RS PRO Polyetheretherketone Plastic Sheet, Beige, 500mm x 50mm x 5mm, Epoxy Resin, Fine Weave Cotton, Acrylic, 514-679

RS PRO Polyetheretherketone (PEEK) Plastic Sheet, model 514-679, is a premium beige engineering plastic sheet measuring 500mm in length, 50mm in width, and 5mm in thickness. This sheet is composed of high-performance polyetheretherketone reinforced with epoxy resin, fine weave cotton, acrylic, and fibreglass, offering a unique blend of durability, versatility, and advanced mechanical properties.

The PEEK sheet exhibits outstanding strength, rigidity, and toughness, making it an ideal choice for demanding manufacturing environments. Its semi-crystalline structure ensures stable performance under mechanical stress, maintaining high tensile strength of 95MPa and Rockwell hardness (M 99) even in severe conditions. With a flammability rating of UL 94 V-0, this sheet provides enhanced resistance to fire and contributes to safer industrial operations.

Its robust chemical resistance covers a wide spectrum of acids, bases, hydrocarbons, and organic solvents, making the sheet suitable for use in oil and gas, chemical processing, nuclear, electrical, and food-grade applications. The sheet's low water absorption (0.5%) and hydrolysis resistance enable reliable functioning in humid, steam, marine, and aquatic settings. It also demonstrates excellent wear and abrasion resistance, which is critical for frequently used or high-wear parts.

The adhesive backing feature offers flexible and secure installation, allowing easy integration into existing systems and simplifying machining into custom components. With thermal conductivity at 0.27W/mK and a maximum operating temperature of 260°C, the sheet can withstand and insulate in high-temperature scenarios. Its electrical insulation properties and low emissions in vacuum conditions further extend its utility to electronic, medical, and aerospace sectors.

Industrial use cases include oil and gas production, power generating equipment, automotive engineering, packaging and paper processing machinery, electronic and electrical engineering, food processing, medical devices, chemical industries, and aircraft/aerospace manufacturing. Engineers rely on PEEK Plastic Sheets for components subject to repeated wear, aggressive chemicals, and elevated temperatures, replacing glass, stainless steel, and titanium where required for improved performance and longevity.
