Polyether ether ketone, or PEEK, is a high-performance engineered polymer with excellent heat tolerance and one of the highest strength-to-weight ratios of any thermoplastic. This material can be used as an alternative to other materials such as aluminum, steel, glass, and other polymers. PEEK’s strength is complemented by its lubricity and high purity for demanding applications.
Our research, engineering, and production teams have developed a diverse collection of PEEK products to fuel innovation for applications in medical, oil and gas, aerospace, automotive, and high-performance liquid chromatography (HPLC). We also have developed our Thermally Stable PEEK coating for fiber optics with extremely low attenuation throughout a range of 250 Celsius degrees. This rigid plastic is considered one of the highest performing materials of its kind. PEEK’s considerable advantages as a material science solution are generating breakthroughs in many markets.
PEEK is replacing many metal parts allowing innovative applications with flexibility while reducing costs and weight for systems. In analytical applications, PEEK’s high burst pressure, purity, and chemical resistance assure that PEEK tubing will stand up to the pressures needed for critical laboratory work and not contaminate the results. In a biomedical setting, PEEK can be subjected to sterilization procedures such as autoclaving and gamma irradiation.
