3mm~330mm Virgin PTFE rod

 Virgin PTFE Rod Data Sheet & Specification 

Virgin PTFE rod is produced by extruding high-purity PTFE resin into a dense, consistent cylinder designed for machining applications that require exceptional chemical inertness and thermal stability. Unlike filled PTFE grades, the virgin material retains maximum non-stick behavior, high dielectric strength, and resistance to nearly all corrosive media, making it suitable for precision components used in chemical equipment, fluid handling systems, and electronic assemblies. Small-diameter formats, including the 3mm PTFE rod, maintain tight dimensional control during extrusion, enabling reliable use in miniature seals, analytical instrument parts, valve components, and low-friction sliding elements. Across the full diameter range, the rod exhibits stable mechanical behavior from cryogenic temperatures up to approximately 260°C, with minimal moisture absorption and predictable deformation under compressive loading.

The extrusion process yields a smooth, homogeneous surface ideal for CNC turning, milling, or drilling without fiber separation or particle shedding. The material’s consistent density allows it to be shaped into seats, spacers, insulators, wear pads, and precision rings without compromising chemical compatibility or long-term sealing characteristics. Its inert polymer structure prevents contamination, making the rod suitable for food-grade, pharmaceutical, and ultra-pure applications where material integrity is critical.
