Our latest grade, PEEK LSG (Medical Grade), & PEEK HPV, offers outstanding properties that can be viewed below. Very high cost per pound - Excellent physical properties above 400o F. First, the PEEK polymerization process must be performed in an oxygen-free state, and. PEEK also has distinctive properties that makes PEEK ideal in biocompatibility, UV resistance, pure radiolucency, gamma-ray resistance, and low/no toxicity in all forms. The most well known and important member of the polyaryletherketone group combines excellent wear, and very good mechanical properties, even under thermal load. To obtain high quality of material, harsh reaction conditions and high technical requirements are required. Its density and tensile strength are high enough to rival metals like aluminum, and it will not degrade in chemically or physically harsh environments as metals do. For more than 35 years, PIE has been an invaluable source of information for European. PEEK maintains its strength and durability against chemicals, fatigue, and creep. The following information is provided by Plastics Information Europe. For hostile environments, PEEK is an alternative to fluoropolymers. Therefore, it is reserved for high value added industrial applications rather than beginner 3D printing. With a low coefficient of friction, these pellets wont wear away from abrasion that’s often caused by contact with moving parts. Commonly a kilo of PEEK filament will cost upwards of 500. As a semicrystalline engineering thermoplastic of the polyaryletherketone (PAEK) family, it maintains high-temperature tolerances, strength, and stability across harsh environments operating continuously at temperatures of 480☏ (250☌) without permanent loss in physical properties. PEEK filament is expensive and can cost 300-500+ per kilo but the benefits are clear: extremely high quality parts can be produced. For AM, PEI is available in two versions, ULTEM 1010 and ULTEM 9085. However, PEI has an extremely high Tg, so it’s not as easy to print as other materials such as PEKK. PEEK or polyetheretherketone offers engineers a high-performance, extremely durable thermoplastic that suits challenging applications in multiple industries. PEI, available for a third of PEEK’s price, also offers excellent layer adhesion and is much easier to print (with the right equipment).
