PCTFE Rods

PCTFE Rod Low-Permeability Chemical-Resistant Fluoropolymer Round Bar Diameter 4–50 mm for Cryogenic Seals, Valves, Aerospace and Precision Machined Components

PCTFE Rod PCTFE rod is a high-performance fluoropolymer round bar designed for precision-machined components requiring low gas permeability, dimensional stability, chemical resistance and reliable performance at low temperatures. PCTFE, or polychlorotrifluoroethylene, has a dense molecular structure that provides lower moisture absorption and lower gas transmission than many conventional fluoropolymer materials. It is often selected for valve seats, sealing components,
