PEEK Capillaries
PEEK Capillaries - Hard Rigid Resistant High Pressure
Enormous Material Hardness – Highest Pressures
Highest Rigidity with excellent lubricity and boasts a continuous working temperature. Highest tensile and flexural strenght, extreme impact resistance, high dynamic resilience, stress crack resistance, highest thermooxidative stability, rigid and resistant to abrasion ...PEEK is the hardest of all Plastics and reaches mechanical strenght properties of metal.
Optiflon PEEK-Capillary is not swellable and aging resistant. Aside of its mechanical strenght properties it also provides an excellent chemcial resistance.
Applications
Due to its high pressure resistance (up to 600 bar / 8700 psi) Optiflon PEEK is used as alternative to metal in chromatography (HPLC).
