to the fluoropolymer family, and the presence of fluorine allows it to provide high electrical, chemical, and acid resistance. Combined with solid creep and fatigue resistance, these characteristics give it unique features not seen in most other polymers. It maintains nearly consistent mechanical and physical attributes at temperatures up to 30 degrees hotter than standard PEEK. ![]() PEK (polyether ketone) is a ketone-based, semi-crystalline, high-performance thermoplastic with excellent thermal dimensional stability, low flammability, strong chemical resistance, and mechanical qualities over a wide temperature range. We already know that PEEK performs as a robust semi-crystalline thermoplastic with high resistances to many demanding environmental factors. When presented with a need for a material able to withstand harsh, high-temperature environments, the best choices usually come down to PEEK, PEK, and PTFE. The impressive number of applications for PEEK continues to increase. Industries that take advantage of PEEK include medical, oil and gas, aerospace, food and beverage, and more.Ĭommon parts and products PEEK is used for include: Thanks to the many benefits PEEK enjoys, it has become the first choice of material for many challenging environments. Because PEEK’s physical properties allow it to be used in a wide variety of industries, parts made from PEEK include bearings, piston parts, aerospace materials, medical prostheses, and many others, with the total number of applications growing every year. PEEK comes in many types and grades, some of which lend themselves to specific purposes more than others. Unless it’s being actively recycled or disposed of, parts, products, and implants made from PEEK can be relied on to last an extremely long time. Many of the features listed above help explain why. It has an impressively-long lifetime, even in hostile environments and prolonged wear applications.įinally, PEEK is exceptionally resistant to biodegradation. PEEK is both durable and resistant to wear. When glass or carbon-fiber fillers are added, it enjoys enhanced physical properties, such as higher thermal stability and greater mechanical strength. It can be autoclaved for increased sanitation and medical applications.ĭissolves very slowly when exposed to concentrated acid solutions, such as high molarity nitric and sulfuric acids Suitable for extremely harsh environments, making it an excellent high-strength alternative to fluoropolymers Suitable for use in ultra-high vacuum pumps Safe for many high-temperature environmentsĬreep-resistant, even at high temperatures Has a melting point of about 650☏ (343☌)Įxtremely low toxicity and gas emission when exposed to open flames. Exposure to even higher temperatures in steam or high-pressure environments will not negatively affect its rigidity.

Some of the main benefits of PEEK include: In addition, its polymer structure allows for exceptional environmental resistance, dimensional stability, and mechanical strength. PEEK is a highly-machinable semi-crystalline thermoplastic that has excellent heat resistance, mechanical strength, and chemical resistance. ![]()
