![]() PEEK plastics typically come in rods, plates, or injection molded blanks of various sizes. 5 PEEK Machining Tips #1 Anneal PEEK Plastics Before Machining This makes them especially useful in custom medical implants, such as articulating joints. However, in addition to all of these properties, medical-grade PEEK plastics are also chemical resistant and biocompatibleㅡwhich means they don’t have harmful effects on the human body. The medical-grade PEEK possesses all of the mechanical properties of industrial-grade PEEK. Some industrial-grade PEEK plastics are reinforced with carbon fiber, which offers higher strength and abrasion resistance than conventional PEEK plastics. Components made from industrial-grade PEEK are used in the aerospace, automotive, chemical, electronics, and energy industries. The industrial-grade PEEK is a strong, abrasion-resistant thermoplastic with a low coefficient of friction and high impact strength. Fabricating PEEK Plastic Parts: Gensun Can Help.#2 Use the Carbide and Polycrystalline Tooling.#1 Anneal PEEK Plastics Before Machining.Some of the properties of 450G and 150G are compared in the table below to illustrate these differences. This is a consequence of the shorter polymer chains, which are less entangled, crystallise more readily and to a greater overall extent. However, the lower molecular weight also changes the bulk properties of the polymer: lower molecular weight PAEKs have higher stiffness and strength combined with reduced toughness, ductility and impact resistance. As a result, 150G may be more suitable for applications where lower viscosity in the melt during processing is desirable, for example, when injection moulding thin-walled parts or long, thin sections with intricate geometries impregnating carbon or glass fibres for composite prepregs or adding high levels of solid fibrous or particulate fillers and reinforcements to make compounds. VICTREX PEEK 150G is a higher flow, lower molecular weight, lower MV grade of PEEK compared to 450G. Other VICTREX PEEK grades are available with higher and lower melt viscosities and higher or lower molecular weights respectively. VICTREX PEEK 450G is defined as a standard melt viscosity (MV) PEEK grade, with a medium molecular weight. Properties may also differ for along flow and Property values are highly dependent on part geometry, mould configuration and processing conditions. Data are generated in accordance with prevailing national, international and internal standards, and should be used for material comparison.Mould shrinkage is expressed as a percent change in dimension of a specimen in relation to mould dimensions.When it exits the gate and enters the mould. “Along flow” direction is taken as the direction the molten material is travelling Mould shrinkage differs for along flow and across flow directions.Actual mould shrinkage values are highly dependent on part geometry, mouldĬonfiguration, and processing conditions. Data for mould shrinkage should be used for material comparison.Processing conditions quoted in our datasheets are typical of those used in our processing laboratories. ![]() ![]() Specifications for PEEK MATERIAL PROPERTIESġ50☌ / 3h or 120☌ / 5h (residual moisture 3mm, manifold >3.5mm Its unique properties make it an exciting material choice for engineers seeking to create prototypes or production parts with exceptional performance characteristics. In summary, PEEK is a versatile material that offers high performance and has broad applications across different industries. PEEK is known for its excellent thermal and mechanical properties, high strength-to-weight ratio, and resistance to wear, chemicals, and temperature. PEEK filament has a unique set of qualities that make it a preferred choice for various industries such as medical, oil and gas, aerospace, and automotive.įor instance, PEEK is the ideal material for low-volume production and specialist designs that would be challenging to create using traditional techniques or metal. What sets PEEK apart is its exceptional properties, making it one of the top-notch materials in the 3D industry. PEEK, short for polyether ether ketone, is a colorless, organic thermoplastic polymer that belongs to the polyaryletherketone (PAEK) family. As an engineer, you may be interested in learning about the growing popularity of PEEK material for 3D printing.
