Durable White Hard Plastic Rod Wear-Resistant Molded PTFE Rod for Versatile Use

Extrusion molding is suitable for producing continuous PTFE rods with relatively small diameters and longer lengths, offering a smooth surface and good dimensional stability. Compression molding is ideal for large-diameter, short-length rods or those requiring special filler reinforcement, allowing flexible formulation and density control. If you need rods with a diameter of 5-100 mm, long lengths, and high batch-to-batch consistency, extrusion is recommended. For diameters exceeding 100 mm or a

Our standard diameter range is 5-350 mm, but we also support ultra-fine rods below 5 mm (ideal for precision instruments) and oversized rods above 350 mm (for structural components, seal seats, etc.). Such non-standard specifications require evaluation of mold and forming methods based on the actual dimensions. We recommend providing drawings or technical requirements in advance for custom confirmation.

Common fillers include glass fiber (improves wear resistance and rigidity), carbon fiber (enhances thermal conductivity and creep resistance), copper powder (improves thermal conductivity and compressive strength), and molybdenum disulfide (reduces the friction coefficient). Filler reinforcement compensates for the limitations of virgin PTFE in load capacity, thermal conductivity, or dimensional stability, making the material suitable for higher load or special operating conditions.

We use 100% virgin PTFE resin with no regrind or recycled content. All raw materials are sourced from leading fluoropolymer suppliers, and we provide batch-specific material certifications and physical property test reports to ensure the product meets high standards for purity, mechanical strength, electrical insulation, and more.

Virgin PTFE offers excellent chemical inertness, non-toxicity, and low extractables, meeting the stringent requirements of food contact, medical devices, and high-purity semiconductor processes. If intended for these industries, please specify the relevant standards (e.g., FDA, RoHS, MSDS), and we can provide compliance support and corresponding test reports.
