PTFE Tubing

PTFE Tubing

 

(PolyTetraFluoroEthylene)

Polyflon offers the highest quality PTFE tubing produced from only premium virgin raw material grades. Close attention is always paid to finished surface smoothness, ID/OD concentricity and circularity.

Key Features of PTFE Tubing:

  • Outstanding low friction/non-stick properties
  • Excellent resistance to almost all solvents, acids & bases
  • Very wide temperature range from -270°C (-454°F) to 260°C (500°F)
  • Virtually unaffected by oxygen, UV light & ozone
  • Most PTFE-tubing grades FDA conforming & USP Class VI compliant

Availability of PTFE Tubing:

  • In coils or on spools
  • Straight pieces with clean, square cuts
  • Can be supplied in heat sealed PE bags to maintain cleanliness
  • Spiral cut for wire/cable management
  • Longitudinally slit for ‘snap on’ sleeving
  • Carbon filled for improved conductivity, ceramic filled for better wear
  • Pigmented (solid/striped) for quick media identification
  • Can be supplied as finished tubing assemblies with connectors etc…
