PI (polyimide) is one of the highest performance polymer available to the market. Due to its extraordinary thermal, mechanical, and chemical properties, the application of PI can be found over a wide breath of industries ranging from aerospace engineering to semi-conductor industries. Our PI has the following characteristics

Mechanical properties:

  • Very high tensile strength and tensile modulus
  • High flexural strength
  • High impact strength
  • Extremely low creep
  • Light weight
  • Wear and abrasion resistant
  • Self-lubricating property
  • Low coefficient of friction
  • Can withstand high P(load) Χ V (speed) applications


Thermal properties:

  • Working temperature ranging from cryogenic to 315 °C
  • Withstand temperature up to 482 °C for intermittent use
  • Very low thermal expansion coefficient (less than 0.005% / °C)
  • Excellent dimensional stability



Chemical properties:

  • Resistant to a wide range of organic and non-organic solvents
  • Resistant to most oil and processing chemicals
  • Extremely low outgassing
  • Volume magnetic susceptibility is close to that of water


Electrical properties:

  • Excellent dielectric property
  • Resistant to radiations

What we offer:

We supply the complete range of PI including unfilled grade for the best mechanical properties, graphite filled and/or PTFE filled grade for better wear properties, and molybdenum sulfide filled grade for special environments

All materials can be supplied in the form of commonly used basic shapes (Rod, bar, plaque, sheet, and tube) of various dimensions. If you are interested in this product, please do not hesitate to contact us via e-mail or our enquiry system.
