Novenco PTFE Rods
NOVENCO produces PTFE Rods and Tubes in a wide range of sizes, colors, and PTFE materials.
PTFE RODS & TUBES
NOVENCO produces PTFE Rods and Tubes in a wide range of sizes, colors, and PTFE materials (Poly tetra fluoro ethylene), including our NEC 12 Rod or Tube is a low friction product that is inert to most liquids and corrosives, and is also noncontaminating, making it the perfect material for use in applications where metals and alloys would corrode quickly. Capable of withstanding temperatures from 328°F up to +500°F. NEC 12 can handle a vast range of environments and is thus, used regularly in high temperature applications.
While NEC 12 Rods and Tubes are mostly white in color, they can also be made from blended materials to meet customer application requirements. Adding a filler will generally color the Rod or Tube to match the filler, but other custom colors can also be obtained. However, custom colors must be requested prior to fabrication. Certain fillers or colors may affect the physical properties of the material. Please inform us if testing of a certain blend is required.
NOVENCO stocks a wide range of molded and extruded tubes and rods, in virgin PTFE + Recycled PTFE as well as blended compounds which help us to ensure fast and efficient service. We usually stock rod made of a combination of virgin PTFE + Recycled PTFE.
