It helps architects push the boundaries of form and function. It helps keep vehicles on the road longer. And it helps protect equipment in extremely demanding operating conditions. PTFE can even be used as an additive to improve slip or wear characteristics in ink, plastics and lubricants. Its key features include:

  • Exceptional chemical resistance
  • Wide service temperature range
  • Low coefficient of friction
  • Low permeability
  • Long service life
  • Outstanding weather resistance
  • This material data has been provided by M-Base.
