Zeus PEEK Tubing
Categories: Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Unreinforced

Material Notes: PEEK (polyetheretherketone) is a high-performance engineered polymer with excellent endurance to heat 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 is very strong while having excellent lubricity and purity for demanding applications.
