Polymer Seals

    March 9, 2006
    High-performance polymer seals withstand high-viscosity, abrasive fluids, and high cycling velocities inherent in cold-adhesive dispensing applications.

    The low-cost seals are reportedly field proven over millions of cycles in adhesive-dispensing valves. The seals are made of blended PTFE or other engineered polymers, and use pressure-energized, canted-coil spring technology. This provides near-constant contact force over a wide range of working deflections and allows wide tolerances between mating parts. Coupling PTFE's wear-resistant/lowfriction/chemical compatibility properties with the advantages of canted-coil spring technology lets the products meet demanding requirements. In addition, a metal locking ring pressed into the housing of each seal reduces diametrical shrinkage.
