Fire Retardant Film for Engine Cowling Purge: Ensuring Aircraft Safety During Maintenance

Aerospace Cowling Purges

Engine cowling purges are crucial for maintaining proper engine operation in aircraft, but they pose fire risks. Learn how fire-retardant films mitigate these risks.

Material Considerations:

  • Fire Retardancy: Look for films meeting industry standards like FAR 25.853 (a) and certifications like ASTM E-84 Class A or NFPA 701.
  • Temperature Resistance: Ensure the film withstands high engine temperatures without degrading.
  • Durability: Choose films resistant to tears, punctures, and abrasions during handling.
  • Weight: Consider the film's weight to avoid impacting aircraft performance.
  • Transparency: Opt for clear films for visibility during the purge process.

Product Examples:

  • Polyimide Films: Offer excellent fire resistance and mechanical properties but may be costly. (Ask us)
  • Flame-Retardant Polyethylene (PE) Films: Provide cost-effective solutions with good fire retardancy and durability.

Additional Considerations:

  • Attachment Method: Ensure secure attachment without damaging the aircraft.
  • Ease of Use: Consider installation, removal, and disposal ease.
  • Environmental Regulations: Ensure compliance with disposal methods and environmental regulations.


  • Consult aircraft maintenance manuals and regulatory guidelines.
  • Contact material suppliers for detailed specifications and fire certifications. Email
  • Test different film options to find the best fit for your application.

Note: This overview serves as a guide. Always consult with qualified professionals and adhere to regulatory requirements for specific applications.
