PEEK-rubber composite seals

    Oct. 27, 2011
    The composite resists chemicals, high temperatures, and creep and was designed for industrial seals.

    A composite of polyetheretherketone (PEEK) film, acrylonitrile butadiene rubber (NBR), and fluoroelastomer (FPM) is for low-permeability seals. PEEK provides strength and rigidity with minimal creep while the rubbers resist heat and chemical corrosion. The resulting composite has  low creep under high mechanical loads, little expansion in the presence of fluids and steam, high chemical resistance, and very low permeation.
