![]() It is also highly dimensionally stable when exposed to extreme temperature variations, with its low coefficient of linear thermal expansion.ĭrake Plastics extrudes and injection molds several of the high strength glass and carbon fiber-reinforced PEEK formulations. PEEK also exhibits exceptional resistance to creep or cold flow under load at high temperatures. Actual injection molded parts or parts machined from stock shapes will not likely achieve this best possible result. It is important to note that this value is derived from samples molded with the fibers orientated optimally for testing. Victrex’ properties data lists the heat deflection temperature of its 30% carbon-fiber reinforced Victrex 450 CA30 PEEK, for example, at 520☏ (271☌), a significant step up in performance over unreinforced formulations. In unreinforced grades its heat deflection temperature measures 315☏ (157☌), and fiber-reinforced grades maintain high strength at even higher temperatures. Its properties include a Tg (glass transition temperature) of 302☏ (150☌). PEEK ranks high on flexural and tensile strength at elevated temperatures. Strength retention and dimensional stability at elevated temperatures They are extruded in high volumes under conditions that afford the economics required for certain applications. As is the case with competitive PEEK rod and plate, the products we designate as Drake Industrial Grade PEEK are supplied without resin certifications confirming Mil-P46183 compliance. These premium shapes include those unique to Drake, such as 10-inch/ 255mm diameter rod and plate in 4.0-inch/ 200mm thickness, representing the largest extruded shape sizes available worldwide.ĭrake also offers shapes branded as Drake Industrial Grade PEEK that are equivalent or somewhat higher in quality compared to other commercially available PEEK stock shapes. ![]() Invibio Biomaterial Solutions, a Victrex company, designates their implant grade as PEEK-Optima™, and Solvay brands their implantable product Zeniva® PEEK.ĭrake offers a complete family of PEEK stock shapes, from unreinforced and enhanced bearing and wear grades to glass and fiber-reinforced formulations in the industry’s widest range of sizes.ĭepending on the specific grade of resin used, Drake Plastics applies the Victrex® PEEK or the Solvay KetaSpire® PEEK brands to its optimum quality extruded shapes. More recent developments in PEEK polymers by Victrex PLC and Solvay include biocompatible grades for human implantable and non-implantable life-sciences applications, as well as grades with higher temperature capabilities. The KetaSpire® PEEK product family is also typically melt-processed by extrusion and injection molding and serves numerous industries and applications in the form of molded parts, and extruded stock shapes that are machined into precision components, and extruded film and tube. Commercialized under the designation KetaSpire® PEEK, Solvay’s family of grades includes formulations with performance enhancements for greater wear resistance and structural strength. in the early 2000s and also actively developed products for severe service applications in a range of industries. Solvay began production of PEEK resin in the U.S. Opening these processing alternatives further expanded PEEK’s range of applications and the industries in which the material is specified. Its relatively easy melt-processability also led to adaptations of PEEK resin for diverse processing methods including injection molding, compression molding, and extrusion of fibers, pipe, tubing, film and machinable stock shapes. ![]() Enhanced performance grades include formulations with improved bearing and wear properties and with glass and carbon fiber reinforcement that significantly increases PEEK’s structural strength. These opportunities led to development of PEEK materials that serve a broader range of applications. With the proliferation of parts specified in Victrex® PEEK and engineers’ growing awareness of the material’s capabilities, new application possibilities emerged that were beyond the performance limits of the initial grades. ![]() The company’s application development efforts span more than 40 years and have led to the widespread use of PEEK for components in aerospace, oil and gas exploration and production, semiconductor manufacturing, medical and military and defense equipment. Since the commercial introduction of PEEK in 1980, Victrex PLC has become its leading producer and supplies the ultra high-performance thermoplastic worldwide from its operations in the UK. ![]()
