Continuous Long-length PTFE Extruded Rod for Corrosion-resistant Support Members

Extruded rods suit longer continuous lengths at lower cost for standard diameters and general support. Molded rods handle large diameters (up to 350 mm) and thick walls with higher density, better creep resistance, and compressive strength - ideal for heavy-duty or precision-machined supports. Choose based on diameter, length, and load conditions.

Yes, diameters from 5 mm to 350 mm are available. Extrusion excels at small-to-medium diameters in long lengths, while molding covers large diameters. Length is customizable; extruded rods can be produced continuously, molded rods in segments. Maximum length depends on diameter.

Common fillers include glass fiber, carbon fiber, graphite, molybdenum disulfide, and bronze. Glass and carbon fiber improve rigidity and creep resistance; graphite and MoS2 reduce friction; bronze enhances heat dissipation. Selection depends on load, friction, and temperature.

Pure PTFE resists almost all strong acids, bases, and organic solvents. Chemical resistance of filled versions depends on the filler - generally suitable for acids, bases, and solvents, but strong oxidizing acids require caution. Provide your specific media for compatibility confirmation.

Extrusion can produce continuous long rods, typically supplied in coils or straight lengths, reaching several meters or more depending on diameter. Smaller diameters can be longer; larger diameters are limited by production and transport but remain customizable.
