The difference of "Peek" or "Teflon"

PEEK tubing 

Peek tubing refers to tubes made from a high-performance polymer called Polyetheretherketone (PEEK). Here's a breakdown of its properties and uses:

Properties of PEEK Tubing:

  • High Strength and Temperature Resistance: PEEK can withstand high temperatures and pressures, making it suitable for demanding applications.
  • Chemical Resistance: PEEK is resistant to a wide range of chemicals, including harsh solvents and acids.
  • Good Wear Resistance: It has good wear properties, making it suitable for applications where the tubing will experience friction or abrasion.
  • Biocompatible: Certain grades of PEEK are biocompatible, meaning they can be used in medical applications without causing harm to the body.
  • Flame Retardant: Some grades of PEEK are flame retardant, making them suitable for use in safety-critical applications.

Teflon Tubing 

Teflon tubing, also known as PTFE tubing (Polytetrafluoroethylene tubing), is a type of flexible plastic tubing made from the synthetic fluoropolymer PTFE. It's known for its unique properties that make it valuable in a wide range of applications. Here's a breakdown of its key characteristics:


  • Non-stick: One of its most famous properties is its non-stick surface. This makes it ideal for applications where substances need to flow freely without accumulating on the tubing walls.
  • Chemical resistance: PTFE is highly resistant to a wide range of chemicals, including acids, bases, and solvents. This allows it to be used safely with various fluids without the risk of degradation.
  • Temperature resistance: Teflon tubing can withstand a wide range of temperatures, from very low (-450°F) to extremely high (500°F). This makes it suitable for use in harsh environments where other materials might melt or become brittle.
  • Low friction: The smooth surface of the tubing minimizes friction, allowing for efficient flow of liquids and gases through it.
  • Electrical insulation: Teflon is a good electrical insulator, making it useful in applications involving electrical components.
