Its key features include:

  • Outstanding resistance to sunlight/UV exposure and good resistance to γ radiation (radiation resistance)
  • Tremendous chemical resistance to a wide range of aggressive chemicals
  • Excellent burn characteristics / flame and smoke properties (excellent intrinsic fire resistance)
  • Easy processing on industry-standard equipment and easy post-processing such as welding and fabrication
  • Extremely high purity for the most demanding applications
  • Extremely high electrochemical stability
  • Excellent abrasion resistance
  • High temperature rating: RTI 150º C
  • Chemical inertness to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, alcohols, etc.
  • Low coefficient of friction
  • This material data has been provided by M-Base.

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
